In addition to Jeep four-wheel-drive traction and utility, the Grand Cherokee SRT8 takes capability to a new level by giving driving enthusiasts extreme performance for the street and track.<br /><br />“Our new benchmark performance SUV effectively broadens the Grand Cherokee portfolio, and will continue to draw new customers into Jeep showrooms,” Manley added.<br /><br />Designed and built using the proven SRT formula that raises the performance to astonishing levels, the new 2012 Jeep Grand Cherokee SRT8 runs from 0-60 mph in 4.8 seconds, 0-100-0 mph in the mid-16 second range, can cover the quarter mile in the mid-13 second range, has a top speed of 155 mph, and brakes from 60-0 mph in 116 feet.<br /><br />Owners of any Chrysler Group SRT vehicle receive one day of professional driving instruction from the Richard Petty Racing School as part of the SRT Track Experience, designed to maximize their driving knowledge and skills on the street or track. Sessions are held throughout the year at selected tracks.<br /><br />Awe-inspiring powertrain<br />Powering the 2012 Jeep Grand Cherokee SRT8 is Chrysler Group’s all-new 6.4-liter HEMI® V-8 with Fuel Saver Technology that delivers an estimated 465 horsepower and 465 lb.-ft. of torque – an improvement of 45 horsepower and 45 lb.-ft. torque over the 6.1-liter HEMI V-8 it replaces.<br /><br />An active intake manifold and high-lift camshaft with cam phasing delivers maximum low-end torque while optimizing high-end power across a wider and improved rpm band. Specifically,<br />90-percent of peak torque is available between 2,800 and 6,000 rpm, allowing for inspired standing starts and improved straight-line performance.<br /><br />Standard Fuel Saver Technology and a new-for-2012 active valve exhaust system allows four-cylinder operation to engage over a wider rpm range, to deliver both improved fuel efficiency – an estimated 13-percent increase on the highway – and an extended range of approximately 450 miles on one tank of gas.<br /><br />Standard steering wheel mounted paddle shifters join the standard AutoStick on the floor. Both are mated to a proven automatic transmission, allowing a choice of spirited shifting on the road and the race track. Both methods give the driver the ability to shift while the transmission controller calibration prevents situations that might over rev the engine. Fully adaptive electronic control of all shifting makes the powertrain more responsive while minimizing harshness.<br /><br />Outstanding ride, handling and capability<br />For 2011, all Jeep Grand Cherokee models boast an improved and refined on-road ride thanks in part to the vehicle’s body structure. Torsional stiffness was improved 146 percent versus the previous model, for improved ride, durability and reduced noise, vibration and harshness. The improvement is achieved with more than 5,400 welds in the body alone, marking a 53-percent increase in spot welds, a 42-percent increase in arc welds and a 38-percent increase in structural adhesive.<br /><br />With the new 2012 Grand Cherokee SRT8, engineers have improved handling even further.<br /><br />The best handling Jeep vehicle ever – capable of .90 g on the skid pad – features a new SRT-tuned, adaptive damping suspension managed by the new Jeep Selec-Track system that interacts with several different systems (stability control, adaptive damping, transmission shift strategy, transfer case torque proportioning, Electronic Limited Slip Differential performance, throttle control and cylinder de-activation) to automatically tune the dynamics of the vehicle. Drivers can manually choose between five dynamic modes for specific driving conditions:<br /><br />• Auto: provides the most compliant ride and automatically adapts to any road situation using the adaptive suspension tuning<br />• Sport: provides enhanced body control for a sporty, fun-to-drive ride for the street<br />• Tow: provides a safe reduction in pitch and bounce for enhanced towing capability<br />• Track: provides the high-performance, firm, “track-tuned” suspension option to lock down body motion for the ultimate handling experience<br />• Snow: provides the most conservative dynamic mode, so the vehicle will safely stay<br />in-line in inclement winter weather conditions<br /><br />The standard Jeep Quadra-Trac active on-demand four-wheel-drive transfer case uses input from a variety of sensors in order to determine tire slip at the earliest possible moment and take corrective action. The system uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before slippage occurs. When tire slippage is detected, the Jeep 4×4 system can transfer up to 100 percent of available torque to one rear wheel.<br /><br />The transfer case also enhances handling by proportioning torque between the front and rear axles to maintain the driver’s intended path. The new Grand Cherokee SRT8 also features an Electronic Limited Slip Differential that eliminates rear wheel slip and improves handling.<br /><br />The performance-tuned, fully-hydraulic steering system is improved with a new, heavy-duty pump and pump cooler. Revised gearing gives drivers more direct feel and on-center response.<br /><br />New split 5-spoke, 20-inch forged aluminum wheels ride on P295/45ZR20 Pirelli PZero run-flat tires (standard All-season or available Three-season).<br /><br />Rounding out the capability of the 2012 Jeep Grand Cherokee SRT8 is a trailer tow rating of 5,000 lbs.<br /><br />Outstanding braking<br />Chrysler Group’s SRT vehicles are well known for their world-class braking. Stopping power for the 2012 Grand Cherokee SRT8 comes courtesy of new SRT high-performance Brembo brakes with four-wheel anti-lock brake system (ABS).<br /><br />Stopping distance performance of 116 feet from 60-0 mph is made possible by new red-painted, Brembo 6-piston (front) and 4-piston (rear) calipers, and vented rotors at all four corners measuring 15-inches (front) and 13.8-inches (rear).<br /><br />Aggressive and functional exterior<br />The functional performance exterior of the 2012 Grand Cherokee SRT8 features the “planted” look of a high-performance sports car by being lowered 1 inch and adding new, SRT-exclusive, body-color wheel flares and side sill cladding.<br /><br />A one-piece front fascia contains new LED multi-function daytime running lamps that result in an exclusive face for the new Jeep Grand Cherokee SRT8, while a body-colored front grille with a unique black screen background and chrome bezel inserts adds to the aggressive look.<br /><br />The integrated lower front grille is painted in gloss black and a newly designed underbody belly pan features integrated brake ducting to improve cooling and fade performance. Completing the new front end is a newly sculpted hood with functional dual black heat extractors for added engine cooling.<br /><br />At the rear, the SRT performance influence continues with a new liftgate spoiler that reduces drag and improves downforce. A unique one-piece rear fascia includes a separate air diffuser along with an available trailer receiver and access cover. New for the 2012 version of the Grand Cherokee SRT8 is the dual-sport exhaust system featuring 4-inch exhaust tips.<br /><br />Race-inspired and functional interior<br />The 2012 Jeep Grand Cherokee’s refined, luxurious interior takes on a performance feel in SRT8 form with race-inspired technology and SRT-exclusive appointments.