On April 20, 2011, Jeep announced that the SRT8 version would be debuted at the 2011 New York Auto Show. According to Chrysler, it is the most powerful Jeep ever built. 0–60 and quarter-mile times time in at 4.7s, 13.4 seconds respectively.[30] Auto reviews measured this at 4.5 seconds, making the 2014 SRT the fastest Jeep ever produced.[31] The 2013-14 SRT Jeep Grand Cherokee includes a 6.4l Hemi motor, producing 475 hp/465 lb-ft tq, the strongest motor ever included in a Jeep, and one of the strongest naturally aspirated motors produced by Chrysler.
The Grand Cherokee SRT8 debuted alongside two other vehicles manufactured by Chrysler Corporation: the Chrysler 300 SRT8 and Dodge Charger SRT8, both of which also took a one-year hiatus while the new models debuted.
The new Grand Cherokee SRT8, which started production on July 16, 2011, is equipped with a 470 hp (350 kW; 480 PS) 6.4 L Hemi V8 engine. Jeep claims the new SRT8 gets 13 percent better fuel economy than its predecessor. To keep the gas mileage respectable,[clarification needed] Jeep has employed a new active exhaust system that lets Chrysler's cylinder-deactivating Fuel Saver Technology operate over a wider rpm band. Chrysler claims that with the larger gas tank, the SUV can now travel up to 500 miles (800 km) on a single tank, while other sources estimate range to be 450 miles (720 km).
For 2014, "SRT8" was no longer a model of Jeep, but a separate corporate entity. The "8" was also dropped in the "SRT" line for this year, the grand Cherokee being refereed to as a "SRT Jeep Grand Cherokee." The SRT model received many new and unique features. For example, in the interior, it received a unique steering wheel with the SRT insignia, twenty-inch alloy wheels, performance tires, and additional SRT-only details including:
SRT-only 6.4l, 475 hp/465 lb-ft tq, the strongest motor offered in a Grand Cherokee ever, propelling it to 0-60 in 4.5 seconds, making it the fastest jeep ever produced
four-piston brembo brakes
3 season tires (optional)
SRT-only performance pages in the head unit, displaying engine statistics, quarter mile/0-60, and other metrics
Napa leather seats with SRT-only alcantara inserts and headliner
SRT-only facia covering hitch (if so provisioned)
SRT-only suspension modes, including track mode
SRT-only "launch" mode, designed to modeled world class professional driver techniques
upgraded software for transmission, with over 90 gear shift programs
The new Grand Cherokee started production in late January 2013, and as a 2014 model year.
2015
The 2015 Limited Edition model no longer has the dual exhausts. This feature only comes in the Overland and up editions. There are no other major changes for the 2015 model year. However, the Limited, Summit, and Overland trims will include HD Radio as part of the U Connect feature. The SRT receives a modest 5 hp bump, in part due to a reflash of the PCM.
