Jaguar XKR-S, 2012

 
 
 
 
 
 Jaguar XKR-S, 2012

Making its debut at the 2011 Geneva Motor Show, the Jaguar XKR-S is the most extreme expression yet of Jaguar's passion for building beautiful, fast cars. For the first time with a series production car, Jaguar gains entry to the exclusive '300kph club' thanks to the effortless performance of the supercharged 5.0-litre AJ-V8 engine. A revised fuelling map means the direct-injection powerplant now produces 550PS and 680Nm of torque. Extensive recalibration has ensured that power delivery and performance are seamless, contributing to a 0-60mph time of 4.2 seconds. The Performance active exhaust encourages and rewards the enthusiastic driver with dramatic, motorsport-inspired aural feedback.

The Jaguar XKR-S is not merely the quickest Jaguar ever but also the most agile, responsive and driver-focused. The pinnacle of the XK range builds on feedback gathered from the supercharged XKR and has been developed to extend the performance parameters of the car. This new harder-edged character allows the enthusiastic driver to explore the outer limits of the car's dynamics without losing the refinement and usability for which Jaguar is famous. The structural integrity of the lightweight aluminium platform allowed the suspension to be reworked with bespoke components for increased stiffness without a commensurate loss in either refinement or Jaguar's legendary ride comfort. A reworked aluminium front suspension knuckle and revised rear geometry are allied to stiffer springs and dampers, lightweight forged alloy wheels and recalibrated steering effort to minimise any response delays and produce a more connected and agile driving experience.

The performance of the Jaguar XKR-S is reflected in both its interior and exterior styling, which feature exclusive new paint colours that reflect Jaguar's racing heritage. As with competition Jaguars of the past, the exterior of the XKR-S adheres to the principle of form following function. In addition to the styling changes and in order for it to achieve 300kph, the XKR-S was the subject of extensive Computational Fluid Dynamics development work. The resulting changes reduced front and rear lift by more than a quarter and optimised lateral aerodynamic stability.

The performance intent of the Jaguar XKR-S is clear from the moment the driver enters the cabin thanks to new cosseting Performance seats with prominent shoulder wings for close support during hard cornering. The seats feature 16-way adjustment, memory and heating functions while a new three-spoke steering wheel provides the perfect interface between car and driver.

Styling
Ian Callum, Design Director, Jaguar Cars: "The styling of this car isn't about image, it's about true performance. Like other iconic Jaguars before it, the styling has been driven by geometry and aerodynamics for genuine design purity. The physics required to achieve 300kph have led the aesthetic; if you don't like the way it looks, you probably won't like the way it drives either."

The first Jaguar designed entirely under the aegis of Design Director Ian Callum, the XK has received awards worldwide for its elegant appearance. Now further styling changes keep the XKR-S at the forefront of modern sports car design. Slimmer, LED headlights, more compact main air intake and vertical side power vent all contribute to a more purposeful front-end appearance. At the rear of the car the famous Jaguar 'Leaper' now takes pride of place in the centre of the bootlid.

The Jaguar XKR-S also required aerodynamic modifications to achieve its 300kph top speed in the unruffled manner expected of a Jaguar and has been designed solely with an eye for purity of line and singularity of purpose. As the XKR-S approaches its top speed, there is a requirement to channel air cleanly over, around and under the car in order to maintain stability and ensure balanced downforce front and rear. An overall reduction in lift of 26 per cent has been achieved.

The necessary revisions were made after extensive Computational Fluid Dynamics work, proven through wind tunnel testing and are unique to this flagship of the XK range. The most dramatic changes have been applied to the front of the car, radically altering its appearance and lending it a more assertive look. A new bumper design features near vertical feature lines running down from the edges of the oval air intake and supporting the new carbon-fibre splitter and lower spoiler. At the extreme edges of the front fenders, vertical slots channel air down the sides of the car and along the wider sills for increased high-speed directional stability.

In order to balance front and rear lift, the Jaguar XKR-S features a separate rear wing, a first for the XK range. This addition, with its carbon-fibre centre section, works in concert with the similarly constructed Venturi structure underneath the rear bumper.

