The 2005 BMW M3 is a high-performance version of the 3-series, with its roots firmly planted in BMW's motorsport legacy. Belonging to the fourth generation, the M3 is available as a coupe or a convertible. It is powered by a gutsy 3.2L inline-six engine that churns out 333 hp and 262 lb-ft of torque, mated to either a standard 6-speed manual or an optional Sequential Manual Gearbox (SMG) that boasts of F1-style paddle shifters. Rear-wheel drive is the only drivetrain. Inside, the M3 is replete with luxury appointments and modern conveniences. All models come with stability control, four-wheel antilock disc brakes, and side airbags as standard. The M3's in-car entertainment composes of a standard Harman Kardon audio system. Key model-year changes include LED tail lights and turn signals and the addition of a special Competition Package, with enhanced steering and braking capabilities, exclusive 19-inch wheels, and a track mode setting for the stability control.