<br /><br />An all-new, leather-wrapped, heated steering wheel features a unique rim section with a flattened bottom surface – evoking a race-inspired cockpit – that showcases the SRT logo. Standard paddle-shift controls flank both sides of the new contoured palm rests while all audio and Electronic Vehicle Information Center (EVIC) controls are accessible from the horizontal spokes on the steering wheel. A power tilt and telescoping steering column also is standard.<br /><br />SRT-exclusive Performance Pages are new for 2012 and show instant feedback on steering input measurements, horsepower, torque, 0-60 mph time, 60-0 mph braking distance, g-forces, and one-eighth mile and quarter-mile times, along with expanded engine information.<br /><br />New SRT-styled Nappa leather and suede seats, with sculpted bolsters and adjustable headrests, provide all the comfort for daily drives – and “grip” to keep the driver and passengers in place during spirited driving. The embroidered SRT logos and contrast stitching accent the two front seats. Heated (front and rear) and ventilated (front) seats are standard.<br /><br />Carbon fiber accents are integrated into the instrument panel and door trim panels and new bright, racing style brake and pedal pads add to the high-performance look inside the cabin.<br /><br />An available CommandView® dual-pane sun roof provides twice as much glass surface than a standard sun roof and extends from the windshield to the rear of the vehicle.<br /><br />The available Luxury Group package adds premium leather to the door trim panels, instrument panel and center console along with a power liftgate, adaptive cruise control, Forward Collision Warning and Blind-spot Monitoring.<br /><br />Safety and security<br />Already a recipient of the 2011 Insurance Institute for Highway Safety (IIHS) ‘Top Safety Pick’ for the volume Grand Cherokee models, the 2012 Jeep Grand Cherokee SRT8 offers consumers 45 safety and security features including:<br /><br />• Active head restraints: Deploy in the event of a rear collision. Restraints are designed to reduce injuries by minimizing the gap between the head restraint and the passenger’s head<br />• Active turn signals: Turn signal flashes three times when stalk is depressed for one second to indicate a lane change<br />• Adaptive cruise control (ACC): The system decreases the vehicle’s pre-set cruise-control speed when closing in on another vehicle in the same lane, or when another vehicle pulls into the same lane. The system will accelerate to the pre-set speed when the vehicle in front speeds up or moves into another lane. ACC will maintain a driver adjustable distance between the vehicle and the one in front of it, allowing the use of cruise control in light traffic without having to continuously adjust settings<br />• Advanced multi-stage air bags: Inflates with a force appropriate to the severity of the impact Meets FMVSS 208 advanced air bag requirements for smaller, out-of-position occupants<br />• Anti-lock brake system (ABS): Senses and prevents wheel lockup, offering improved steering control under extreme braking and/or slippery conditions<br />• Anti-lock brake system with rough-road detection: Anti-lock brake system capable of detecting if the vehicle is driving on a rough road by the oscillations in the wheel speed signals. When rough road is detected on off-road surfaces or trails, ABS enters a different pressure control where it will hold the brake pressure for longer pulses<br />• BeltAlert: Activates a chime and/or illuminates an icon in the instrument cluster to remind the driver and front passenger to buckle up if a vehicle is driven without belted front-seat occupants<br />• Blind-spot Monitoring (BSM): Uses dual ultra-wideband radar sensors to aid the driver when changing lanes, or if being passed by or passing unseen vehicles. The system notifies the driver of vehicle(s) in their blind spot via illuminated icons on the sideview mirror and with a driver-selected audible chime<br />• Brake Assist: In an emergency brake situation, the system applies maximum braking power, minimizing the stopping distance<br />• Brake Override: When a disagreement exists between the throttle and the brake, the brake signal causes the engine controller to reduce engine power, allowing the operator to stop the car<br />• Brake-traction control system (BTCS): Helps to keep driving wheels from spinning<br />during acceleration from a stop or during slow speeds by applying individual brakes to the slipping wheel(s)<br />• Child seat anchor system: LATCH (Lower Anchors and Tethers for CHildren) is designed to ease installation of compatible aftermarket child seats<br />• Constant-force Retractors (CFR): Regulates the force exerted on the occupant by the seat belt, and then gradually releases seat-belt webbing in a controlled manner<br />• Electronic roll mitigation (ERM): An extension of electronic stability control (ESC). Uses input from ESC sensors to anticipate if the vehicle is at risk of entering a potential roll situation, then applies the brakes individually and modulates the throttle position as needed<br />• Electronic stability control (ESC): Enhances driver control and helps maintain directional stability under all conditions. Provides the benefit in critical driving situations such as turns, and is valuable when driving on mixed surface conditions including snow, ice or gravel. If there is a discernible difference between driver input through the steering wheel and the vehicle’s path, ESC applies selective braking and throttle input to guide the vehicle back on to the driver’s intended path<br />• Energy-absorbing steering column: The power-adjust steering column employs a calibrated bending element that deforms during column stroke for optimal energy management<br />• Enhanced Accident Response System (EARS): Makes it easier for emergency personnel to see and reach occupants in the event of an accident by turning on the interior lighting and unlocking doors after air bag deployment. Also shuts off flow of fuel to the engine<br />• Express Up/Down Windows: One-touch powered express up/down window button located on the front driver and passenger-side door<br />• Forward Collision Warning (FCW): Using forward-facing radar sensors, this system detects when the vehicle may be approaching another vehicle too rapidly and alerts the driver so the driver can determine what action must be taken in order to prevent the vehicle from a collision<br />• High-intensity discharge (HID) headlamps: Provide approximately three times the light output of conventional reflector lamps for improved nighttime illumination<br />• Hill-start Assist (HSA): Assists drivers when starting a vehicle from a stop on a hill by maintaining the level of brake pressure applied for a short period of time after a driver’s foot is removed from the brake pedal. If throttle is not applied within a short period of time after the driver’s foot is removed from the brake pedal, brake pressure will be released<br />• Keyless Enter-N-Go: When an individual enters the vehicle, electronic sensors detect if the vehicle key fob is present. The vehicle will then allow the individual to push a button to