The MG R-type is a motor car that was produced by MG in 1935. It was designed for competition use and was a development of the Q-type. The car used a tuned short-stroke (73 mm) version of the bevel-gear driven overhead camshaft engine from the 1928 Morris Minor and Wolseley 10. This had already been highly tuned for use in the Q-type and was further modified, especially in the input area, to improve reliability. It was fitted with a Zoller supercharger and produced 110 bhp (82 kW) at 7200 rpm. The gearbox was a four-speed preselector type unit. At the rear the differential in its aluminium casing was fastened to the chassis and drove the wheels through short shafts with sliding splines and universal joints.
