The 2013 Jeep Grand Cherokee reimagines the SUV-crossover genre with an all-new design and an incredibly sophisticated interior that blurs the line between luxury and rugged off-roading. It also improves transmissions and ride quality, making it one of the most civilized SUVs ever built. Designed during the brief marriage of Mercedes-Benz to Chrysler, the new Grand Cherokee borrows some parts from the M-Class platform; this has allowed the new model to achieve a remarkable level of stiffness that's not found in most other vehicles in its class. It's a feat that's accentuated by a massively longer wheelbase, which makes the rear seat much more accessible and allows for the use of soft materials in an effort to make the cabin feel more like a limousine. There's a 5.7-liter Hemi engine, which produces 360 hp and 390 lb.-ft of torque to the rear wheels through a six-speed automatic. That's enough to give the Grand Cherokee a healthy dose of performance, and it'll help it get up to speed quickly in urban traffic. For off-roaders, the Quadra-Lift air suspension provides adjustable ride height that's easy to adjust, and it offers several traction-control settings. The system can also be programmed to let the driver select a specific mode for various terrains, such as automatic, sport, snow, mud or rock.