start the vehicle without having to insert the key into the ignition<br />• Knee bolsters: The lower instrument panel and the glove-box door are designed to properly position the occupant during impact, enabling air bags to work effectively<br />• Navigation system: Voice-activated navigation system available with real-time traffic to provide precise guidance to destination through the use of global positioning system (GPS) satellite technology<br />• ParkSense® rear park assist system: Assists at low speeds in reverse to detect stationary objects. Consists of audible warnings for the driver and has a display in the Electronic Vehicle Information Center (EVIC) integrated into the instrument cluster<br />• ParkView® rear back-up camera: Provides a wide-angle view of the area immediately behind the vehicle, giving the driver greater peace of mind before reversing at low speeds. Contains grid line to aid the driver when maneuvering into parking spaces or narrow areas. Also aids in lining up a trailer to the vehicle’s trailer hitch, when so equipped. The image is displayed on the navigation screen when the transmission is shifted into Reverse<br />• Power tilt-and-telescoping steering column with memory: Allows steering column to tilt and move toward or away from the driver to achieve a safe and comfortable distance from the advanced multi-stage front driver air bag, if deployed<br />• Rain Brake Support: Uses the ESC pump to occasionally push brake pads lightly against brake rotors in rainy conditions in order to keep rotors dry<br />• Rain-sensing wipers: A driver convenience feature that automatically senses moisture on the windshield and activates wipers<br />• Ready Alert Braking: Anticipates situations when the driver may initiate an emergency brake stop and uses the ESC pump to set brake pads against rotors in order to decrease the time required for full brake application<br />• Rear Cross Path (RCP): In parking lot situations, this system warns drivers backing out of parking spaces of traffic moving toward their vehicle. It activates any time the vehicle is in Reverse. The driver is notified of vehicle(s) crossing behind the vehicle via illuminated icons on the sideview mirror and with a driver-selected audible chime<br />• Remote (fob) operated windows (front windows – down only): Enable an individual to cool down the vehicle passively by opening front windows remotely<br />• Remote keyless entry: Locks and unlocks doors and turns on interior lamps. If the vehicle is equipped with a security alarm, the remote also arms and disarms that system<br />• Remote start: Conveniently starts the engine and activates key comfort settings based on ambient conditions by using the key fob while maintaining vehicle security<br />• Rollover crash sensing: Senses a rollover and deploys seat belt pretensioners and/or standard full-length side-curtain air bags as needed<br />• Seat belt pretensioners: During a collision, impact sensors initiate front seat belt pretensioners to remove slack in the seat belt system, thereby reducing the forward movement of the occupant’s head and torso<br />• Sentry Key® engine Immobilizer: Utilizes an engine key that has an embedded transponder with a preprogrammed security code to discourage vehicle theft. When the key is inserted into the ignition, the controller sends a random number to the transponder and the engine is allowed to start. If an incorrect key is used, the engine will shut off after a few seconds<br />• Signal mirrors: Signal lamp built into the housing of exterior mirrors allows turn signals to be viewed from the front, as well as the sides and rear of the vehicle in order to alert oncoming traffic and pedestrians<br />• SmartBeam® headlamps: Headlamp system adjusts to ambient light and oncoming traffic to deliver maximum lighting<br />• Standard full-length side-curtain air bags: Extend protection to all outboard front- and rear-seat passengers.

Being the largest in its class, nearly three inches longer than the C-Class and seven longer than the 3 Series sedan. With that increase in length and width and a minor reduction in height (making lower by less than 0.1 inch), the new model has a intergrated, sportier stance and holds the road with a new sense of confidence and enthusiasm.<br /><br />Its new underpinnings are shared with the upcoming S5 and A5 coupes, and an A4 Avant will go on sale in the U.S. at the same time as the sedan. Like the A5/S5, the new A4 has sculpted lines, a more aggressive front end, and a row of LED daytime running lights underlining each headlamp. Thanks to the liberal use of ultra-high-strength steel, the body weighs 10 percent less than last year's, yet is more rigid. The side view is rather familiar-time will tell if this redesign was too conservative, especially compared with the aggressive lines of the new C-Class.<br /><br /><br />Audi A4 interior is completely redesigned, with high-quality materials and clean, attractive design continue to live up to Audi's stellar reputation. Black leather seats and matching black door panels contrasted nicely with patterned brushed aluminum accents. The redesigned center stack is easy to use, and MMI is now a part of the A4's layout -- we've heard it will be standard with the 3.2 (optional) optional. The cabin is larger in every dimension, front and rear seats are now more comfortable, and there's more rear-seat legroom than in the outgoing model. The trunk is bigger -- now 17.0 cubic feet, up from 13.4. Regardless, leather will be standard and should come in a choice of colors. Stereo options will include a choice of Bang & Olufsen stereo systems, including the excellent 14-speaker setup, plus a six-disc CD changer and iPod connectivity. In the cabin are more safety features: six airbags will be standard and rear-side airbags optional.<br /><br />When the A4 goes on sale, it will initially be offered in quattro form only, with one engine and transmission –<br />a new 3.2-liter,<br />265-horsepower V-6 backed by a ZF six-speed automatic.<br /><br />A second engine will follow -- expect an all-new 2.0T four and a manual and/or DSG with quattro as an option. The direct-injection V-6 uses Audi's two-stage valve-lift system, which makes more efficient use of the engine to improve fuel economy by six percent. The A4 gets to 62 mph in an estimated 6.2 seconds when backed by the manual, and the transmission's shifts are quick and easy to control with the steering-wheel-mounted paddles. And, through the reduced weight of the body, reduction in drag (down from a 0.31 Cd to approximately 0.29), and changes to the air conditioner (now 10 percent more powerful and the fuel consumption needed to run it has been reduced by 20 percent), fuel economy has improved.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-86915457475028123512011-03-19T19:18:00.000-07:002011-03-19T19:19:12.751-07:00straight-6 EngineThe straight-6 (also inline-6, I-6, or I6) is an internal combustion engine with six cylinders aligned in a single row. The name slant-6 is sometimes used when the cylinders are at an angle from the vertical.<br /><br />Straight-6 engines have perfect primary and secondary balance and require no balance shaft.