Fresh off of last year's redesign, the 2012 BMW 3 Series is a compact entry-level luxury vehicle offered in sedan, coupe, convertible (hardtop), and sport wagon trim levels. All trims are available as a base 328i that utilizes a standard 2.0-liter 4-cylinder twin-turbo charged engine that produces 240 hp and 260 lb-ft of torque. Sedan, coupe, and convertible trims offer an optional 335i trim powered by a 3.0-liter twin-turbo V6 engine that produces 300 hp (convertible trim also offers a 335is trim that yields 320 hp.) An additional engine offered is an optional 3.0-liter twin turbo V6 diesel engine (335d) that produces 265 hp and 425 lb-ft of torque. Transmission options consist of a 6-speed manual, 8-speed automatic, 6-speed automatic with paddle shifters, and a 7-speed double clutch automatic. All trims, with the exception of the convertible level, offer AWD. Features include premium sound, navigation, automatic cruise control, and iPhone/iPod integration. Safety is comprised of dynamic stability control, enhanced braking, advanced airbags, and xenon adaptive headlights. The 3 series is backed by a 4-year/50,000-mile warranty.
