SPS automotive performance just bought th elast available Benz-Patent-Motorwagen for a privat collection. This is one of 150 cars which have been reproduced by Mercedes Benz Classic, following exactly the original from 1885. With the original vehicle Berta Benz and her sons drove from Mannheim to Pforzheim – that was on the 5th of August 1888.
This replica from Mercedes Benz Classic is made 1:1 like the original vehicle.
The first Motorwagen used the Benz 954 cc single-cylinder four-stroke engine. This new engine produced ⅔ hp (½ kW) at 250 rpm in the Patent-Motorwagen, although later tests by the University of Mannheim showed it to be capable of .9 hp (0.7 kW) 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 carburetor, rather a basin of fuel soaked fibers that supplied fuel to the cylinder by evaporation.