<br /><br />Usually a straight-6 was used for engine displacements between about 2.5 and 4.0 L. Sometimes this configuration is used to make smaller engines which tend to be powerful and very smooth running, but also rather expensive to manufacture and physically longer than alternative layouts. The smallest production straight-6 was found in the Benelli 750 sei motorcycle, displacing 747.7 cc. The largest are used in tractor-trailer combinations and some low speed diesels in cargo and passenger ships. These engines have a displacement of 1000 L or more.<br /><br />Straight-6 engines were historically more common than V6s, mainly because the length of such engines was not such a concern in rear wheel drive vehicles but also because V6s (unlike the crossplane V8) were somewhat difficult to make smooth-running. The widespread use of front-wheel-drive and transverse ("east-west") engine configurations in smaller cars saw that the shorter engine length of the V6 became highly desirable, and these days most six-cylinder engines are made in the V configuration.<br /><br /><br /><br />Straight-6 engines in Europe<br /><br />Volvo produced straight-6 engines used in the 960/S90 (RWD) series from 1992~1998. In the following model year, the same engine was further refined for transverse mounting and VVT in the front-wheel drive Volvo S80. A New 3.2-liter straight-6 was introduced for 2007 model years.<br /><br />Audi has never offered straight-6 engines; until the mid-1990s, however, straight-5 gasoline engines were available for most models, some of them turbocharged.<br /><br />Although Mercedes-Benz used to build many straight-6s both as gas and diesel engines, it has recently abandoned the layout and now only engineers V6 engines (they have retained the straight-6 layout for medium duty diesel applications such as the MBE 906).<br /><br />BMW, on the other-hand, is one of the few remaining manufacturers to persist with the straight-6 configuration, making petrol and turbo-diesel engines ranging from 2.0 to 3.2 L in displacement (as of 2005). In 2006, they announced that the upcoming 335i model of their E92 3-series coupé will have a 3.0L twin-turbo straight-6, showing the company's continued dedication to the straight-6 engine configuration.<br /><br />Opel has also used a straight-6 engine in the 1970s until the early 1990s, ranging between 2.5 and 4.0 L. They powered Opel's top of the line models, including the Monza, the Omega and the Commodore.<br /><br />In 1959, Saab had an experimental car with two transverse straight-3 engines bolted together — the Saab Monster.<br /><br /><br />Straight-6 engines in Britain<br /><br />The straight-6 was the archetypal British engine for sports and luxury cars for many years. Rolls-Royce used straight-6 engines until changes in their design made the shorter V8 layout more suitable.<br /><br />Jaguar used them, from 1949 until the mid 1990s in form of the legendary twin-camshaft Jaguar XK6 engine, until, at Ford's insistence, they adopted a V8. Aston Martin used a straight-6 for many years, as did Austin-Healey in their Austin-Healey 3000. MG also used a straight-6 in their MGC.<br /><br />Bristol produced a straight-6 until 1961, based on BMW plans, that was also used in many small manufacturers' cars.<br /><br />The compact Triumph straight-6 powered their high-end saloon and sports cars from the mid 1950s to the mid 1970s.<br /><br />British sports car company TVR has designed its own straight-6, known as the Speed Six, and now uses it exclusively in all of their models.<br /><br />Land Rover used a 2.6L straight-6 from 1967 in certain series Land Rover models.<br /><br /><br />Straight-6 engines in the United States<br /><br />Engines of this type were popular before World War II in mid-range cars. Most manufacturers started building straight-6 engines when cars grew too large for the straight-4.<br /><br />After the war, larger cars required larger engines, and the straight-6 became the base engine model used on economy cars only. The vast majority of American cars during this period had V8s.<br /><br />The Chrysler Corporation had noteworthy slant-6 engines, used in the Plymouth Valiant and Dodge Dart A-body models of the 1960s and 1970s.<br /><br />Another significant straight-6 engine family was introduced by American Motors (AMC) in 1964. These engines were used in a variety of AMC passenger and Jeep utility vehicles. They were also assembled and marketed internationally. Some markets (such as Mexico) built their own specialized versions of this engine. American Motors' straight-6 engine received a number of modifications and was produced continuously (even after Chrysler's buyout of AMC) for 42 years.<br /><br />When cars began to get smaller again in the 1970s, the trend was towards the greater compactness enabled by the V6 layout, and straight-6 engines became rare in American cars except for trucks and vans. Jeeps were an exception to the rule, getting AMC's straight-6 as the base engine option in 1972. These engines continued receive upgrades with an advanced for its time, high-performance 4.0 L option in 1987. Usage of the AMC 4.0 has been declining in Jeep vehicles since the 2002 replacement of the Jeep Cherokee with the Liberty, which features the Chrysler 3.7 L V6 instead. It has declined further since the 2005 introduction of the third generation Jeep Grand Cherokee, which also uses the 3.7 L V6. The last application of the 4.0 was in the 2006 Jeep Wrangler; for 2007 the engine has been replaced with a 3.8 L V6.<br /><br />Ford used a straight-6 in baseline Mustangs and in its other models for many decades. They were also found in F150 pickups until 1997 when they were replaced with a V6.<br /><br />In 2001 General Motors introduced a new family of straight engines, the Atlas, for use in the newly-introduced Chevrolet TrailBlazer/GMC Envoy. The straight-6 was chosen for development because of the desirable operating characteristics of its self balanced design.<br /><br />As far as passenger vehicles are concerned, straight-6 engines might be making a comeback in some larger vehicle types such as trucks and SUVs. Examples include the 5.9 L Cummins Turbo Diesel engine used in Dodge Rams and GM's 4.2L "Vortec 4200". Many big rig trucks also use straight six diesels.<br /><br /><br />Straight-6 engines in Asia<br /><br />The Japanese have used the straight-6 with great success since the 1960s in a wide range of applications, from passenger vehicles, to sports cars, to SUV's. Both Datsun and Toyota were among the first in this trend, though Prince Motors (later acquired by Datsun) and others offered straight-6s in that time too.<br /><br />Toyota started with their M-series engine and later the F, FZ, G, and JZ engines, and Datsun started with their H-series and later the L as well as the famous RB series (used in the Nissan Skyline up until the 'R34' model) engines. Honda built the Honda CBX motorcycle from 1978 till 1981. In 1990's Toyota offered representatives of all 5 families in their vehicles: the G in the Altezza (and others); the M and its replacement, the JZ, in the Toyota Supra (and others); and the F and its replacement, the FZ, in the Land Cruiser. In the 2000's, Toyota's still offers the FZ-series, G-series and the JZ-series engines.<br /><br />In Korea, GM Daewoo's Magnus (sold abroad as the Chevrolet Evanda, Chevrolet Epica or Suzuki Verona) comes with a Daewoo-designed straight-6.