The P-type MG Midget was the successor of the MG J-type.
A total of 2.499 P-types have been built from 1934 until 1936.
Two models were built; first the MG PA and from 1935 the MG PB. The latter was fitted with a larger engine.

The MG Q-type was a racing car based on the MG P-type. With the Q-type MG wanted to prove that the new engine (introduced in the P-type with three crank bearings) was much stronger and much more reliable than the old Midget engine which featured only two crank bearings. The new engine gave greater smoothness and tuning potential.
MG stated that the factory warranty on the engine was even valid when a supercharger was used to tune the engine...
A total of 8 Q-type racingcars have been built. The cylinder capacity of the engine was decreased from 847 cc. to 746 cc. and a supercharger was fitted. The engine developed a minimum capacity of 110 bhp. In full race specification the engine gave away an impressive 147 bhp. at 7500 rpm.! This was the biggest performance ever achieved by a prewar engine in its days.
the Q-type used the rear axle of the MG N-type. Because the axle could not cope with the maximum power output of the engine a Wilson pre-selector gearbox was used. The gearbox was allowed to slip when overpowered and it protected the rear axle this way. The modified PB-chassis was also not strong enough to cope with this powerful engine... Today only five original MG Q-types exist.
