The NSU 6/60 PS compressor was the second car that Neckarsulmer Fahrzeugwerke Aktiengesellschaft built only for racing. This vehicle was completely redeveloped and was the manufacturer's first six-cylinder model. It replaced the 5/15 HP compressor and was built in 1925 and 1926.

technology

The engine was a six-cylinder in- line engine with a displacement of 1482 cm³ (bore × stroke = 59.1 mm × 90 mm), side-mounted valves in an L-cylinder head and a Roots compressor . It developed 60 hp (44 kW) at 3800 rpm. The engine had pressure lubrication and magneto ignition with automatic ignition advance. The crankshaft had four bearings. The power was transmitted to the rear wheels via an oil bath multi-disc cone clutch, a separate four-speed gearbox with center shift and a cardan shaft . The Roots compressor was driven by the gearbox. The differential's bevel gears were spiral-toothed. The wheelbase of the car was 2850 mm, its track width 1250 mm and its weight: 830 kg. The top speed was around 175 km / h.

Races

In 1925, NSU took part in the International Taunus Race with the prototype of this car and achieved overall victory in the 450 km race. The driver was August Momberger . A year later at the German Grand Prix at the AVUS in Berlin , NSU achieved a four-fold victory in the class up to 1500 cm³. Class wins were also in several other races in 1926, e.g. B. at the Solitude in Stuttgart . This made the 6/60 hp supercharger the most successful racing car from the NSU works.

Series vehicles

From the 6/60 PS compressor, the manufacturer's first six-cylinder series vehicle was developed in 1928, the 6/30 PS .

Further whereabouts

One of the AVUS racing cars from 1926, No. 32, was later sold to a private person in Berlin, who had it fitted with a lighting system and allowed it to be used on the road in 1932. Before the Second World War , he dismantled the vehicle with the intention of restoring it. Russian soldiers found it in this condition in 1945, who actually wanted to commandeer it for their army. But they realized that they would have been unable to put it back together, and so the “parts collection” remained in Germany. At the end of December 1965, the owner sold the vehicle, which had since been restored and reassembled, to the factory and received a brand-new NSU Type 110 in return . Today the car stands alternately in the Audi Forum Neckarsulm and in the “ museum mobile ” in Ingolstadt.