<br /><br /><br />Straight-6 engines in Australia<br /><br />Historically, all three manufacturers in Australia used straight-6s. Chrysler had built the Slant 6 in Australia and the unique to Australia Hemi straight-6. These engines were used in the Chrysler Valiant and the Valiant Charger producing up to 320hp. Chrysler no longer owns any factories in Australia.<br /><br />Holden built 161, 186 and 202in³ straight-6s from 1968-1984. They were used in the Kingswood, Torana and in the early Commodores. Modern Commodores use V6s.<br /><br />Ford Australia has been producing straight-6s since 1960 and is the only manufacturer in Australia to still build them. Ford has built 144, 200, 240 and 250in³ engines, with the 240 being called the 3.9l or 4.0l and the 200 being called the 3.3l. They have been used since 1960 in the Falcon, 1970-1982 in the Cortina and from 2004 in the Ford Territory. The current straight-6 engines in the Falcon and Territory are called the Barra.<br /><br />The high-performance division of Ford Australia, Ford Performance Vehicles, produce vehicles equipped with the 4.0 litre DOHC 24-valve turbocharged straight-6 with variable cam timing, which produces 270 kW (362 hp) @ 5250 rpm and 550Nm (406 ft•lbf) @ 2000 - 4250 rpm — the highest level of torque in any Australian production car to date.<br /><br /><br />Diesel straight-6 engines<br /><br />The straight-6 in diesel form with a much larger displacement is commonly used for various industrial applications. These range from various types of heavy equipment to power generation to transit buses or coaches. As with everyday passenger vehicles, the smooth running characteristics of the straight-6 engine is what makes it desirable for industrial use. In addition, a straight-6 engine is mechanically simpler than a V6 or V8. It has only one cylinder head and half as many camshafts as a V engine.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-50613856734185406392011-01-27T19:55:00.000-08:002011-01-27T19:57:07.795-08:00Audi R8 thats power baby<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPp5Uk0oTObNerhorXrYICa8MfAqqTBSTAX-Rii4akY2Yl4o0YiUf0ZMt_1nKxPyrNvI-Mq9AIGzdtrk0wrlHCJedXNswRuNL6VGDWwy2UiPTbU2cClFmDmUz5dcxAZeLHLXLF/s1600/audi-R8-fast-and-furious-723561.jpg"><img style="float: right; margin: 0pt 0pt 10px 10px; cursor: pointer; width: 400px; height: 210px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPp5Uk0oTObNerhorXrYICa8MfAqqTBSTAX-Rii4akY2Yl4o0YiUf0ZMt_1nKxPyrNvI-Mq9AIGzdtrk0wrlHCJedXNswRuNL6VGDWwy2UiPTbU2cClFmDmUz5dcxAZeLHLXLF/s400/audi-R8-fast-and-furious-723561.jpg" alt="" id="BLOGGER_PHOTO_ID_5567080700157515650" border="0" /></a>The Audi R8's well proportioned design screams speed.

The restyled exterior is joined by a new 1.4 i-VTEC engine, which gives the City significantly more power and better performance.<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.452-engines.com/uploaded_images/2009-Honda-City-Interior-755648.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 200px; height: 150px;" src="http://www.452-engines.com/uploaded_images/2009-Honda-City-Interior-755565.jpg" border="0" alt="" /></a><br />The new engine, which is also shared with the new Jazz is fitted with Honda's acclaimed i-VTEC system, which provides excellent performance and flexibility, without compromising fuel economy or emissions. The new engine gives the City 100PS, a healthy 17 PS increase over the previous model. This extra power helps the new City complete the benchmark 0-100 km/h in just 11.8 seconds for the manual version, an improvement of 1.6 seconds. The automatic version hits 100 in 14.7 seconds, almost half a second quicker than before.<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.452-engines.com/uploaded_images/2009-Honda-City-Engine-795497.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 200px; height: 134px;" src="http://www.452-engines.com/uploaded_images/2009-Honda-City-Engine-795494.jpg" border="0" alt="" /></a><br />The manual transmission for City is a modified version of the current gearbox, with carbon synchromesh for smoother changes, improved refinement and a new set of optimised gear ratios. The Automatic transmission is all-new and adds the option to shift gears with steering wheel mounted paddles for the first time. With a sport mode, improved shift logic and ratios the new transmission better compliments the new car's more powerful engine.<br /><br />The all-new model has been further enhanced over its predecessor with a higher quality of materials, improved aesthetics and functionality. Increased storage capacity around the cabin including a bigger glove box improves practicality, while a new design of seats improves passenger and driver comfort.<br /><br />The design changes are complimented by several improvements to the Noise Vibration and Harshness technologies applied to the car. A host of new features in the body, interior, suspension, engine and mountings have been included to bring further refinement to Honda's newest sedan. The NVH enhancements allow customers to make the most of the new audio system which offers iPod connectivity and better sound quality.<br /><br />The New City is based on the platform of the award winning new Honda Jazz, and benefits from the many of the technologies seen in the new hatchback. The longer wheel base gives a significant improvement in interior space as well as the associated ride and handling benefits. Safety performance is also enhanced with the adoption of the ACE Body Structure (Advanced Compatibility Engineering), which better protects occupants of both cars in the event of a collision between vehicles of different heights.<br /><br />The all-new City will go on sale from January in selected markets.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-43618606726983457102009-03-25T05:26:00.000-07:002009-03-25T05:34:42.830-07:00R8 beats the restMany publications were hailing it as the first car to truly be able to beat the Porsche 997 — considered by many[who?] to be one of the best sports cars ever made, and the leader in its class. Initial comparison tests have proven quite positive in this respect; Evo Magazine listed it as a "supercar", compared the R8 to the Porsche 911 Carrera 4S, Aston Martin V8 Vantage, and BMW M6 and after praising the R8's "amazing stability, traction and grip, unparalleled steering accuracy and bite, (and) its uncannily flat and disturbance-free ride", claimed that as a result of "the sublime effortlessness of it all", the Audi is a better sports car. The article concluded that "Audi humbles Porsche. A new dawn starts today".<br /><br />Other publications have also written similar reviews of the Audi beating the Porsche in comparison tests.<br /><br />Top Gear compared the Nissan GT-R to the R8, and remarked that the R8 was "simultaneously less impressive and yet somehow more involving". On the R8 they wrote that "it rewards driver input", calling it "fantastic in a way that will appeal more to true car enthusiasts" but also remarked that it was "much slower" and the GT-R was cheaper. On their test track, the car performed better than a Lamborghini Gallardo and an Aston Martin DB9.