The TA Midget replaced the PB in 1936. It was an evolution of the previous car and was 3 inches (76 mm) wider in its track at 45 inches (1,100 mm) and 7 inches (180 mm) longer in its wheelbase at 94 inches (2,400 mm).
The previous advanced overhead-cam inline-four engine was by then not in use by any other production car so it was replaced by the MPJG OHV unit from the Wolseley Ten, but with twin SU carburetors, modified camshaft and manifolding. The engine displaced just 1292 cc, with a stroke of 102 mm (4.0 in) and a bore of 63.5 mm (2.5 in) and power output was 50 hp (40.3 kW) at 4,500 rpm. The four-speed manual gearbox now had synchromesh on the two top ratios and was connected to the engine by a cork-faced clutch running in oil. Unlike the PB, hydraulic brakes were fitted with 9-inch (230 mm) drums.

Like the PB, most were two-seat open cars with a steel body on an ash frame. A bench-type seat was fitted with storage space behind.
The T-type was capable of reaching almost 80 mph (130 km/h) in standard tune with a 0–60 mph time of 23.1 seconds. Allan Tomlinson won the 1939 Australian Grand Prix handicap driving an MG TA.
