The front-wheel drive Caliber is available in five "lifestyle" trims: Express, Mainstreet, Heat, Rush and Uptown. All trim levels, with the exception of the Rush, are outfitted with a 158-hp 2.0-liter 4-cylinder engine, while the Rush gets more power in the form of a 172-hp 2.4-liter 4-cylinder engine; available transmissions include a five-speed manual and a Continuously Variable Transmission (CVT). Every Caliber is equipped with air conditioning, cruise control, a CD player with MP3 capability, satellite radio, iPod control and UConnect wireless connectivity. Additional trim-dependent features include 17- and 18-inch alloy wheels, a power sunroof, fog lamps, heated front seats and leather upholstery, along with a multimedia centre boasting a hard drive-based navigation system with 30 gigabytes of internal memory, a touch-screen LCD display and DVD video capability. Safety features include anti-lock brakes, active anti-whiplash front head restraints, front airbags, an inflatable driver knee blocker, and side curtain airbags for front and rear occupants; an electronic stability control system, including traction control and brake assist, is standard on all but the Express. The Dodge Caliber carries over with minimal changes for 2011. Electronic stability control, including traction control and brake assist, is now standard on all but Express trim levels, while the Mainstreet gets a 6-way power driver's seat. Additionally, the optional navigation system gains real-time traffic information.
