 Jeep Grand Cherokee SRT, 2014

Jeep Grand Cherokee SRT owners have come to expect - and appreciate - a vehicle that is powerful and refined, luxurious and functional, muscular and stylish. For 2014, Grand Cherokee SRT checks all of those boxes - while also delivering unexpected delights.

Enhancements for the 2014 model year include an all-new, fully electronic eight-speed automatic transmission that delivers improved fuel economy, significantly improved towing capacity, hardware and software revisions that further heighten Jeep Grand Cherokee SRT's fun-to-drive factor during a daily commute or for more spirited driving on the race track.

Outside, the new 2014 Jeep Grand Cherokee SRT sports styling that is even more aggressive than the previous model. Design enhancements for 2014 include a new signature LED character lamp treatment, a brawnier grille, a new, one-touch liftgate and a new rear spoiler.

Inside, Jeep Grand Cherokee SRT customers are treated to a new 8.4-inch touchscreen that displays a wealth of SRT-exclusive Performance Pages data. A new launch control button is situated behind the new T-handle shifter on the center console, and a redesigned SRT-exclusive three-spoke, heated steering wheel with more ergonomically efficient paddle shifters, features a host of comfort, convenience and connectivity controls.

Awe-inspiring powertrain
For 2014, Grand Cherokee SRT owners get three additional gears from their transmission: an all-new 8HP70 eight-speed automatic. Fully electronic, it features on-the-fly shift-map changing.

For an even sportier, more driver-controlled experience, the 8HP70 eight-speed transmission can be manually shifted using newly redesigned, more pronounced, ergonomically efficient steering-wheel paddle controls.

The Jeep Grand Cherokee SRT features a new Eco Mode for 2014 that optimizes the new transmission's shift schedule and extends the range of Fuel Saver Technology, which deactivates four cylinders when conditions allow. A button on the center stack allows driver's to engage Eco Mode for improved fuel economy.

The new eight-speed automatic transmission is specifically engineered to optimize shift quality and shift points for fuel economy, performance and drivability. The intelligent software takes into account variables including engine torque gradients, kick-down events, longitudinal and lateral acceleration, grade changes, friction detection and downshift detection to determine the appropriate shift map.

Additional parameters integrated into the control strategy include vehicle speed control, electronic stability control interaction and temperature. The result is automatic shifting that is ideally attuned to the performance requirements of almost any driving demand.

The new transmission is mated to the proven and powerful 6.4-liter HEMI® V-8 with Fuel Saver Technology delivering 470 horsepower (351 kW) at 6,000 rpm and 465 lb.-ft. (630 N•m) of torque at 4,300 rpm and helps deliver greatly enhanced towing performance of 7,200 pounds - a 44-percent improvement over the 5,000-lb. towing capacity from the previous model.

For 2014, the new electronic T-handle shifter provides the flexibility for drivers to choose a transmission shift schedule independent from the Selec-Track system. Drive and Sport shifting can be selected via the T-handle with no effect on the chosen suspension, stability control and driveline torque split settings.

Also new for 2014 is a launch control system that mimics a professional driver's inputs to optimize Jeep Grand Cherokee SRT's performance by bringing engine, transmission, driveline, stability control, and suspension in line for a textbook launch. Controlled by a button behind the new T-handle shifter on the center console, the result is improved and more consistent straight-line acceleration. The performance experience of the 2014 Grand Cherokee SRT is further accentuated by a change in transfer case proportioning and dynamic controls for the Selec-Track system when the vehicle is in Track Mode. When this mode is selected, 70 percent of the engine's torque is delivered to the rear wheels for a more pronounced rear-wheel-drive experience. Jeep Grand Cherokee SRT drivers will notice a vehicle that is more responsive from mid-corner to exit.

Outstanding ride, handling and capability
The Grand Cherokee SRT rides on a short- and long-arm (SLA) independent front suspension with coil springs, Bilstein adaptive damping suspension (ADS), upper- and lower-control arms ("A" arms), and a stabilizer bar.

