Nearly 30,000 TDs had been produced, including about 1700 Mk II models, when the series ended in 1953 with all but 1656 exported, 23,488 of them to the US alone.
The 1950 TD Midget announced in January 1950 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”.
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.
