The Liberty was redesigned for the 2008 model year to appear more rugged while maintaining the classic Jeep look. Available in two trim levels, Sport and Limited, each is offered with two-wheel drive or four-wheel drive systems. The standard engine in all Liberty models is a 210 hp 3.7-liter V6. A four-speed automatic transmission, already standard on the Limited Edition, becomes standard on the Sport trim for 2009. Standard on all models is a SIRIUS satellite radio, an electronic stability program, anti-lock brakes with brake assist, all-speed traction control, and electronic roll mitigation. The SkySlider option is a full-length open canvas sunroof that can slide accordion-style forward, backward or partially opened to any position in-between.The Jeep Liberty is carried over for 2009. The manual transmission is no longer available on the Sport, so the automatic is now standard.
