The 2008 Jeep Liberty is redesigned for the first time since its 2002 model-year introduction. Liberty shares its basic design with the Dodge Nitro. Available in two models, the Sport and the Limited, the Liberty uses a 210-horsepower 3.7-liter V6 with a 6-speed manual or automatic transmission. Maximum towing capacity is 5000 lb. Rear-wheel drive is standard, and two 4WD systems are available: The Selec-Trac II can be left engaged on dry pavement, the Command-Trac should not be left engaged on dry pavement. Both include low-range gearing for off-road use. The 2008 Jeep Liberty marks the debut of the Sky Slider, a retractable canvas roof that opens over both seating rows. Available safety features include ABS, traction control, an antiskid system, and curtain side airbags. Also available are a navigation system and satellite radio. The 2008 Jeep Liberty is larger than its predecessor in every dimension, with more cargo capacity and passenger space.
