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.
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 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.
"Typically, designers have to work with features from base vehicles and integrate them into other variants. The opposite was true when it came to our rear spoiler. We created it for our SRT model and it works so well at improving aerodynamic efficiency and downforce that it was decided to incorporate it into all 2014 Grand Cherokee models," Trostle added.
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.