The rear suspension is a multi-link design with coil spring, Bilstein ADS, aluminum lower control arm, independent upper links (tension and camber), plus a separate toe link, and a stabilizer bar.

Software improvements to the retuned Selec-Track system further distinguish the five dynamic modes: Auto, Sport, Tow, Track, and Snow, enabling drivers to choose a vehicle setting that more ideally meets their requirements and ambient conditions. Drivers will find the torque split change in Track Mode provides a vehicle that is more responsive from mid-corner to exit and one that delivers faster lap times at their favorite track.

Benchmark braking
The new 2014 Grand Cherokee SRT delivers excellent braking performance, requiring only 116 feet to come to a full stop from 60 miles per hour (mph). Credit belongs to red-painted, Brembo six-piston (front) and four-piston (rear) calipers, and vented rotors at all four corners measuring 15 inches (front) and 13.8 inches (rear).

The Design
Starting with the performance-oriented and functional designs from the SRT (Street and Racing Technology) brand, the 2014 Jeep Grand Cherokee SRT model builds on that success with new exterior and interior styling cues that convey an even higher level of opulence and power.

Aggressive and functional exterior
The blending of aggressive, upscale and functional styling of the 2014 Jeep Grand Cherokee SRT is readily apparent up front, where the signature seven-slot upper grille with black screen insert has been shortened and is flanked by slimmer, adaptive, bi-xenon headlamps that are surrounded by a signature LED character lamp treatment. The iconic Jeep grille itself is larger, and the headlamps feature a unique black background to distinguish the new SRT model from other Jeep Grand Cherokee models, while further accenting their jewel-like appearance.

The new styling enhancements also enabled SRT designers to incorporate the headlamp washers into the headlamp housing for the first time - rather than on the bumper - for a cleaner, more functional appearance.

New, five-spoke 20-inch "Goliath" wheels with polished finish are standard and ride on standard Pirelli 295/45ZR20 Scorpion Verde all-season tires or available Pirelli P Zero Three-season tires. Available split five-spoke, 20-inch forged aluminum wheels feature the "Spider Monkey" design in Satin Carbon or SRT-exclusive Black Vapor Chrome finishes.

A new Grand Cherokee badge along the vehicle's sides feature a more distinct, more pronounced font.

The front light treatment of the new 2014 Grand Cherokee SRT is mirrored in back for a cohesive styling appearance and features larger tail lamps with signature LED lighting. To further emphasize the performance heritage of the SRT design, the tail lamps feature a black surround, creating the illusion of floating lamps.

Not an illusion is the all-new, more aerodynamically efficient, rear spoiler integrated into the all-new liftgate.

The new, one-touch liftgate delivers improved customer convenience, and features a new SRT badge that no longer carries the engine cylinder number reference. Rather than relying on a manual lever, the liftgate is operated electronically with the push of a button. For 2014, the flipper glass has been eliminated - greatly enhancing rearward visibility and reducing weight.

Standard 4-inch dual exhaust tips integrated into the lower fascia deliver the throaty exhaust note Jeep Grand Cherokee SRT enthusiasts expect from their vehicle and complete the rear styling cues.

The 2014 Grand Cherokee SRT will be available in the following exterior colors: Billet Silver Metallic Clear Coat, Bright White Clear Coat, Brilliant Black Crystal Pearl Coat, Deep Cherry Red Pearl Coat, Granite Crystal Pearl Coat, Maximum Steel Metallic Clear Coat and Redline Pearl Clear Coat.

Race-inspired and high-performance interior
The 2014 Grand Cherokee SRT delivers an interior that is opulent, functional and ideally suited for daily drives or more spirited performance driving on the track.

