Within the framework of the project AWD2020, which is funded by the Federal Ministry of Economics and Energy and the TÜV Rheinland, a cost-effective and highly efficient all-wheel-drive system for the growing volume segment of the B-SUVs will be developed in cooperation with GKN Driveline. By an expansion of a conventional all-wheel drive system with innovative shut-off elements and a low-cost 48V auxiliary drive a significant CO2 reduction of 15% compared to state of the art systems will be achieved. Using simulations various four-wheel topologies and hybridization options are investigated and evaluated with regard to their CO2 savings potential. Furthermore Hybrid strategies based on the 48V auxiliary drive are developed and evaluated. The additional drive machine will be designed by the IEM.
