Reliability where you need it most.

Brake system and Tyre Pressure Indicator.

The high-performance brake system in the BMW 3 Series Convertible provides you with unlimited driving comfort whatever the situation. The intelligent system delivers both unequalled performance and responsiveness. The Tyre Pressure Indicator (TPI) constantly monitors air pressure to deliver outstanding safety. As soon as tyre pressure drops 30% below its normal value, the Check Control Display in the cockpit instantly informs the driver.
