After World War I, Daimler-Motoren-Gesellschaft developed new passenger cars again: the 10/40 PS Mercedes and the 6/25 PS sister model. These were the world´s first standard-production passenger cars with supercharged engines. The supercharger, still called “blower” in 1923, supplied the small-displacement engine with more air, thereby temporarily boosting output from 40 PS (29 kW) to 65 PS (48 kW).