The assertive new appearance of the Jaguar XKR-S is subtly highlighted by some carefully chosen details exclusive to this model. Exterior trim is finished in gloss black, complemented by 20-inch Vulcan lightweight forged alloys in a dark technical finish.

The XKR-S is  in a range of five paint colours, two of which evoke Jaguar's competition heritage: Italian Racing Red and French Racing Blue.

Like the lining of a bespoke suit, the finishing touch is provided by the brake calipers, available in either red or gunmetal and emblazoned with the 'Jaguar' name.

The Performance
Russ Varney, Chief Programme Engineer, XK: "With the XKR-S we have exploited the inherent capabilities of the aluminium architecture to its fullest extent to create a track-capable performance derivative extending all car's attributes and delivering an irresistible 'smile of satisfaction' response from the driver."

Astonishing engines have always formed the strongly beating heart of Jaguar's road and race cars from the record-setting straight-six in the XK120 to the smooth V12 that made the XJ12 the fastest four-door in the world when it was launched.

The AJ-V8 joined this illustrious list from the moment the first one was fired into life but in the Jaguar XKR-S it is presented in its most potent form to date. Now in its third generation and with the addition of supercharging, the all-aluminium quad-cam powerplant delivers not only extreme performance but also tremendous efficiency thanks to the technologies incorporated into it, including spray-guided direct injection (SGDI) and dual independent variable cam timing (DIVCT).

Fuel is delivered directly to the centre of the combustion chambers at a pressure of up to 150bar by the centrally-mounted six-hole spray-guided injection system in order to maximise fuel-air mixing and improve responsiveness, particularly at low speeds. It has also allowed an increase in compression ratio from 9.1:1 to 9.5:1 to improve fuel economy while multiple injections reduce the warm up phase to increase catalyst efficiency and reduce emissions.

Each of the four camshafts features a variable timing system which rather than being controlled by oil pressure, are activated by the positive and negative torques generated by the movement of the intake and outlet valves, allowing for a smaller, more efficient oil pump to be fitted, further reducing fuel consumption. The VCT units respond up to three times faster than previously with actuation rates of more than 150 degrees per second at every point in the speed range, making this the most responsive engine Jaguar has ever built, with no gaps in its power delivery.

Like the car itself, the AJ-V8 features aluminium architecture with the high pressure die-cast lightweight block augmented by cast iron liners and cross-bolted main bearing caps which contribute to refinement to match its power. The four-valve cylinder heads are now constructed from recycled aluminium to reduce the environmental impact of engine manufacture.

Nestling in the 'V' of the cylinders is the Roots-type twin vortex supercharger and its two intercoolers that help provide the XKR-S with such urgent motive power. This sixth-generation forced induction unit is 20 per cent more thermodynamically efficient than its predecessor, while the intercoolers feature their own water-cooling circuit to reduce the temperature of the pressurised air to optimise power and efficiency.

The surfeit of power produced by this system meant that it was a relatively simple matter to liberate an extra 40PS and 55Nm over the standard XKR. Remapping the engine's fuelling characteristics and increasing exhaust gas flow through the use of an active exhaust system has lifted total output of the 5.0-litre V8 is now 550PS and 680Nm, making it the most powerful Jaguar road engine ever made and allowing the Jaguar XKR-S to hit 60mph in 4.2 seconds and breach the magical 300kph barrier with ease.

The Performance active exhaust system that helps provide such spirited performance also produces a thrilling motorsport-inspired soundtrack to aurally reward the enthusiastic driver.

Handling
Mike Cross, Chief Engineer, Vehicle Integrity: "This car encompasses everything a performance Jaguar should be; as capable, precise and thrilling on a wet Welsh B-road as it is at the Nürburgring. Every response delay has been minimised in order to give the car a more connected feel in the manner in which it steers, handles, stops and goes."

Jaguar pioneered the use of aluminium construction for series production cars, exploiting the metal's low mass and high tensile strength to maximise benefits in terms of performance, agility, fuel consumption and emissions.

