MERCEDES-BENZ SS.Manufactured by Daimler-Benz AG, Stuttgart-Untertürkheim, Germany After Gottlieb Daimler's son Paul retired from his post of chief designer at Untertürkheim, where he had been since 1907, Ferdinand Porsche was the new name in the Mercedes design department. Porsche designed 2 litre eight-cylinder engines developing 95.53kW (130hp), or 110.2kW (150hp) with supercharger, which were used in the racing cars. At the same time he produced six-cylinder engines designed for production cars.
These cars were the 400 fitted with a 4 litre engine and developing 51.48kW (70hp) or 73.47kW (IOOhp) with a supercharger, and the 630 with a 6.3 litre engine developing 73.47kW (100hp) or 102.26kW (140hp) respectively.
In 1926 Daimler and Benz merged as Daimler-Benz AG. In 1927 the new firm responded to the modern designing trends by announcing 2500kg (55001b) cars with large wheels, and a new type, 630 K. 'K' stood for short wheelbase (Kurz). The 630 K was followed by the 680 S, on which successful racing cars were based owing to the car's light chassis.
The engine's capacity was steadily increased and the chassis weight dropped from 1500 to 1270kg (3300-28001b). Then the 710 SS with a 7065 cc engine was announced. With a bore and stroke of 100x150mm it could develop 124kW (170hp) at 2900 rpm, or 150.61kW (225hp) at 3300 rpm in the supercharged version. The engine was of an advanced design: the engine block, the cranckcase, the cylinder heads, and pistons were made of light alloys. The liners and the cylinder head were cast steel, the crankshaft was of chrome- nickel steel. The engine was sealed with a gasket only, placed under the cylinder head.
This car scored its first win in the 1927 Nürburgring race, where Mercedes were placed first, second, third and fifth. In 1928 Ferdinand Porsche left the company. His successor Hans Nibel, also an outstanding engineer, strongly influenced further development of the factory.
From 1929 onwards the short version, designated SSK, was mostly built for racing, and the SS was fitted with passenger bodies. Over the years 1928-1934 a total of 300 of the S, SS, SSK, and SSKL models were built,
