All-new 2012 Jeep® Grand Cherokee SRT8®: The Ultimate Performance SUV

The most powerful, technologically advanced, high-performance Jeep® vehicle ever – the all-new 2012 Jeep Grand Cherokee SRT8® – arrives this summer with a combination of Jeep’s legendary capability and utility, merged with the renowned advanced performance engineering from Chrysler Group LLC’s Street and Racing Technology (SRT®) team.


Powering the 2012 Jeep Grand Cherokee SRT8 is Chrysler Group’s all-new 6.4-liter HEMI® V-8 with 
Fuel Saver Technology that delivers an estimated 465 horsepower and 465 lb.-ft. of torque – an improvement of 45 horsepower and 45 lb.-ft. torque over the 6.1-liter HEMI V-8 it replaces.


An active intake manifold and high-lift camshaft with cam phasing delivers maximum low-end torque while optimizing high-end power across a wider and improved rpm band. Specifically, 90-percent of peak torque is available between 2,800 and 6,000 rpm, allowing for inspired standing starts and improved straight-line performance. 


Standard Fuel Saver Technology and a new-for-2012 active valve exhaust system allows four-cylinder operation to engage over a wider rpm range, to deliver both improved fuel efficiency – an estimated 13-percent increase on the highway – and an extended range of approximately 450 miles on one tank of gas.

Designed and built using the proven SRT formula that raises the performance to astonishing levels, the new 2012 Jeep Grand Cherokee SRT8 runs from 0-60 mph in 4.8 seconds, 0-100-0 mph in the mid-16 second range, can cover the quarter mile in the mid-13 second range, has a top speed of 155 mph, and brakes from 60-0 mph in 116 feet. And, it has a trailer tow rating of 5,000 lbs.


All-new Chrysler 300 SRT8 with its 6.4-liter HEMI V-8 is Chrysler’s most powerful, best-handling sedan ever

The new 2012 Chrysler 300 SRT8 adds high-performance hardware to the elegant proportions and head turning design of the 2011 Chrysler 300C to provide the ultimate combination of world-class luxury, power and handling. With an estimated 465 horsepower and 465 lb.-ft. of torque, the 300 SRT8 is targeted at customers that seek heart pounding, adrenaline filled excitement, but don’t want to sacrifice comfort and innovative features to get it.


Under the hood of the 2012 Chrysler 300 SRT8, the new 6.4-liter HEMI V-8 makes its debut in the Chrysler brand product lineup delivering an estimated 465 horsepower and 465 lb.-ft. of torque, up 40 horsepower and 45 lb.-ft. over the 6.1-liter HEMI V-8 it replaces.

Projected performance numbers include 0-60 mph acceleration in the high 4-second range; quarter mile in high 12 second range; 0-100-0 mph in less than 16 seconds, top speed of 175 mph and stopping power from 60-0 mph in 120 feet. 


Even with the elevated power numbers, an estimated 25-percent fuel economy increase on the highway is achieved by use of a new-for-2012 active valve exhaust system that allows the standard Fuel Saver Technology (four-cylinder mode) to engage over a wider rpm range. The new active exhaust system also allows for straight-through mid and rear mufflers for a throaty exhaust note under engine load.