The platform underpinning the XK range makes the car one of the lightest and most rigid in its class with a kerb weight of 1753kg and torsional stiffness of 28,400 Newtons per degree. This fundamental strength allowed Jaguar's Vehicle Integrity team, led by Mike Cross, to develop the dynamic attributes of the Jaguar XKR-S to the full, without affecting refinement. Every Jaguar achieves an unrivalled mix of sporting appeal and luxurious comfort and the XKR-S is the most driver focused Jaguar ever made.

Taking the solid foundation of the aluminium architecture as a starting point, both front and rear suspension systems have been upgraded. The double wishbone front suspension has been comprehensively revised with a new aluminium steering knuckle that significantly increases camber and castor stiffness by 0.13 degrees per Kilonewton to transform the accuracy and weighting of the steering for greater levels of connection, feedback and precision. The Active Differential Control has been reprogrammed to reduce steering sensitivity at the very high speeds of which the car is capable, increasing stability and driver control.

Rear suspension geometry has been revised with rear wheel steer optimised for maximum agility while spring rates have been increased at both ends of the car by 28 per cent. Bespoke software for Jaguar's Adaptive Damping has been written for the Jaguar XKR-S, ensuring both total body control and maximum traction and grip.

Wheel sizes have been increased with the unique lightweight forged Vulcan 20-inch alloys now having a width of nine inches at the front and 10.5-inches at the rear for greater precision and grip. The new wheels wear Pirelli P Zero tyres measuring 255/35 R20 at the front, 295/35 R20 at the rear. This combination has reduced overall unsprung mass by 4.8kg with a commensurate improvement in handling and dynamism.

The Dynamic Stability Control System has been reworked to maximise the benefit of these wider tyres. In Trac DSC mode this utilises specific traction, stability and eDiff settings to alter slip thresholds, differential torque distribution and intervention levels to allow the experienced driver to explore the outer edges of the performance and handling envelope.

The XKR-S is equipped as standard with Jaguar's High Performance Braking System. Lighter and more powerful, this features cast iron and part aluminium monobloc calipers for a combination of power, stability and feel. The brake discs - measuring 380mm at the front and 376mm at the rear - are internally ventilated to provide repeated, fade-free stopping power. In combination with pad surface increases of 44 per cent front and 31 per cent rear the system provides total security and confidence on both road and track. Stopping distance from 124mph has been improved by 2.7 per cent over the already impressive XKR.

The end result is a car that captures the essential duality that is a characteristic of every great Jaguar; capable of transporting the driver to the fabled Nürburgring in total comfort and hushed silence, and yet still able to deliver a sub-eight minute lap time and then return home with total ease.

Interior
The cabin of any Jaguar is always a uniquely special place in which to spend time and the XKR-S meets all expectations from the moment the driver enters to be greeted by the red Start button pulsing like a heartbeat. When pressed, the engine fires with an rich, deep reverberation and the Jaguar Drive Selector rises from the centre console as a point of first contact to begin the process of bonding man with machine.

The interior of the Jaguar XKR-S has been subtly refreshed with a host of new trim materials including ebony soft-feel paint for the switches and gloss black finish to the centre console. The model will also be exclusively available with a Dark Linear Aluminium finish as an option to the wood veneers.

A new leather-wrapped, multi-function steering wheel has also been added, providing a beautiful, tactile interface between car and driver as do the bright, Jaguar-embossed, stainless steel pedals.

Exclusive to the Jaguar XKR-S are the new Performance front seats with an integrated head restraints and increased lateral and squab support to hold driver and passenger securely and comfortably in place during the high speed cornering of which this car is capable. The 16-way adjustment of squab, cushion, lumbar and bolster elements is supplemented by memory and heating functions.

The sense of occasion offered when driving the Jaguar XKR-S will be heightened by the new carbon leather accents covering the seats, featuring unique contrast micro-piping and stitching combinations in Reims Blue, Red and Ivory. Duotone combinations of Charcoal with Tan and Charcoal with Red are also available.

