Introduction
The reliable and as yet unsurpassed double joint spring strut axle with tension struts (based on the basic E39) is used as the front axle in the new E65. The reworked and fine-tuned integral axle is once again used at the rear. The weight of the unsprung masses has been reduced by approx. 30%. The parking brake, also known as the electromechanical parking brake (EMF), is also new. It is an automated, convenienceoriented system which functions via the DSC hydraulics and an electromechanical control unit, which in turn acts on a DuoServo drum brake. The E65 is steered by rack and pinion power steering with a variable transmission ratio. The standard E65 rim is a lightweight forged wheel fitted with a trim.