A new Uconnect 8.4AN touchscreen takes center stage - literally - and displays a wealth of information including the SRT-exclusive Performance Pages, which cite recent track times, lateral acceleration, 0-60 miles per hour (mph) times and much more. These readouts are displayed in full-color and can now be shared with other SRT enthusiasts via a built-in 3G connection.

On the center console, drivers will find a new T-handle shifter for the new eight-speed transmission that allows the driver to select between Drive and Sport shift schedules. Wrapped in grained leather, this advanced shifter further reinforces the brand's street and racing heritage. Behind the shifter is new launch control button highlighted by a color graphic - similar to the "Christmas tree"-type staging lights from the drag strip.

The standard, SRT-exclusive, leather-wrapped and heated steering wheel with a flat bottom is redesigned with a bevy of new comfort, convenience and connectivity controls and more pronounced and ergonomically efficient paddle shifters.

The new steering wheel is designed and positioned to provide optimal view of the new gauge cluster that now features a 7-inch full-color, customizable instrument display. This new screen allows drivers to select from a multitude of layout and information to be shown in the center of the gauge cluster.

True carbon fiber trim accent sweeps across the driver's door, instrument panel and front passenger door.

The available 825-watt, 19-speaker premium SRT performance audio surround-sound system from Harman Kardon offers world premier innovation, featuring a 32-volt tracking power supply (TPS) 12-channel Class D amplifier that delivers outstanding acoustics and brings multi-dimensional, quality sound for all interior occupants.

Green Edge speaker and amplifier technology offers superior sound quality and high sound pressure level outputs with minimum energy consumption. Green Edge amplifiers alone outperform traditional amplifier efficiency by up to 55 percent, representing a net efficiency of more than 90 percent in some cases. The speakers are tuned for maximum efficiency and perfectly matched to the amplifier output.

The system's 19 Green Edge high-efficiency speakers include nine tweeters, five mid-range speakers, two mid-woofers and three subwoofers located throughout the interior.

The 2014 Grand Cherokee SRT Laguna leather interior is available in two distinctive colors: Torque (black) and a new Sepia combination.

Available as part of the Sepia interior combination, a black Dynamica headliner and black pillars further accentuate SRT's upscale interior appearance.

Enhanced security, convenience and occupant safety
Uconnect Access is all-new to the Jeep Grand Cherokee SRT. Enabled by embedded cellular technology, the system affords direct communication with local 9-1-1 service personnel at the touch of a button - no waiting for go-between call-center operators.

In addition, the 2014 Grand Cherokee SRT showcases advanced safety features from Forward Collision Warning - which alerts the driver to rapidly approaching traffic - to Blind-spot Monitoring and Rear Cross Path detection, which aid drivers when changing lanes or in parking-lot situations.

The second model in Jaguar's ultra-high performance R-S range, the Jaguar XFR-S joins its XKR-S sibling in the exclusive 300km/h club and is a vivid expression of Jaguar's longstanding and legendary sports saloon lineage.

The Jaguar XFR-S incorporates engineering features from both the XKR-S and the all-new F-Type two-seater sports car to create the most driver-focused, agile and responsive iteration of Jaguar's award-winning XF saloon range. The Jaguar XFR-S has been developed by Jaguar Land Rover's specialist ETO division - its bespoke powertrain, chassis and body enhancements enabling it to push the performance boundaries.

Electrifying performance is provided by the 5.0-litre supercharged V8 petrol engine which now boasts 550PS and 680Nm - up 40PS and 55Nm respectively over its XFR installation. The increases have been achieved through revisions to the engine management system and optimisation of the flow of air both into and out of the engine.

Fitted with an eight-speed transmission incorporating Jaguar's 'Quickshift' technology (developed for the F-Type), the increase in engine output allows the Jaguar XFR-S to accelerate to 60mph in 4.4 seconds (0-100km/h in 4.6 seconds) and on to an electronically limited top speed of 186mph (300km/h).

