The Jeep Patriot is available in two trims, Sport and Limited, which have a standard 172-hp 2.4-liter four-cylinder engine and five-speed manual transmission; A Continuously Variable Transmission (CVT) is optional. A 158-hp 2.0L engine, available with the CVT only, is available on the FWD Sport trim. The Patriot shares its small-SUV platform with the Jeep Compass but offers off-road capability its sibling does not. It is available in front-wheel drive or with a four-wheel-drive system which utilizes a "lock" mode to enhance traction in inclement weather. The optional Freedom Drive Off-Road Group includes a continuously variable transaxle with a low range that engages when the off-road mode is activated. The package also features hill-descent control, brake lock differential, and an extra inch of ground clearance. Standard safety features include front and side-curtain air bags, anti-lock brakes, electronic stability program, and tire pressure monitoring. A power sunroof is available, and the MyGIG entertainment system with hard drive, UConnect wireless connectivity and navigation system, is a new option. For 2009, the Patriot receives a significantly upgraded interior, with improved design and quality of materials. The Sport's radio is upgraded with an MP3 player and the seats are now cloth instead of vinyl. The Limited receives a 6-CD/DVD/MP3 player with SIRIUS satellite radio.
