The Mercedes 630 .Manufactured by Daimler-Benz AG, Stuttgart-Untertütkheim. Germany The first contacts between Daimler Motoren Gesellschaft atUntertürkheim and Benz & Co, Rheinische Automobil und Motorenfabrik, Mannheim were started in 1919, but it was not until June 29, 1926, that the Daimler three-pointed star was combined with the circular laurel wreath of Benz, and a new company, Daimler-Benz AG, was established.
Two years before this amalgamation the 630 Mercedes model, forerunner of the famous supercharged cars was announced. It was also designated as 24/100/140, in which 24 indicated the taxable horsepower, 100 the output without supercharger, and 140 the output with supercharger. It was built by Ferdinand Porsche, who started working for Daimler in 1923. The supercharger was developed by Daimler's son Paul, when working as the chief designer atUntertürkheim, but after the failure of his 2 litre sports car in Indianapolis Paul gave up designing.
The car was bought by wealthy industrialists and entertainers. Soon this six-cylinder monster tourer was followed by the 4 litre Model 400' designated as 15/70/100. This open version was owned by President Paul von Hindenburg of Germany.
Later on several sports cars were derived from the 630 model, such as S, S.S. and SS.K., which in the late 1920s and early 1930s scored many successes in racing.
Engine: The 630 model was powered by a 6240 cc in-line six-cylinder engine, with bore and stroke of 94 x 150mm and compression ratio of 4.7:1. The engine developed a maximum of 73.5kW (100hp), or 103kW(140hp) with Root compressor, at 3000 rpm. The cylinder block,crankcase, and pistons were fabricated from light alloy, the cylinder liners and the valve head from cast steel.
Transmission: The drive was transmitted to the rigid rear axle through a multiple disc clutch and a four-speed gearbox.
Chassis Body: The chassis was fitted with mechanical brakes with vacuum boosters on all wheels. This 2500kg (55001b) seven-seater limousine with its 3.75m (12ft 4in) wheelbase, looked very impressive.
