Okay, we'll admit "most powerful, high performance Jeep ever made" isn't the most impressive title in the world, but it belongs to the 2012 Jeep Grand Cherokee SRT8 ($TBA) nonetheless. Powered by a 6.4-liter HEMI V-8 pumping out 465 hp — you might remember it from the 2012 Chrysler 300 SRT8 — the SRT8 Jeep goes from 0-60 in just 4.8 seconds, with a governed top speed of 155, and a slew of other features like a new adaptive damping suspension, a new active valve exhaust system, an AutoStick transmission with steering wheel paddle and console shifting options, five-spoke, 20-inch forged aluminum wheels, a one-piece front fascia for a sportier look, a dual-sport exhaust system, and all the interior appointments of a high-end SUV.
