For the first time Karl Benz publicly drove the car on July 3, 1886, in Mannheim at a top speed of 16 km/h (10 mph). ![]() Benz unveiled his invention to the public on 3 July 1886, on the Ringstrasse in Mannheim. 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. The vehicle was awarded the German patent number 37435, for which Karl Benz applied on 29 January 1886. 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. An evaporative carburettor was controlled by a sleeve valve to regulate power and engine speed. A large horizontal flywheel stabilized the single-cylinder engine's power output. 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. It was an extremely light engine for the time, weighing about 100 kg (220 lb). 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. The first Motorwagen used the Benz 954 cc (58.2 cu in) single-cylinder four-stroke engine with trembler coil ignition. A simple belt system served as a single-speed transmission, varying torque between an open disc and drive disc. Fully elliptic springs were used at the back along with a beam axle and chain drive on both sides. Steering was by way of a toothed rack that pivoted the unsprung front wheel. The steel-spoked wheels and solid rubber tires were Benz's own design. It was constructed of steel tubing with woodwork panels. ![]() ![]() The vehicle contained many new inventions. The Benz Patent-Motorwagen was a motor tricycle with a rear-mounted engine. 3 of 1888, used by Bertha Benz for the first long-distance journey by automobile (106 km (66 mi) long)Īfter developing a successful gasoline-powered two-stroke piston engine in 1873, Benz focused on developing a motorized vehicle while maintaining a career as a designer and manufacturer of stationary engines and their associated parts. 1 used in Karl Benz's first trip on 3 July 1886 The Benz Patent-Motorwagen Nr. Development, specifications and Karl Benz's first drive Benz Patent-Motorwagen Nr. ĭue to the creation of the Patent-Motorwagen, Karl Benz has been hailed as the father and inventor of the automobile. Two years after Karl Benz first drove the car in July 1886, 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. The original cost of the vehicle in 1886 was 600 imperial German marks, approximately 150 US dollars (equivalent to $4,900 in 2022). The Benz Patent-Motorwagen ("patent motorcar"), built in 1885 by the German Karl Benz, is widely regarded as the first practical modern automobile and was the first car put into production. 1.0L (954cc) single cylinder engine 2⁄ 3hp ( Ligroin)
