Jeep has introduced a comprehensive update for the Grand Cherokee SRT8.

Aside from revising the regular Grand Cherokee versions, Jeep has prepared an update for the high-performance SRT8 variant that has received a different front grille, LED headlamps and a restyled rear spoiler, along with a new set of five-spoke alloy wheels.

In terms of performance, the 2014 Grand Cherokee SRT8 features a new launch control feature and a tweaked Selec-Track system which is now sending more torque to the rear wheels for improved performance whilst Track Mode is turned on. The most significant change is the addition of an 8-speed, quick-shifting automatic transmission which should lower fuel consumption and enhance performance.

The 6.4-liter HEMI V8 engine has the same 470 hp (350 kW) and 465 lb-ft (630 Nm), but the SUV should be quicker in the 0-62 mph (0-100 km/h) with the new gearbox. The previous version did it in five seconds, on its way to a top speed of 160 mph (257 km/h).
