Dynamic gearbox mounts

Fuel consumption* Cayman: Urban in l/100 km (mpg) 12.7 (22.2)-10.9 (25.9); Extra urban in l/100 km (mpg) 7.1 (39.8)-6.2 (45.6); Combined in l/100 km (mpg) 9.0 (31.4)-7.9 (35.8); CO2 emissions in g/km 211-183.

Dynamic gearbox mounts are a component of the optionally available Sport Chrono Package. This electronically controlled system minimises the oscillations and vibrations of the entire drivetrain, especially the engine, and combines the benefits that otherwise distinguish hard and soft gearbox mounting arrangements.

A hard gearbox mounting delivers optimum dynamic performance because it offers a high degree of handling precision. Soft gearbox 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.

Dynamic gearbox mounts adapt their stiffness and damping characteristics 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 field. For the driver, the results are tangible. Handling is perceptibly more stable under load change conditions and in fast corners. Whenever a less assertive driving style is adopted, the dynamic gearbox mounts automatically soften to enhance comfort.

The result is uncompromisingly sporty performance in corners – as well as a high degree of comfort. The SPORT or SPORT PLUS button enables you to switch the dynamic gearbox mounts from ‘Normal’ to ‘Sport’ or ‘Performance’ mode. In conjunction with optional PCM, the TFT screen in the right-hand circular instrument enables you to view the lateral and longitudinal forces as they act on the vehicle.
