Highly efficient at low engine revolutions, electric superchargers make it possible to downsize engines. When coupled with an energy recovery system, electric superchargers can be used to create a cost-competitive hybrid solution that can deliver fuel savings of up to 20% in the standard European driving cycle, Valeo said.

The advantage is significantly accelerated pressure build-up, which leads to very responsive downsized engines. Various other design modifications optimize fuel economy and comfort as well: Low-friction bearings and two-stage oil pump reduce friction. This, in turn, improves the fuel economy of all MQB-based models.
