Dynamic engine mounts

The electronically controlled system minimises the oscillations and vibrations of the entire drivetrain, especially the engine, and combines the benefits of a hard or soft engine mounting arrangement.

A hard engine mounting delivers optimum dynamic performance because it offers the highest degree of handling precision possible. Soft engine mounts, on the other hand, minimise oscillations and vibrations. While comfort is improved on uneven road surfaces, this comes at the expense of dynamic performance.

Our engineers have solved this problem by enabling the engine mounts to adapt their stiffness and damping performance to changes in driving style and road surface conditions. This has been achieved by use of a fluid with magnetic properties in interaction with an electrically generated magnetic field.

Handling is perceptibly more stable under load change conditions and in fast corners. The dynamic engine mount system also reduces the vertical oscillations of the engine when accelerating under full load. The results are greater and more uniform drive force at the rear axle, increased traction and better acceleration. Whenever a less assertive driving style is adopted, the dynamic engine mounts automatically soften to provide a greater level of comfort.
