The BMW M3 is available in Coupe and Convertible models. The biggest news this year is the discontinuation of the M3 Sedan model. Major standard safety features include front seat side-impact airbags and four wheel anti-lock disc brakes. Exclusive M3 features include a 3.2L inline-six DOHC SMPI engine with 240 HP, performance tuned M suspension system, and adjustable sport seats. For vehicle security, BMWs Coded Driveaway Protection system electronically locks the engine when you remove the key from the ignition. The engine will only start with one of the special keys, embedded with a computer chip and coded for your car alone. A Harman-Kardon sound system with spatial enhancement, 320 watts, and 10 speakers is an available option.