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-55839083601559306302009-03-18T22:09:00.000-07:002009-03-18T22:13:38.558-07:00First Audi R8 LMS Delivery<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.452-engines.com/uploaded_images/Audi-R8-GT3-1%5B1%5D-785161.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 200px; height: 133px;" src="http://www.452-engines.com/uploaded_images/Audi-R8-GT3-1%5B1%5D-785158.jpg" alt="" border="0" /></a>Audi Sport Italia receives the Audi R8 LMS with chassis number 101. The symbolic handover of the first customer car was made on Tuesday in the Audi Forum Neckarsulm. Emilio Radaelli, Team Manager of Audi Sport Italia, accepted the R8 LMS from Head of Audi Motorsport Dr. Wolfgang Ullrich.<br /><br />“In the future our new customer sport program represents Audi Sport’s third business field alongside our factory programs in the DTM and in sport prototypes,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich. “2009 is a test and development year during which we aim to collect as much experience as possible with the R8 LMS. We are delighted to be able to do this with teams with which we are familiar and have established a solid partnership over the years.”<br /><br />In the 2009 season, Abt Sportsline, Argo Racing, ORECA, Phoenix Racing and Team Rosberg also trust the new GT3 sports car from AUDI AG. Audi Sport will start the delivery to customers for the 2010 season from fall 2009.<br /><br />The six customer teams plan to race in five European GT3 championships as well as in the 24-hour race at the Nürburgring for which Audi Sport has developed an endurance version of the R8 LMS.<br /><br />Twelve R8 LMS sports cars will be in action in more than 40 events at almost 30 European circuits throughout the 2009 motorsport season. “This allows us to collect a lot of experience which will flow into the development of the R8 LMS,” says Oliver Straube who is responsible for marketing of the R8 LMS at Audi Sport.<br /><br />With the GT3 race version of the R8, Audi Sport developed a racing sports car specifically for use in customer sport with the GT3 race version. Pure “factory” entries are not planned with the R8 LMS.<br /><br />The assembly of the race cars including the body shells is made by quattro GmbH in Heilbronn-Biberach in a factory hall specifically for the customer sport program. The Audi factory in Györ, Hungary, deliver the V10 engines.<br /><br />The new Audi R8 LMS competes in GT3 race series for the first time over the Easter weekend (10 to 13 April).

It will not desert you when you need it most. Here are a few maintenance tips for your car<br /><br /><span style="font-weight: bold;">Check the Engine Oil:</span> To prevent the engine from deterioration, its important that the engine maintains the amount of oil it is programmed to receive. Negligence in doing so will lead to a deteriorating engine performance, meaning you'll get falling mileage.<br /><br /><span style="font-weight: bold;">Make Sure the Lights are working properly: </span>It is important for the lights to be properly focused, for your own and for the oncoming vehicle's safety. Travel on low beam so that it does not obstruct your view instead of helping you along.<br /><br /><span style="font-weight: bold;">Have Suitable Tyre Pressure:</span> The required amount of air pressure needs to be strictly maintained if your car is to get the right mileage and pick-up. Make sure pressure is not to high or you'll shorten the life of your tyres.<br /><br />Radiator Water: If your engine uses water for cooling, take care to ensure that it is regularly changed.<br /><br />Some other tips...<br />Get your vehicle serviced only at authorized service stations<br />Check the engine oil level once every two weeks. Also check the levels of coolant and water in the radiator and battery.<br />Always use genuine spare parts.<br />Avoid accelerating and braking abruptly.<br />Shut up the engine whenever you expect to wait.<br />Drive at a moderate speed of 45-55 km/h to maximize fuel efficiency.<br />Use air-conditioning only when necessary.<br />Avoid riding on the clutch pedal, and release the clutch pedal fully while driving.<br />Maintain optimum air pressure in your tyre to improve mileage.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-51101741642447792372008-08-31T05:30:00.000-07:002008-08-31T05:33:40.577-07:00How To Make your engine perform more efficiently<span style="font-weight: bold;">Try increasing displacement -</span> the more displacement means the more power you’ll because it burns more gas during each revolution of the engine (Not very feul saving). Try making the cylinders bigger or by adding more cylinders. 12 seems to be the limit.<br /><br /><span style="font-weight: bold;">Modify the compression ratio –</span> You can produce more power by increasing compression ratios. The more air/fuel mixture is compressed the more power it will generate, however the more likely it is to spontaneously burst into flame (prior to the spark plug igniting it). Higher octane gasolines prevent this sort of early combustion. High-performance cars generally use high octane gasoline – because the engines use high compression ratios.<br /><br /><span style="font-weight: bold;">Stuff more into each cylinder - </span>you can get more power from the cylinder, if you can cram more air (and therefore fuel) into a cylinder of a given size. Turbo chargers and super chargers pressurize the incoming air to effectively cram more air into a cylinder.<br /><br /><span style="font-weight: bold;">Cool the incoming air –</span> It get pretty hot when compressing air. You would like to have the coolest air possible in the cylinder because the hotter the air is the less it will expand when combustion takes place. An intercooler is a special radiator through which the compressed air passes to cool it off before it enters the cylinder. Therefore many turbo charged and super charged cars have an intercooler.<br /><br /><span style="font-weight: bold;">Let air come in more easily -</span> As a piston moves down in the intake stroke, air resistance can rob power from the engine. Air resistance can be lessened dramatically by putting two intake valves in each cylinder. Some newer cars are also using polished intake manifolds to eliminate air resistance there. Bigger air filters can also improve air flow.<br /><br /><span style="font-weight: bold;">Let exhaust exit more easily -</span> If air resistance makes it hard for exhaust to exit a cylinder, it robs the engine of power. Air resistance can be lessened by adding a second exhaust valve to each cylinder (a car with 2 intake and 2 exhaust values has 4 valves per cylinder, which improves performance - when you hear a car ad tell you the car has 4 cylinders and 16 valves, what the ad is saying is that the engine has four valves per cylinder). If the exhaust pipe is too small or the muffler has a lot of air resistance then this can cause back-pressure which has the same effect. High-performance exhaust systems use headers, big tail pipes and free-flowing mufflers to eliminate back-pressure in the exhaust system. When you hear that a car has "Dual Exhaust", the goal is to improve the flow of exhaust by having two exhaust pipes instead of one.<br /><br /><span style="font-weight: bold;">Try making everything lighter - </span>The lighter the piston, the less energy it takes. Lightweight parts help the engine perform better.

