Front Axle
A double wishbone front axle as known from the E70 and E71 is now also fitted in the F01/F02.
In comparison with the double pivot spring strut front axle on the E65, this front axle design offers the following advantages:
The outstanding driving dynamics, the excellent driving comfort as well as the exceptional directional stability are factors of this double wishbone front axle design solution that contribute to a high degree of driving pleasure and safety while making the vehicle ideal for every day use and providing the most relaxing drive on long journeys.

Rear Axle
Compared to the integral IV rear axle, the further-developed integral-V rear axle in the F01/F02 is characterized by further improved driving dynamics without compromising comfort and driving safety.
Furthermore, a "distributed" integral-V rear axle was required in order to realize HSR (rear axle slip angle control) that is a fundamental part of the integral active steering system.
Dampers/suspension
In the F01/F02, the range of spring/damper units extends from the steel spring with standard vertical dynamics control (VDC) through to the electronically controlled dampers that can also be combined with the single axle air spring on the rear axle.
Brakes
The brake system on the F01/F02 is a further developed high performance brake system with newly adapted dimensions for the F01/F02 and is dependent on the national market specification. The service brake is based on the conventional design, however, the parking brake features an electromechanical parking brake system (EMF).
Steering
The F01/F02 is available with two steering system variants:
Both steering systems are adapted to the varied application options of the F01/F02. The integral active steering is a new BMW development.
Wheels and Tires
In contrast to its predecessor the E65/E66, the F01/F02 is now equipped as standard with a runflat safety package.
