A lightweight vehicle engine mount made of plastic instead of aluminum has gone into production for several small-car models, including electric vehicles, produced by the Renault-Nissan alliance.

The part, which was developed by ZF Friedrichshafen AG, is about 25% lighter than a conventional cast metal mount but provides the same ability to isolate powertrain vibration from the vehicle body.

Like its metal counterpart, the plastic mount includes a rubber insert.

The new design uses fiberglass-reinforced polyamide and is 100% recyclable, according to ZF. The company used CAD modeling to determine the concentration and alignment of the glass fibers. It says the device's modular construction makes it easily adaptable to a wide range of engines and vehicles.
