The 2012 BMW 3 Series is available in sedan, coupe, hardtop convertible and wagon body styles. Every body style starts off in 328i guise. The sedan comes standard with 17-inch alloy wheels, adjustable drive settings, automatic headlights, foglights, automatic wipers, cruise control, automatic dual-zone climate control, a tilt-and-telescoping steering wheel, eight-way manual front seats, leatherette premium vinyl upholstery, a leather-wrapped steering wheel, Bluetooth phone connectivity, the iDrive electronics interface and a premium sound system with a CD player, HD radio, an auxiliary audio jack and an iPod/USB audio interface. The coupe differs with a sport-tuned suspension, while the convertible gets a fully powered retractable hardtop and 10-way power front seats with memory functions. Both two-door body styles add adaptive xenon headlights and a 60/40-split-folding rear seat. The 335i primarily represents a more powerful engine and is available on all but the wagon. On the sedan, it also adds 18-inch alloy wheels, adaptive xenon headlights, automatic high beams, a sunroof, eight-way power front seats (with four-way power lumbar) and an auto-dimming mirror. The coupe and convertible are similarly equipped, but lack the auto-dimming mirror and automatic high beams. The convertible adds heat-reflective leather upholstery. Every 2012 BMW 3 Series comes standard with antilock brakes, traction and stability control, front side airbags and side curtain airbags.
