ProActive Rear Drive Module, MagnaUS – The company’s Powertrain operating unit is providing an all-wheel-drive (AWD) system for the new compact SUV, as well as the A45 AMG and the CLA. The product was jointly developed by Magna and Daimler, with the former focusing on the rear axle drive and AWD coupling, and the latter handling the integration.

The ProActive Rear Drive Module has been specifically designed as a platform solution for C-segment vehicles, with a high level of integration for an AWD coupling and rear axle drive. According to Magna, the system significantly improves vehicle performance in terms of drag, torque, system efficiency and weight.

The high level of integration has been achieved through the use of a common oil circuit to improve the coupling function in extreme conditions and to downsize the packaging. Magna says the elimination of seal rings and bearings reduces drag by around 14%, resulting in lower CO2 emissions, and decreases mass by 2kg, giving a 10% improvement and setting “a new benchmark” for AWD systems.
