E85 Chassis: Notes

The proven chassis and suspension of the E46 serves as the basis for the E85. The combination of a rigid roadster body, lightweight aluminum suspension components, optimum weight distribution and rear-wheel drive are ideal prerequisites for pure driving pleasure with the BMW E85 Z4. The development objectives of E85 Z4 were to further improve the roadster handling characteristics as compared to the predecessor while retaining the outstanding driveability for everyday use.

The front axle has been taken directly from the E46. The service brakes, pedal assembly, hydraulics and brake calipers are essentially the same as the E46. Because of the widened track, the E85 has been given new brake discs with a different depth on the rear axle.