Power getz sent to the front wheels via a continuously variable transmission (CVT), which provides an infinite "gear" ratios that keep the engine in its ideal power band. Not only that it also maximizes fuel economy, with an EPA-estimated 19 mpg city and 26 mpg highway.<br /><br />The Maxima 3.5 SV Sport test car achieved a 0-60-mph time of 6.3 seconds. The potent V6 is felt equally strong, and unlike other CVTs, the Maxima's is well suited to its engine. The CVT can simulate six gear ratios that are controlled via steering-column paddles or the console lever. This mode can be quite fun during aggressive driving thanks to its lightning-quick shift response.<br /><br />A particular bright spot in the generally shining 2009 Nissan Maxima is the wonderfully light and precise steering that should be appreciated by both driving enthusiasts and casual commuters alike. With its combination of low-friction weighting and high feedback, the Maxima's steering can be manipulated with the delicate touch of one's fingertips on the well-formed steering wheel as every nuance of the road is transmitted from tires to skin. This, in combination with a taut chassis derived from the Altima, produces impressive handling that should please all but the most demanding enthusiasts.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-36879093965969321852008-03-14T06:26:00.000-07:002008-07-15T20:42:45.207-07:00Audi R8 Pros And Cons Plus OverviewA high-tech content, unique mechanical layout, and original style making it an exotic for those seeking more than just raw performance.<br /><br /><span style="FONT-WEIGHT: bold">Pros</span><br />The balance of handling ability, ride comfort, high-tech suspension and transmission, beautiful cockpit, an upscale interior design and materials, plus an easy-to-drive nature.<br /><br /><span style="FONT-WEIGHT: bold">Cons</span><br />Couldn't challage the straight-line pace of a Porsche 911 Turbo or Corvette Z06, plus the lack of factory-supplied customizing features.<br /><br /><span style="FONT-WEIGHT: bold">New features for Audi R8 2008</span><br />The 2008 Audi R8 is the first midengine exotic sports car.

Its famous shape has been carefully evolved for the second-generation model, with edgier lines giving it a more up-to-date look. <br /><br />Which engine should you go for? the coupé, has the entry-level 2.0T FSI, not the range-topping 3.2-litre V6, <br /><br />Pumping out 197bhp and 280Nm of torque, using the four-cylinder turbocharged motor. And it's a cracking powerplant. Propelling the Roadster from 0-62mph in only 6.7 seconds and on to 147mph, it's hardly any slower than the 3.2-litre V6. <br /><br />The positive shift of the six-speed manual transmission enhances in-gear throttle response, and overtaking ability is strong. What's more, the addition of twin balancer shafts means the engine is smooth right up to its 7,000rpm red line. It's economical as well, posting a combined fuel consumption figure of 36.2mpg - which compares well with the V6's 27.2mpg. <br /><br />There are further benefits when it comes to handling. All TT Roadsters use lightweight Audi Space Frame technology, meaning that 58 per cent of the body is made from aluminium and 42 per cent is steel. The front-wheel-drive 2.0T FSI is even lighter, tipping the scales at 1,295kg - that's 175kg less than its more powerful brother. <br /><br />Factor in a chassis which is much stiffer than its predecessor's - with no scuttle shake or vibration through the interior mirror - and the result is a machine that is extremely agile and great fun to drive. The new model is much more involving, with direct steering, excellent body control and lots of grip. <br /><br />There is even a fair degree of throttle adjustability, with a mid-corner lift of the accelerator tucking the nose in neatly. Compared to the quattro model, traction suffers a little in the wet, particularly when accelerating out of junctions, but that's the only real negative.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-62926255664739448652007-06-15T23:53:00.000-07:002007-06-15T23:56:04.237-07:002007 Ford Shelby GT<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.452-engines.com/uploaded_images/GT500_quarter-709766.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer;" src="http://www.452-engines.com/uploaded_images/GT500_quarter-709760.jpg" alt="" border="0" /></a>The '07 Shelby GT points back to the original Shelby Mustang GT350.

Such a thing can happen when the engine runs very rich, depositing unspent fuel and particles on the pistons and valves. Similarly, non-smooth metal regions within the piston chamber can cause this same problem, since they can glow red. It has also been suggested that an improperly rated sparkplug can retain heat and cause the same problem.<br /><br /> * A carburetor that does not close entirely can contribute to running once the engine is off, since the extra fuel and oxygen mixture can combust easily in the warm piston chamber. Similarly, hot vaporized oil gases from the engine crankcase can provide ample fuel for dieseling.<br /><br /> * Incorrect timing.<br /><br /> * An engine that runs too hot or too lean may produce an environment conducive to allowing unspent fuel to combust.<br /><br /> * An idle speed that is too fast can leave the engine with too much angular momentum upon shutdown, raising the chances that the engine can turnover and combust more fuel and lock itself into a cycle of continuous running.<br /><br /><br /><span style="font-weight: bold;">Potential fixes</span><br /><br />Items similar to carburetor cleaners and carbon cleaners have been suggested as partial remedies for attempting to clean the piston chambers and valves of engines that run too rich.<br /><br />For those engines that have sharp metallic edges, it has been noted that poorly milled heads and blocks can contribute to this problem, so having the rough spots smoothed may help.<br /><br />For those engines that run too hot or too lean, verify that all mechanisms in place to cool the engine properly function as they should. Replace the thermostat if necessary. Clean the radiator. Verify that all auxiliary fans engage at their proper temperatures, and ensure that the thermostatic sensors on belt driven fans engage as necessary.<br /><br />In the case that there is too much angular momentum, lower the idle speed if possible.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-92136053045225612712007-05-18T16:32:00.000-07:002007-05-18T16:36:56.286-07:002008 Audi TT coupe and convertibleThe redesigned 2008 Audi TT coupe is longer, wider and faster.<br /><br />2008 Audi TT coupe and convertible<br /><br /><span style="font-weight: bold;">Type: </span><br />A rear-wheel drive two-passenger convertible or 2+2 coupe.<br /><br /><span style="font-weight: bold;">Models: </span><br />Coupe (with 2+2 seating); Roadster (two-seater)<br /><br /><span style="font-weight: bold;">Retail price*: </span><br />$35,575 -- $50,000<br /><br /><span style="font-weight: bold;">Engines:</span><br /># 2-liter 4-cylinder turbo, 200 horsepower, 207-pound-feet torque;<br /># 3.2-liter V-6: 250-horsepower, 236-pound-feet torque<br /><br /><span style="font-weight: bold;">Transmission:</span><br /># 2-liter: six-speed automatic with sequential shifting.<br /># 3.2-liter: six-speed automatic with sequential shifting or six-speed manual.<br /><br /><span style="font-weight: bold;">EPA mileage</span><br /><br /># 2-liter:<br />Coupe: 23 mpg / 31 mpg<br />Roadster:<br />22/29<br /><br /># 3.2-liter (both types with automatic transmission):18/24<br /><br /># 3.2-liter (both types with manual transmission): 17/24<br /><br /><span style="font-weight: bold;">Notes: </span><br />Expect a six-speed manual transmission to come with the 2-liter engine in the coming years<br />*Includes shipping<br /><br /><br /><span style="font-weight: bold;">Performance: </span><br />Excellent.

