Mercedes Grand Prix racing car of 1914 with the bonnet removed, exhaust side. The four-cylinder engine had four valves per cylinder (two intake and two exhaust valves) controlled by an overhead camshaft with vertical shaft drive. The photo clearly shows the third spark plug and the decompression tap at each cylinder. It was with this model that Daimler-Motoren-Gesellschaft achieved a triple victory in the French Grand Prix on 4 July 1914, in the sequence Christian Lautenschlager, Louis Wagner and Otto Salzer.
