The Grand Cherokee is legendary for its rugged off-road capability, sensible size and car-like ride and interior. While most SUVs have grown to near-gargantuan proportions, the 2009 Jeep Grand Cherokee remains true to the general size of the original 1992 model. Engine choices, however, have grown larger and include a fuel-efficient V6, a 4.7-liter V8, a powerful HEMI V8 and, for a limited time, a torque-happy turbodiesel. Jeep also offers a choice of three four-wheel-drive systems, which range from a basic shift-on-the-fly high/low transfer case to a permanently engaged system capable of sending power to whichever wheel has traction.
