Driving Experience Control.
How would you like to drive today? Driving Experience Control, fitted as standard, makes the difference. Adapt your BMW 5 Series Sedan to meet your needs – or those of your passengers.
A touch of the Driving Experience Control next to the gearshift lever changes the level of driving pleasure from COMFORT to SPORT: the engine responds more spontaneously to the accelerator and the eight-speed transmission Steptronic lets the engine rev high before quickly changing up a gear. At the same time the steering and chassis tighten
. Touch the paddle again to enter the SPORT + mode where the Dynamic Stability Control allows controlled drifting to the limit.
The currently active mode is permanently displayed underneath the speedometer, and in the SPORT mode the drive train and chassis settings can be quickly and individually configured using the iDrive Controller for dynamic driving on badly surfaced roads for example.
The COMFORT+ mode is available with Dynamic Damping Control which provides both the driver and passengers with maximum comfort on longer journeys.
