MG Q-type

The MG Q-type was a racing car produced by the MG Car company in 1934. The chassis was based on the one used on the MG K3 but was narrower and used N-type axles. The engine used the cylinder block from the P-type but with a special crankshaft to bring the capacity down to 746 cc by reducing the stroke from 83 mm to 71 mm. A high-pressure Zoller supercharger was fitted giving a boost to 2.5 atmospheres and allowing the engine to produce 113 bhp at 7200 rpm. A sprint version was also made with output increased to 146 bhp which at nearly 200 bhp per litre was the highest specific output of any engine in the world at the time Probably only eight were made as the car was expensive at £550–£650, and the rigid-axle chassis had difficulty in dealing with the power of the engine. The single-seat version achieved a lap speed of 122 mph at Brooklands race track driven by George Harvey-Noble, and the two-seater was capable of 120 mph.
