The experimental EX120 has an engine bore reduced to 54mm and a stroke reduced to 81mm, to give a capacity under the 750cc limit. The car is finished with a very simple lightweight body and a small supercharger is fitted to the engine. The car was taken to Montlhéry, just outside Paris in January 1931 where speeds in excess of 100 mph were achieved, the first time for a car of under 750cc. There was further success for the car later in the year when it completed over 100 miles in the hour, another first for this capacity.

The MG Car Company, introduced the production version of EX120 – the C type, which is also known as the ‘Montlhéry Midget’. The bore is reverted to a 57mm and the stroke reduced to 73mm, still keeping the capacity under 750cc. Transmission is through a four-speed manual ENV gearbox. With the supercharged engine the top speed is about 100 mph. C type bodies retains the open two-seat configuration of the M type complete with an opening rear boot which now contains the rear mounted petrol tank. The body is doorless and features two large ‘humps’ on the scuttle, designed to deflect air over the driver and passenger. Just like the “12/12” M type the year before, the C types first racing success was in May 1931 at the JCC Double Twelve race at Brooklands where it won the race outright and the three car, Team Award.

The D type MG was introduced at the London Motor Show in October 1931. It represents a four-seat version of the M type, built on a slightly longer version of the C type chassis. The engine, transmission and brakes are taken straight out of the M but the car is equipped with a very attractive open four-seat body with front-hinged, slightly cut-away doors and the electrics are upgraded to 12 volt.

The F Magna has extended version of the C type chassis to accommodate the longer 6 cylinder engine derived from the Wolseley Hornet. The body styles follow the D type pattern with an open, four-seat, and closed four-seat salonette.
