4.5 Dynamic engine mountings To further improve the driving dynamics as well as driving and vibration comfort, the Sport Chrono package on the new 911 Carrera models now also comes with dynamic engine mountings (Porsche Active Drivetrain Mount, PADM) as were previously only used on the 911 Turbo and 911 GT3 models.

particular from the engine to the body.
The delayed power impulse produced by the mass moment of inertia of the engine when steering into a corner or during a quick series of alternating bends, for example, is significantly reduced and any pushing from the rear minimized. Inspired by racing cars, in which the drive unit is bolted rigidly to the body, this leads to more stable and precise handling. The disadvantages are noticeable engine

vibrations and reduced day-to-day usability for a comfort-orientated driving style. This vibration is filtered by way of softer mounts.
