2012 All-New Porsche 911 (991): Dynamic Engine Mounting

You don’t have to take the new 911 onto the racetrack. But you can, more so than ever, because dynamic engine mounts are now included as part of the Sport Chrono Package. Based on the engine mounts of the 911 GT3 and 911 Turbo models, it is the first time that they have been available for the 911 Carrera. Even if track racing is not for you, dynamic engine mounts make a decisive contribution to dynamic performance on the road, too.

The electronically controlled system minimises the oscillations and vibrations of the entire drive train, especially the engine. The engine is bolted to the body by two mounts. Like any mass, it obeys the law of inertia. This means that it will continue moving in a uniformly straight line unless some force causes it to change direction. Put more simply: when you are driving into a bend, the vehicle will follow your steering but, at first, the mass of the engine will not. This means that the rear of the vehicle will ultimately be pushed outwards as a result of the engine’s force of inertia.

Dynamic engine mounts minimise this effect. Steering angle and both longitudinal and lateral acceleration are constantly recorded by sensors. The stiffness and damping performance of the engine mounts adapt to changes in driving style and road surface conditions, which is achieved by use of a fluid magnetised in an electrically generated field. This results in greater traction and perceptibly more stable handling under load change conditions and in fast corners.
