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.

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.

The brakes were cable-operated using 12-inch (305 mm) drums and the wheels were wire spoked and secured by a centre lock nut.

The aluminium single-seat body had the appearance of a miniature Grand Prix racer, and was designed to be easily removable.

It was realised that the suspension was giving problems, mainly with the rear being too soft, and solutions were proposed but all work stopped when new boss Leonard Lord closed the MG Racing Department.
