Front Axle

2011 BMW Alpina B7LSECTION 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:

  • Higher transverse acceleration is reflected in greater vehicle agility.
  • Improved cornering/steering and transition characteristics which are particularly favorable in terms of rolling motion.
  • Reduced interference means greater comfort.
  • Shock absorbers that are subjected to virtually no transverse forces provide greater comfort.
  • The design layout of the double wishbone front axle facilitates vertical dynamics control (VDC) and all-wheel drive (as on the E70/E71) without the need to adjust height and no spring travel loss.
  • Double wishbone front axles improve directional stability.

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.
