Driving Resistances and the WLTP

The determination of driving resistances plays an important role during the development of a vehicle and for its certification. Since 2017, the Worldwide harmonized Light-duty Test Procedure (WLTP) has been required for the type approval of new models. Aerodynamic drag and rolling resistance are particularly important here, since both directly influence the vehicle's consumption and cannot be recovered, even in electric vehicles. FKFS has specialized test benches and simulation methods for determining air resistance and rolling resistance, and has comprehensive expertise in optimizing these driving resistances.
