1886 Benz Patent-Motorwagen
- Brand: Benz
- Car Code: 111181
The Benz Patent-Motorwagen ("patent motorcar"), built in 1885 by the German Carl Benz, is widely regarded as the world's first practical modern automobile and was the first car put into series production. It was patented and unveiled in 1886. The original cost of the vehicle in 1886 was 600 imperial German marks, approximately 150 US dollars (equivalent to $4,500 in 2021).
Karl's wife Bertha demonstrated its feasibility in a trip from Mannheim to Pforzheim in August 1888, shortly before it became the first commercially available automobile in history in the late summer of 1888.
Due to the creation of the Patent-Motorwagen, Benz has been hailed as the father and inventor of the automobile.
The first Motorwagen used the Benz 954 cc (58.2 cu in) single-cylinder four-stroke engine with trembler coil ignition. This new engine produced 500 watts (2⁄3 hp) at 250 rpm in the Patent-Motorwagen, although later tests by the University of Mannheim showed it to be capable of 670 W (0.9 hp) at 400 rpm. It was an extremely light engine for the time, weighing about 100 kg (220 lb). Although its open crankcase and drip oiling system would be alien to a modern mechanic, its use of a pushrod-operated poppet valve for exhaust would be quite familiar. A large horizontal flywheel stabilized the single-cylinder engine's power output. An evaporative carburettor was controlled by a sleeve valve to regulate power and engine speed. The first model of the Motorwagen had not been built with a carburettor, rather a basin of fuel soaked fibers that supplied fuel to the cylinder by evaporation.
The vehicle was awarded the German patent number 37435, for which Karl Benz applied on 29 January 1886. Following official procedures, the date of the application became the patent date for the invention once the patent was granted, which occurred in November of that year. Benz unveiled his invention to the public on 3 July 1886, on the Ringstrasse in Mannheim.
