Benz Motorwagen

The Benz Patent-Motorwagen Nummer 1 was the first car with an internal combustion engine. After Karl Benz had filed the respective patent No. 37435 in January 1886, the first road tests were carried out in July of the same year. The four stroke engine with one cylinder had a displacement of 0,95 litres. It already showed several features of modern engines, e.g. an electric ignition, a camshaft with balance weights as well as water-cooling which worked via evaporation. At 400 rpm, the output of the engine was 0,9 HP, the top speed was 16 km/h. Benz abandoned a gear change, but the torque was distributed to the rear wheels via a differential gear. The first longer journey was made by Benz’ wife Bertha without her husband’s knowledge. Together with her sons, she drove the 106 km from Mannheim to Pforzheim. This was widely recognized and contributed significantly to the latter commercial success of the car. Karl Benz was a German engineer and pioneer of the automobile. In addition to the famous motor car, he developed a two stroke internal combustion engine, the differential gear and other automobile components like the Ackermann steering, spark plugs, the clutch, the carburettor, the radiator and the gear shift. In 1926, his company Benz & Co. Rheinische Gasmotorenfabrik Mannheim merged with the Daimler Motorengesellschaft to become Daimler-Benz AG.
