The earlier variant of the 8/20 PS was sold from 1912 to 1918, and was fitted with a 1950cc four-cylinder inline engine capable of generating 20 bhp (14.7 kW) of output at 1800 min-1. Engine power was transmitted via a leather cone clutch to a four-speed gearbox, and from there via a propshaft to the rear wheels. The vehicle had a top speed of 62 km/h and consumed 14 to 15 l of petrol per 100 km. It weighed between 1000 and 1200 kg, measured 4000 mm long, 1600 mm wide, and 2050 mm wide, and rode on a wheelbase of 2850 mm. This earlier variant was sold as a bare chassis with wooden spoke wheels and tires for 6500 goldmark, as a two-seater for 8250 mark, as a roadster for 9150 mark, and as a saloon for 10,200 goldmark.
The second variant, which was built from 1914 to 1921, was identical in appearance to its slightly earlier counterpart and was offered with the same body styles. However, the displacement was increased to 2090cc and the engine generated an output of 20 bhp (14.7 kW) at 1900 min-1, allowing the vehicle to reach speeds up to 65 km/h.
