A convertible M3 means you get the power of a 4.0-liter V8 coupled with a power-retractable hardtop ready to offer open-air motoring with a touch. The 2012 BMW M3 Convertible comes with a 6-speed manual transmission, limited-slip differential and a performance suspension. There’s traction and stability control, upgraded 4-wheel antilock disc brakes and 18-inch alloy wheels. 10-way power adjustable front bucket seats get leather upholstery, and dual-zone automatic climate controls handle what the drop-top can’t. A leather-wrapped tilt and telescoping steering wheel has controls for the hi-definition radio, which comes with a digital-media player connection, and a memory system handles the driver’s seat and the heated power mirrors. There are heated door locks, steering-linked adaptive xenon headlights and automatic roll bars to join the dual front and front-side airbags.
The Coupe trim of the 2012 BMW M3 means the most direct application of this performance icon—the only configuration to get the carbon-fiber roof. The M3 Coupe is powered by a 4.0-liter V8, paired with a 6-speed manual transmission. A limited-slip differential is standard here, as well as a performance suspension, upgraded 4-wheel antilock disc brakes and 18-inch alloy wheels. But here you get leather upholstery with cloth insert, heated door locks, 8-way power adjustable front bucket seats, dual-zone automatic climate controls and steering-linked adaptive xenon headlights. A memory system covers the driver’s seat and the heated power mirrors, and the stereo offers hi-definition radio and a digital media player connection. For safety you get 8 airbags, including front and rear curtain airbags, and front-seat active head restraints as well as traction and stability control.