Airflow has been carefully managed in order to both allow the engine to operate at peak efficiency and let the car cleave the air cleanly and safely. The resulting body changes have created a distinctively assertive appearance, beginning with the deeper front bumper with its larger lower air intakes, vertical vanes and carbon fibre front splitter.

Deeper sills and unique 'aero-blades' ensure a clean passage of air along the side of the car and on to the deeper rear bumper sides while a carbon fibre rear diffuser between the signature quad tailpipes extends underneath the rear of the Jaguar XFR-S to reduce lift. It is aided in this by a bootlid mounted spoiler, two designs being available. Overall lift is reduced by 68%.

The unique 20-inch lightweight forged alloy 'Varuna' wheels are wider front and rear and are shod with specially developed Pirelli rubber, giving the Jaguar XFR-S a more muscular stance and increasing its grip and stability. Allied to this are extensive suspension revisions which serve to increase lateral suspension stiffness by 30% for greater steering precision and responsiveness.

Revisions to both spring rates and the adaptive damper tune increase the feeling of connectivity with the road surface, providing confidence-inspiring handling and a supple, controlled ride. Recalibrated active electronic differential and Dynamic Stability Control settings allow the enthusiastic driver to make the most of the huge potential of the Jaguar XFR-S.

The car's intent is underlined by the technical palette of materials used on the interior. This includes carbon leather on the seat bolsters and arm rests and a Dark Aluminium fascia, both of which are exclusive to the R-S range. Providing a further unique touch are a choice of contrasting colour stitching and micro-piping which can be matched to the exterior paint scheme.

Powertrain - 5.0-litre supercharged V8
The XFR-S features Jaguar's acclaimed 5.0-litre supercharged V8 petrol engine in its most potent form matched to an eight-speed transmission with Quickshift functionality. This all-new combination provides a visceral blend of vivid acceleration, driver involvement and control plus entry to the exclusive 300km/h (186mph) club of ultra-high performance cars.

"The XFR-S is a very harmonious product in the way it looks, the way it handles and the way the powertrain responds. The car has instant response to any driver input and as a result feels connected from the outset." Tim Clark, Technical Specialist for Performance and Driveability Attributes, Jaguar

The all-aluminium quad-cam engine 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).

The high-pressure die-cast lightweight aluminium block is stiffened with cast iron liners and cross-bolted main bearing caps, providing refinement to match its power. The four-valve cylinder heads are constructed from recycled aluminium, between them sitting the Roots-type twin vortex supercharger fed by two intercoolers. These feature their own water-cooling circuit to reduce the temperature of the pressurised air to optimise power and efficiency.

In order to help liberate the additional 40PS and 55Nm of torque over the standard XFR, larger front air intakes in the lower bumper of the Jaguar XFR-S allow greater volumes of air to be fed into the engine. The intake system also features a symposer that channels more of the induction noise into the cabin, adding to the aural excitement of driving the Jaguar XFR-S.

The result is a 0-60mph time of 4.4 seconds (0-100km/h in 4.6 seconds) and an electronically-limited top speed of 186mph (300km/h).

The exhaust system has been optimised in order to channel the waste gases away from the engine with the greatest efficiency. The central silencer has been replaced with an X-piece and near straight-through rear pipes combining to provide an enhanced exhaust note with the added benefit of a motorsport-style crackle on the overrun.

A number of key driveline components have been uprated in order to both adapt the Jaguar XFR-S for the greater power and torque outputs and stiffen the entire drivetrain to make its responses more immediate; these include uprated driveshafts, a larger central bearing on the propshaft and a new torque convertor.

This series of changes has allowed Jaguar's engineers to tune the throttle response to suit the more focused nature of the Jaguar XFR-S. Applying learning from the new F-Type sports car, the response to throttle inputs has been made significantly quicker. The end result is an intimate connection between the driver's right foot and the engine. Engaging Dynamic Mode increases this still further with a greater engine response for a given movement of the accelerator pedal.