Bugatti Veyron Fbg par Hermes, 2009

 
 
 
 
  •  Bugatti Veyron Fbg par Hermes, 2009

The unique version of the Bugatti Veyron Fbg par Hermès was first launched in Geneva in complimentary tones of ebony and étoupe and ebony and brick. In order to give the customer a wider range of options Hermès and Bugatti have developped four new colours schemes in line with the heritage and the values of the two houses. Therefore, the Bugatti Veyron Fbg par Hermès is now also available in these exclusive combinations : "indigo blue and vermilion", "indigo blue and lime green", "black and garance red" and "Prussian blue and blue jean".

The Bugatti Veyron Fbg par Hermès associates Bugatti's technical performance with the expertise of Hermès and its craftsmen. In partnership with Hermès, designer Gabriele Pezzini has married the distinctive Hermès style to the legendary Bugatti Veyron 16.4, magnifying the car's personality.
This remarkable car features an array of exceptional characteristics: the innovative alliance of a technologically advanced engine, delivering 1001 horsepower, with an understated yet uncompromising silhouette reflecting the high performance capacities of state-of-the-art engineering and design, and above all, the pleasure these inspire in every Bugatti owner.

The fascination exerted by this sports coupé, capable of reaching 407 km/h, is due in large part to its unique alliance of the very finest motor-racing technology with comfortable handling for everyday driving.

The 16-cylinder "W" configuration engine is fed by four turbochargers and features 64 valves, generating 1001 horsepower at 6000 rpm. The engine draws on its 8-litre displacement to deliver a maximum torque of 1250 Newton-metres between 2200 and 5500 rpm. With full-time all-wheel drive, the car's phenomenal power produces breath-takingly dynamic handling, with acceleration from 0 to 100 km/h in a mere 2.5 seconds. The Bugatti Veyron 16.4 benefits from aeronautical and aerospace technologies, making it the fastest production car ever made. The car also features a braking system designed to deliver unprecedented powers of deceleration, establishing a new industry benchmark. The carbon-fibre discs provide brake pressure of up to 180 bars, combined with eight-piston monobloc callipers and titanium pistons fitted with fine steel heads and ceramic heat protectors. Apply the brakes at speeds above 200 km/h, and the rear wing acts as an airbrake, positioning itself at an angle of 113 degrees in less than 0.4 seconds, augmenting the Bugatti Veyron's already impressive stopping power. The airbrake increases negative lift at the rear of the car to 300 kg, enhancing the braking torque on the rear axle. At 400 km/h, emergency braking will bring the sports car to a complete halt in less than 10 seconds.

This, the world's most fascinating car, has pushed back the limits of physical engineering to offer a completely new sensation for driver and passenger alike. But it has also adopted a radically different stance to that of other sports cars: its features and finish are sure to impress the most demanding clientele. Hermès and designer Gabriele Pezzini have lavished attention on the interior and exterior of this exceptional car, to create the new Bugatti Veyron 16.4: the Bugatti Veyron Fbg par Hermès.

The HARMONIOUS DESIGN, INSIDE AND OUT
The official name of the highly exclusive Bugatti Veyron Fbg par Hermès refers to the historic Hermès headquarters on the Rue du Faubourg Saint-Honoré, in the heart of Paris's eight arrondissement: the "Fbg" appellation evokes the house's "faubourg" address.
With the Bugatti Veyron Fbg par Hermès, the exacting standards of Émile Hermès and Ettore Bugatti come together for the first time, in an exceptional collaboration: the culmination of their extreme attention to aesthetic and technological quality and performance.

Gabriele Pezzini has reinterpreted Bugatti's traditional two-toned carriage work, fostering a fluid, harmonious transition between the car's exterior and interior design. The colour of the hood extends to the interior of the cockpit, and re-emerges behind, at the level of the rear wing.
As a tribute to the celebrated 1924 Bugatti Type 35, undoubtedly the most famous of all time, thanks to its many successes on the racetrack, the new Bugatti Veyron Fbg par Hermès features eight-spoked wheels in polished aluminium, central butterfly wheel locks branded with the letter H, and air vents around the rims reproducing the characteristics appearance of Hermès saddle-stitching. The horseshoe radiator grille, and the lateral ventilation grilles flanking it, are made from lightweight alloys with a design of interlocking H's evoking the Hermès "signature".

