All-new 2012 Jeep Grand Cherokee SRT8
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.
