The NSU 2½-ton truck was a truck built by the Neckarsulmer Fahrzeugwerke Aktiengesellschaft between 1914 and 1926. It was developed from the car model 14/40 HP .
The water-cooled engine was a four-cylinder block engine with a displacement of 3380 cc (bore × stroke = 91 × 130 mm), which made 42 hp (31 kW) at 1700 / min. The engine had a triple-mounted crankshaft, magneto ignition , pressure circulation lubrication and counter-balanced valves . The fuel tank was at the back. The fuel was conveyed through the exhaust gases, with a portion of the exhaust gases was passed into the sealed tank, where it produced a slight overpressure and thus ensured that the fuel flowed forward to the carburetor. The engine power was via a multi-plate clutch in the oil bath, a four-speed gearbox with right-mounted linkage and a cardan shafttransferred to the rear wheels. The wheelbase of the cars was 3805 mm, their gauge 1500 mm and the curb weight 2200 kg. The top speed was about 35 km / h.
The fully rubber-tired car was equipped with a bunk, partly with bows and tarpaulins or even with a closed box. It was initially built only for the army , but was available from 1921 in a modified version also for private buyers. This was particularly suitable for forwarding companies that had previously operated only horse-drawn vehicles: The operating costs were according to calculations of the manufacturer at only 0.275 RM / km, while those of a horse-drawn vehicle were at 0.63 RM / km. In 1926 the construction of the 2½-tonner was discontinued wthout a successor.
