The Jeep Liberty offers a good compromise between road-worthiness and off-highway capability for a compact SUV. The Liberty, offered in two-wheel drive or four-wheel drive, is available in three trim levels, Sport, Limited, and the new-for-2012 Jet Edition. The standard powertrain in all Liberty models is a 210 horsepower 3.7-liter V6 and a four-speed automatic transmission. Standard equipment includes SIRIUS satellite radio, electronic stability control, anti-lock brakes with brake assist, all-speed traction control, and electronic roll mitigation. The Jet Edition trim features 20-inch polished wheels, chrome body side moldings, blacked-out headlamps and unique 'Jet' badging. 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. A multimedia infotainment system with 30-gigabyte hard drive and navigation system is available. For 2012, the Renegade trim has been discontinued and the Jet Edition package (first offered in the 2011 model year) is now a trim.
