The MG T series of cars (including the TA, TB, TC, TD, and TF) was a basic body-on-frame convertible sports car produced from 1936 through to 1955. It was replaced by the MGA.

TA

The MG TA replaced the PB in 1936. It was an evolution of the previous car and was wider in its track at 45 inches and longer in its wheelbase at 94 inches. The previous advanced overhead cam engine was now not in use by any other production car so it was replaced by a more typical MPJG OHV unit from the Wolseley 10 but with twin SU carburettors, modified camshaft and manifolding. The engine displaced just 1292 cc, with a stroke of 102 mm and a bore of 63.5 mm and power output was 50 hp (40.3 kW) at 4500 rpm. The four speed manual gearbox now had synchromesh on the two top ratios. Like the PB, most were two seat open cars with a steel body on an ash frame but it could also be had from 1938 as a Tickford drophead coupé with body by Salmsons of Newport Pagnellmarker or closed "airline" coupé as fitted to the P type but only one of these is thought to have been made. It was capable of reaching nearly in standard tune with a 0-60 mph time of 23.1 seconds. Unlike the PB, hydraulic brakes were fitted. Just over 3000 were made and in 1936 it cost £222 on the home market.

TB

The TA was replaced by the TB in May 1939 with the fitting of a smaller but more modern XPAG engine as fitted to the Morris 10 but in a higher tuned state and like the TA with twin SU carburettors. This 1250 cc I4 unit featured a slightly less-undersquare 66.6 mm bore and 90 mm stroke and had a maximum power output of at 5200 rpm. Available as either an open 2 seater or more luxurious Tickford drophead coupé, this is the rarest of the T type cars with only 379 made.

TC

The TC was the first postwar M.G., launched in 1945. It was quite similar to the pre-war TB, sharing the same pushrod-ohv engine with a slightly higher compression ratio of 7.4:1 giving at 5200 rpm but using more modern interior elements allowing a wider cockpit. The makers also provided several alternative stages of tuning for "specific purposes". It was exported to the United States, even though only ever built in right hand drive. The export version had slightly smaller US specification sealed beam head lights and larger twin rear lights, as well as turn signals and chrome-plated front and rear bumpers. Exactly 10,000 production versions were produced, from Sept. 1945 (chassis # TC0251) to Nov. 1949 (chassis # TC10252), a larger number than any previous M.G. model. It cost £527 on the home market in 1947.

TD

The 1950 TD combined the TC's drivetrain but with modified hypoid geared rear axle with the MG Y-type chassis and a familiar T-type style body. An independent suspension using coil springs in front was new, based on that fitted to the MG Y-type saloons, as were rack and pinion steering, smaller disc type road wheels and a left-hand drive option. Bumpers and over-riders became standard for the first time. The car was also wider with a track of .

In 1950 the TD MkII was introduced, produced alongside the standard car, with a more highly tuned engine with 8.0:1 compression ratio giving at 5500 rpm. It also featured twin fuel pumps revised dampers and a higher rear axle ratio

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 were exported to the United States.

An example tested by The Motor magazine in 1952 had a top speed of and could accelerate from 0- in 18.2 seconds. A fuel consumption of was recorded.

In 1998, the rights, intellectual properties and trade marks associated with the production of MG TD is acquired by TD Cars Sdn Bhd in Malaysia to reproduce the TD series as TD2000.

TF and TF 1500

The TF was essentially a stop-gap car to keep production going until the new MGA could be approved for production by the BMC hierarchy which did not want a car that would compete with the newly-announced Austin-Healey. The TF launched in 1953 was a facelifted TD, fitted with the TD Mark II engine, a sloping radiator grille and the headlights in the wings. The external radiator cap was now a dummy as a pressurised cooling system was fitted to better cope with hot climates.

In 1954 the engine was re-designated XPEG and enlarged to 1466 cc by increasing the bore to 72 mm giving at 5,000 rpm and the car was designated the "TF1500".

Production ended on 4th April 1955 after 9602 TFs were made, including two prototypes and 3400 TF1500s. The TF was superseded by the MGA.

The TF name was reused in 2002 on the mid-engined MG TF sports car.