A REFINED FORMAL VOCABULARY
The inner surfaces of the Bugatti Veyron Fbg par Hermès have been designed and sheathed in bull calfskin by the Hermès workshops in Paris. The care and attention to detail observe an extremely refined, minimalist formal vocabulary, reflecting the tradition of the very first Bugattis and the fundamental design principles of the house of Hermès. The door handles echo the fluid forms of handles on Hermès travel bags and luggage.

And the dashboard, traditionally finished in brushed aluminium, is here clad entirely in bull calfskin. Passengers aboard the Bugatti Veyron Fbg par Hermès will find a dashboard glove compartment designed to hold a selection of small travel accessories and a zipped Hermès wallet. Both seats are covered in two-toned bull calfskin, and the panel separating the cockpit from the central rear engine - traditionally made of carbon fibre- is covered in the same fine leather. The leather-lined trunk holds a specially-fitted "Toile H" and leather case, hand-made by the craftmen from the Hermès workshops.

Koenigsegg CCX, 2006

 
 
 
  •  Koenigsegg CCX, 2006

The CCX is the latest iteration of the Koenigsegg CC family. The CCX is in many aspects a new car since it has been re-engineered to comply with the US regulation and market demands. Still, it has been a key issue for the Koenigsegg Team to keep the distinctive and record breaking CC shape. Koenigsegg believes it is important to avoid trends and instead hone the aerodynamic shape of the CC range for the future, only enhancing its unique look and appearance with tighter lines and a more aggressive stance. At Koenigsegg they also believe in continuity. A new Koenigsegg shall show clear lineage from its predecessor and shall not follow any other design trends - but enhance its already proven concept and shape to perfection.

Body & Interior
The CCX features a completely new set of body and interior parts. The new body incorporates a new front bumper design, engineered to function well in the stringent 2.5 mph bumper test, including enhanced brake cooling, fog lamps and US side position lights. The front lamps have been slightly redesigned to suit the new bumper line.

There is a new scoop on the front bonnet acting as a larger fresh air-intake for the occupants and new air vents have been added behind the front wheels in order to further evacuate air from the cockpit. The frontal shape revisions now allow for effective track use options to be added.

The side rocker panels feature side skirts in order to further enhance downforce by increasing underbody area. The new exterior of the car has been created using the industry leading Icem Surf CAD software, guaranteeing a perfect fit and finish as well as optimal highlights.

The car is 88 mm longer in order to comply with the US rear impact regulations and in order to free up space around the rear muffler. The rear clamshell now features a glass window over the new CCX engine, clearly showing off the bespoke and unique Koenigsegg Block casting. The mufflers have received improved cooling, by incorporating grill vents above in the clamshell. The number plate area is now adapted to suit both US and Euro size number plates.

Space
There is a further 50 mm in headroom, making the CCX the most spacious super car on the market, truly considering the taller drivers needs. Koenigsegg believes to have found a unique market niche by enabling really tall drivers to fit well inside the car, still with its highest point only 1120 mm above the tarmac.

Seats
In corporation with Sparco, and Koenigsegg test driver Loris Bicocchi, Koenigsegg has developed a new seat design for the CCX. The structure of the seat are still carbon fiber, but now feature fully padded front surface and a tilting backrest. The striking and very comfortable Tempur padded CCR seats can still be fitted in the CCX on special order.

Wheels / Brakes
The optimal ceramic 382 mm front discs are coupled to 8 piston calipers and in the rear the 362 mm size is retained with 6 piston calipers. The optional industry first carbon fiber wheels save another 3 kg per wheel compared to the already lightweight magnesium wheels that comes as standard. The ceramic discs save another 2 kg per wheel, giving the Koenigsegg CCX lower unsprung weight than any other super car.

Koenigsegg now also offers the ceramic disc and carbon wheel upgrade to all previous Koenigsegg models.

