Why it matters
The R-type was a single-seat racing MG with a boxed Y-shaped backbone chassis and all-independent torsion-bar suspension, a radical layout for 1935. Only ten were built before the parent Morris company ordered all racing work stopped, making it the last works racing MG of the era.

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
MG chief designer H. N. Charles began official work on an all-independent suspension car in 1934. The result used a boxed Y-shaped frame with the Q-type-based 746 cc engine in the fork, unequal-length front wishbones, equal-length rear wishbones and torsion bars running along the chassis. Its wheels stayed upright but the body leaned heavily in corners, which unsettled drivers. Production took place around April–May 1935, after which Morris Motors ordered an immediate end to racing-car work.
