Although the M3 is quite complete, there is an option list, containing items like DVD navigation, the competition brakes, Electronic Damper Control, the MDrive electronic control system, adaptive headlamps that turn corners before the car does, an optional interior lighting scheme that paints a rim of light around the entire cockpit, leather upholstery, and a 16-speaker, 825-watt sound system.
An important option is MDrive, an electronic control system that enables the driver to tailor suspension, steering, and engine performance to his own personal tastes and style, with almost 300 possible combinations, using a single button on the multi-function steering wheel to switch from the normal mode to the M mode. The MDrive system was piloted on the larger, more expensive M5 sedan and M6 coupe and convertible and is available on the new 3 Series for the first time. Another new feature is the Variable M Differential Lock, which automatically apportions traction to the two rear tires depending on which has more grip at the moment, a feature that really enhances high-performance driving in bad weather conditions or on twisty roads.
