The MG T-Type is a series of body-on-frame open two-seater sports cars that were produced by MG from 1936 to 1955. The series included the MG TA, MG TB, MG TC, MG TD, and MG TF Midget models. The last of these models, the TF, was replaced by the MGA. Although the design was similar to contemporary cars of the 1930s, it came to be considered outdated by the 1950s.

The 1950 TD Midget announced in January 1950[9] combined the TC’s drivetrain, a modified hypoid-geared rear axle, the MG Y-type chassis, a familiar T-type style body and independent suspension on front axle using coil springs from the MG Y-type saloon: a 1950 road-test report described as “most striking” the resulting “transformation … in the comfort of riding”. The reference cited here was incorrect to infer the entire drive train was lifted from the TC, as along with the new hypoid differential, a completely different transmission was used (albeit also a four-speed). Also lifted from the company’s successful 1¼-litre saloon was the (still highly geared) rack and pinion steering. In addition the TD featured smaller 15-inch (380 mm) disc type road wheels, a left-hand drive option and standard equipment bumpers and over-riders. The car was also 5 inches (130 mm) wider with a track of 50 inches (1,300 mm). It was seen by enthusiasts at the time as a disappointment, mild and “not a sports car”. “. . . the new model is largely designed to consolidate and expand the car’s sale in North America.” The first TDs were actually built in late 1949.