Although petcocks are used in a wide variety of applications, the following passage will describe one of the most common applications of the petcock which is the control of gasoline on a motorcycle engine.<br /><br />Most motorcycles have a fuel petcock valve mounted on or nearby the gas tank to control the supply of gasoline. The petcock typically has three positions: ON, OFF, and RESERVE. The reserve position accesses the bottom portion of the gas tank. The reserve position functionality of the petcock is especially useful on motorcycles because they often don't possess a fuel gauge.<br /><br />When operating a motorcycle the fuel management process often proceeds as follows: Especially when regarding vintage motorcycles the petcock is set to the off position when the motorcycle is not being operated. This is to eliminate fuel overflow and leakage via the carburetor(s). Before starting the engine the petcock is turned to the ON position in order to provide gasoline to the fuel delivery system.<br /><br />While operating the engine there will reach a point at which fuel consumption causes the level of gasoline in the gas tank to fall below that which can be accessed by the petcock in the ON position. At that time continued operation of the engine can be maintained. This operation is achieved by accessing the remaining fuel in the gas tank via rotating the valve in the petcock to the RESERVE position.Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-61693662229761632752007-05-15T10:36:00.000-07:002007-05-15T10:40:55.638-07:00BMW xDrive<div style="text-align: left;">BMW xDrive is BMW's four-wheel drive system that powers the X3, X5 and 2006 and later xd and xi 3 Series and 5 Series models.<br /><br />Instead of a 60-40 (rear-front) power split (which all millennium four-wheel drive BMW's exhibit — 325xi, 330xi, early X5) with power being cut to wheels which lost traction through DSC (Dynamic Stability Control), xDrive allows power to be split between the front and rear axles through use of a multiplate clutch located between the gearbox and the Cardian shaft. This setup allows xDrive vehicles to split power in virtually any way it pleases. If the car felt like it was in a threatening situation (note not an unstable one), xDrive would react immediately, often before the driver ever knew of its intervention, to alleviate traction and control of the vehicle.<br /></div><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.452-engines.com/uploaded_images/800px-BMW325XI_E90-713908.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="http://www.452-engines.com/uploaded_images/800px-BMW325XI_E90-713903.jpg" alt="" border="0" /></a>xDrive is also closely knit with DSC. In the case that wheelspin still occurs while xDrive is or has been shifting power, DSC can brake independent wheels to regain traction. xDrive also helps in cornering. When the vehicle senses that it was about to understeer or oversteer the vehicle can independently cut traction to either of the front wheels or rear wheels to help regain stability and keep the driver on the road.<br /><div style="text-align: left;"><br />xDrive was one of the first technologies used to intervene before the driver was aware that the car was becoming or would become unstable. Its intervention is transparent to the driver.</div>Unknownnoreply@blogger.comtag:blogger.com,1999:blog-34773106.post-49434594306374124922007-05-15T10:31:00.000-07:002007-05-15T10:32:46.331-07:00Unusual four-wheel drive systemsPrompted by a perceived need for a simple, inexpensive all-terrain vehicle for oil exploration in North Africa, the French motor manufacturer Citroën developed the 2CV Sahara. Unlike other 4x4 vehicles which use a conventional transfer case to drive the front and rear axle, the Sahara had two engines, each independently driving a separate axle, with the rear engine facing backwards. The two throttles, clutches and gearchange mechanisms could be linked, so both 12 bhp 425 cc engines could run together, or they could be split and the car driven solely by either engine. Combined with twin fuel tanks and twin batteries (which could be set up to run either or both engines), the redundancy of two separate drive trains meant that they could make it back to civilization even after major mechanical failures. Only around 700 of these cars were built, and only 27 are known to exist today. Enthusiasts have built their own "new" Saharas, by rebuilding a 2CV and fitting the modified engine, gearbox and axle onto a new, strengthened chassis.<br /><br />BMC experimented with a twin-engined Mini Moke in the mid-1960s, but never put it into production.<br /><br />Suzuki Motors introduced the Suzuki Escudo Pikes Peak Edition in 1996. Though actual numbers were never released, this twin-engined vehicle is believed to weigh around 1760 pounds and produce nearly 1000bhp. The engine is a twin-turbo charged 2.0L V6 mated to a sequential 6-speed manual transmission.<br /><br />Nissan Motors has developed a system called E4WD wherein the rear wheels in a car that is normally front-wheel drive are driven by electric motors. This system was introduced in some variants of the Nissan Cube and Tiida.<br /><br />Most recently, DaimlerChrysler's Jeep Division debuted the twin engine, 670 hp Jeep Hurricane concept at the 2005 North American International Auto Show in Detroit. This vehicle has a unique "crab crawl" capability, which allows it to rotate in 360 degrees in place. It also has dual Hemi V8s.Unknownnoreply@blogger.com
