The NSU Pipe 25/40 PS was a car intended for upper class customers, which NSU built in the years 1908 and 1909 under the license of the Belgian automobile manufacturer Pipe. This was the first - and for a long time only - six-cylinder model of the brand and the only car ever built by NSU for the upper class.[1]
The water-cooled engine was a six-cylinder motor with a displacement of 6494 cm³ (bore × stroke = 105 × 125 mm), which produced 40 PS (29 kW) at 1100 rpm. The engine had magneto ignition, automatic central lubrication and overhead valves.[1] The power was transmitted to the rear wheels via a leather cone clutch, a three-speed gearbox with a right-hand shift mechanism and a chain. The wheelbase of the car was 3280 mm, the track was 1457 mm and the weight of the chassis was 1100 kg. The top speed was about 100 km / h.[1]
The cars were only produced as a double phaeton. In 1909, its production was discontinued without a successor.[1]
