Labeled as a 2012 model, the new model will likely arrive sometime in 2011. Power is expected to come from a brand new 6.4L HEMI V8 engine rated at around the 500hp (373kW) and 500ft-lb (678Nm) of torque. Hopefully, this will be enough to allow the SRT8-prepped Jeep to cement its title as the world’s fastest SUV now that the pair of M SUVs from BMW have landed.
The new engine will be called the 392 HEMI (in reference to its capacity in cubic inches) and is expected to first appear in updated versions of the Dodge Challenger and Charger in 2011.
In addition to the power transplant, the 2012 Jeep Grand Cherokee SRT8 will also sport a subtle bodykit, a lowered ride height, stiffed suspension, and chunky SRT 5-spoke wheels housing uprated brakes.
