M836 engine
The six-cylinder in-line 3920 cc engine featured an overhead camshaft which at the time was an unusual feature, with “bevel linkage”. However, it was the switchable supercharger (”Kompressor”), adopted from the company's racing cars, that attracted most of the attention. With the device switched off maximum claimed output was of 70 PS (51 kW; 69 hp) at 3,100 rpm: with the supercharger operating, maximum output rose to 100 PS (74 kW; 99 hp).
The top speed listed was 105 km/h (65 mph) or 112 km/h (70 mph) according to which of the two offered final drive ratios was fitted.
