2012 Jeep Grand Cherokee

Jeep released an all-new Grand Cherokee for 2011 and significantly upgraded every aspect of the vehicle. The flagship Jeep retains the uncompromising off-road capability of its predecessors thanks largely to a trio of available four-wheel-drive systems and an optional air suspension that offers five height settings. Selec-Terrain electronically calibrates the vehicle to handle different conditions via a five-position dial. The Grand Cherokee will spend most of its time on dry, paved roads, though, where it behaves like a typical luxury SUV. The base engine is Chrysler's 3.6-liter Pentastar V-6, which offers a respectable 290 hp. The optional 5.7-liter V-8 makes 360 hp and is paired with a six-speed automatic transmission. Horsepower fans will likely opt for the new SRT8 model and its 470-hp, 6.4-liter Hemi V-8 engine. Surprisingly -- at least to those familiar with past Grand Cherokees -- interior quality and execution are the biggest strengths of the new version, with standard features such as keyless ignition and satellite radio and optional features that include a heated steering wheel, a panoramic sunroof, and a navigation system. Jeep has covered all the mid-size-SUV bases with an efficient V-6; an optional 5.7-liter V-8 that can tow up to 7400 pounds; and now a track-tuned SRT8 model that can blast from 0 to 60 mph in 4.6 seconds, run a thirteen-second quarter mile, and reach 160 mph.