Aerodynamic Enhancement
Between the raised speedster humps there is a new type of vortex generator originally conceived and patented by Torbjörn Gustavsson at Vortaflow and implemented as a Ram Air engine booster by Christian Koenigsegg on the CCX. Due to the fact that there is a fresh air engine intake right below the rear window, the vortex generator redirects the air directly into the air intake and thereby creating a positive pressure in the air box. To normally obtain this phenomenon in a mid engine car a roof scoop is required, increasing frontal area. In the case of the CCX, the small frontal area can still be kept and rearward visibility is unaffected, even though it has now got true ram air intake over its mid mounted engine.

Electronics
The CCX now features, wholly digital, intelligent fuse and relay unit. This means that there are not physical fuses or relays as such. The unit is programmable and is can-bus connected to a display unit which sends crucial information to the driver. The main advantages of this system are its reliability, light weight, small physical size, programmability and direct information to the driver. The system is prepared for future upgrades and functions.

Unique Koenigsegg Engine
The engine in the CCX retains the incredible performance and power of the CCR engine, while running on US 91 octane fuel and complying with California emission regulations. In order to reach this challenging goal, extensive rework had to be done to emission related items, such as new cylinder heads with larger valve area and more optimally flowing cylinder head ports. Dual smaller injectors per cylinder were integrated, as well as new camshafts, a new carbon fiber individual runner intake plenum, a new engine management system, updated fuel and EVAP system. New exhaust system where the catalytic converters are moved closer to the engine for earlier light-off time. A returnless fuel system has also been implemented with pumps integrated into the new fuel tank. All in all, a heavy rework in order to retain the unique performance of the CCX engine and at the same time comply with the strictest emission regulations in the world.

The new and cleaner CCX engine also incorporates the first engine block design that is specifically created and cast for Koenigsegg, with the Koenigsegg shield embossed in the casting on both left and right side of the engine block. The new block design is an all aluminum construction made out of 356 aluminum with T7 heat treat that has undergone a High Intensity Pressure process in order to further enhance block integrity as well as cylinder bore chill during casting. The new block reaffirms the future development of Koenigsegg engines and makes Koenigsegg stand out among low volume supercar manufacturers, due to the fact that Koenigsegg engineer the engine completely in house in combination with the fact that it is also built, assembled, and dyno tested in the Koenigsegg production plant. The Koenigsegg Engineers also incorporated the most powerful internal piston coolers in the industry - bringing down the piston temperature, by as much as 80% more than competing systems, which was a must in order to run high cylinder pressure with 91 octane fuel.

Jeep Wrangler, 2012

 
 
 
 
 
 
 
 
  •  Jeep Wrangler, 2012

Jeep introduces the all-new 3.6-liter Pentastar V-6 petrol engine that  equipped on the 2012 Jeep Wrangler and Jeep Wrangler Unlimited. 3.6-liter V-6 powertrain provides more fuel efficiency, improved on-road driving dynamics and refinement, more power and more torque. Petrol powertrain now adds upgraded automatic transmission for refined shifting and greater performance. Dramatically improved on-road performance combines with even more off-road prowess. New petrol engine joins 2.8-liter turbo diesel engine for European lineup.

In Europe, the all-new 3.6-liter petrol powertrain introduced on Jeep Wrangler and Jeep Wrangler Unlimited Sport, Sahara and Rubicon trim levels starting November 2011.

3.6-liter Pentastar V-6 Engine
Compact and lightweight, the all-aluminum 3.6-liter Pentastar V-6 engine is more than 40 kg (90 lbs) lighter than the previous 3.8-liter V-6 engine that was constructed with a cast-iron block. The Pentastar engine is extremely quiet, constructed with a high-pressure, die-cast aluminum block fitted with cast-iron bore liners and aluminum cylinder heads. The engine also has been designed to meet all known future worldwide emission standards and is currently Euro 5 certified.

The 3.6-liter V-6 engine is manufactured at the Trenton engine plant in Michigan (USA).

