Mercedes 10/40/65 HP
You can see it not directly this car, but it introduces a whole series of innovations. There the compressor is, by now well to recognize on the sideways of the engine compartment emerging exhaust pipes. Here there are two for one four-cylinder. The type designation is made more complicated because the engine is indicated in its performance with and without charge. Before that are still listed the tax-PS, which count 261.8 per cm³, in this case that is 10.
The compressor can be controlled via the accelerator pedal. When operating (for max. 1 minute) a multidisc clutch engages and the compressor significantly increases performance and rotation speed. Paul Daimler, son of company founder and Max Sailer pursue this idea from the aircraft engines since the war ended in 1918. But only now the engines are stable enough. Almost more important than the compressor is the new engine management with two overhead camshafts and drive train through offset bevel drive shaft. Add the still in this model realized mechanical four-wheel brake.