Transmissions
The A580 automatic transmission benefits Jeep Wrangler as much as the new petrol engine, with more refined shifting and gear selection. By increasing the number of speeds, the transmission allows the engine to operate in a more efficient RPM range, which helps increase fuel economy. More speeds also enable the engine to remain in the torque curve, increasing acceleration. The new Wrangler (two-door) boasts a 37-percent improvement in 0 - 100 km/h time, which is now 8.1 seconds. Also, a lower first-gear ratio in the new automatic transmission gives the Wrangler more off-road capability via a lower overall crawl ratio.

Electronic Range Select is standard for all automatic-equipped Jeep Wrangler models. The electronic stability control (ESC) also has been optimized to perform effortlessly with the new 3.6-liter V-6 engine.

Along with the proven NSG 370 six-speed manual transmission, engineered for the newest Jeep Wrangler are a new clutch housing, flywheel and long-travel damper clutch. The improvements are a result of the adaptation of the transmission to the 3.6-liter V-6 engine.
The five-speed automatic transmission is produced in Kokomo, Indiana (ITP2), and the six-speed manual transmission is produced in Gaggenau, Germany.

Engineering
Jeep Wrangler delivers unmatched off-road capability with legendary four-wheel drive and is produced with more than seven decades of 4x4 engineering experience behind it. Wrangler continues to offer a body-on-frame design, front and rear five-link suspension system, live axles and electronic lockers.

Jeep Wrangler now offers a choice of two transmissions: a six-speed manual and a five-speed automatic gearbox.

Along with a new powertrain, Jeep engineers have thoroughly optimized ride and sound characteristics of the Jeep Wrangler's body-on-frame design. New motor and transmission adaptations and revised suspension calibrations contribute to overall improvements that are immediately evident both on- and off-road.

The interior sound quality is greatly improved through refinements in the powertrain mounting system, noise damping in the firewall and the inclusion of the first Jeep Wrangler engine cover to effectively isolate the cabin from noises emulating from the engine and road surfaces.

On the outside, engine noise is barely perceptible at idle. With the new 3.6-liter V-6 engine, all accessories are mounted directly to the engine with no accessory brackets. This helps ensure that all accessories, including the power steering pump, alternator and air conditioning compressor, are anchored firmly and less susceptible to vibration and noise.
Shocks have also been retuned and are designed for optimum balance between advanced on-road handling and rugged off-road capability.

Axles and Transfer Cases
The Jeep Wrangler is now available with more axle gear ratios, allowing customers to optimize fuel economy and/or vehicle capability. Wrangler is available with 3.21, 3.73 or 4.10 ratios depending on model. Also, Jeep Wrangler offers towing capability up to 2,500 kg.

The capable driveline of the Sport and Sahara models includes a Dana 30 front axle and Dana 44 rear axle. The Command-Trac® NV241 part-time, two-speed transfer case features a 2.72:1 low-range gear ratio.

The Rubicon model features heavy-duty Dana 44 front and rear axles and the Rock-Trac® NV241 two-speed transfer case with a 4.0:1 low-range gear ratio. Rubicon also includes electric front and rear locking differentials and disconnecting front sway bar, taking Jeep Wrangler to the highest level of capability.

2.8-liter CRD Engine
The all-new 3.6-liter V-6 engine joins the new 2.8-liter turbo diesel engine with fuel-saving Stop/Start technology. The diesel engine provides power of 200 hp DIN (147 kW), a 13-percent improvement over the prior 2.8-liter diesel engine. Torque for the engine comes in at 410 N•m (302 lb-ft) with its six-speed manual transmission and 460 N•m (339 lb-ft) with its five-speed automatic transmission.

Jeep Wrangler's diesel engine, when paired with the manual transmission, incorporates Stop/Start technology - the first application of this technology on a Chrysler Group vehicle. Stop/Start improves fuel efficiency and reduces CO2 emissions by managing the amount of time the engine runs. With Stop/Start, the engine is shut off when the vehicle is stopped, the shift gear is in Neutral and the clutch is released. The engine then restarts automatically when the clutch pedal is depressed. Drivers can deactivate the technology via a button on the dashboard, and an icon displays in the instrument panel to indicate the Stop/Start status.
