How do I tell a 1950 MG TD from a 1951 or 1952 car?

Read the engine prefix and look at the clutch. A 1950 car should carry a plain XPAG/TD prefix and the seven-inch dry-plate clutch; the XPAG/TD2 prefix and the eight-inch clutch came in from around engine 9408 in mid-1951, and the Mark II (TD/C) with its XPAG/TD3 engines belongs later still. Because engines were swapped freely, treat the prefix as a strong clue and confirm the despatch date against the MG Car Club T Register factory record.

What is the chassis number range for a 1950 MG TD?

TD car numbers run from 0251 to 29915 across the whole 1949–1953 run, issued with gaps, and MG never published a per-year breakpoint. A 1950 car will be low in that band, but no published range defines the year — the factory production record is the only way to fix a despatch date.

Was the 1950 MG TD available in left-hand drive?

Yes. The TD was the first T-Type built left-hand drive at the factory, and left-hand-drive engine numbers carry the LHX insert, for example XPAG/TD/LHX4950. A left-hand-drive TC, by contrast, is always a conversion.

The TD's first full year

The MG T-Series in 1950

1950 is the MG TD's first full year: the familiar 1,250 cc XPAG engine in a substantially modernised chassis with independent front suspension, rack-and-pinion steering, bolt-on 15 in disc wheels and, for the first time, factory left-hand drive. Around 29,664 TDs were built to 1953.

Production notes

A 1950 TD is an early car: the XPAG/TD2 engine prefix and eight-inch clutch did not arrive until around engine 9408 in mid-1951.
The Autocar tested the TD in its issue of 20 January 1950 and recorded a genuine top speed of over 80 mph.
TD car numbers run from 0251 to 29915 with gaps, so the number alone does not give a year — the engine prefix is often the better clue.

Engine and chassis traits

Early XPAG/TD engine and seven-inch clutch

An original 1950 car carries a plain XPAG/TD prefix — no 2 or 3 — and the earlier seven-inch dry-plate clutch. The eight-inch clutch came with the TD2 engine change in mid-1951.

Independent front suspension and rack-and-pinion steering

The TD's box-section chassis carries coil-and-wishbone independent front suspension derived from the Y-Type and rack-and-pinion steering, on bolt-on 15 in disc wheels with 5.50–15 tyres. Look underneath at the frame below the rear spring hangers, where TD cracking is well documented.

What changed in 1950

First full year of the new chassis

1949 saw only the very start of TD assembly, so 1950 is the first year in which the box-section frame, coil-and-wishbone independent front suspension taken from the Y-Type and rack-and-pinion steering were built in volume. Anyone comparing a TD with a TC is comparing 1950 engineering with 1936 engineering.

Factory left-hand drive, and the export car

The TD was the first T-Type built left-hand drive at Abingdon rather than converted afterwards. That is the single change with the biggest consequence for a 1950 car: most surviving early TDs went abroad, and their engine numbers carry the LHX insert.

Bolt-on disc wheels instead of wire

Where the TC ran 19 in centre-lock wire wheels, the TD uses bolt-on 15 in steel disc wheels with 5.50–15 tyres. Wire wheels on a TD are an aftermarket fitment, not a 1950 factory option.

What had not yet changed

The seven-inch dry-plate clutch and the plain XPAG/TD engine ran through 1950; the eight-inch clutch and XPAG/TD2 prefix came in from around engine 9408 in mid-1951. So the clutch and the prefix are the two most useful dated anchors for separating a 1950 car from a 1951 one.

How the press saw it

The Autocar tested the TD in its issue of 20 January 1950 and recorded a genuine top speed of over 80 mph — a contemporary figure worth holding on to when a seller quotes performance claims.

Reading the numbers on a 1950 car

Chassis: TD25509 or TD/C22580. Engine: XPAG/TD/… with slashes and no spaces.
Left-hand-drive TD engine numbers are prefixed LHX, for example XPAG/TD/LHX4950.

Only the MG Car Club T Register factory production records give an exact despatch date. Enter your numbers in the dating tool for a likely span first, then confirm it against that record.

Number bands for a 1950 car

What	Reading	Notes
TD car numbers (whole model run)	0251 – 29915	Issued with gaps across 1949–1953, which is why the range is wider than the roughly 29,664 cars built. MG published no yearly breakpoint, so a number on its own never proves a 1950 build.
1950 engine prefix	XPAG/TD/…	Plain TD, with no 2 or 3. The XPAG/TD2 prefix arrived from around engine 9408 in mid-1951, so a TD2 or TD3 block in a car sold as a 1950 model is a later engine.
1950 left-hand-drive engines	XPAG/TD/LHX…	The LHX insert marks a factory left-hand-drive engine — new for the TD, and the reason the model sold in the numbers it did.
What 1950 rules out	No TD/C, no TD2, no TF	Mark II (TD/C) cars belong to the later part of the run, and the TF was not launched until 15 October 1953. Any of those features on a claimed 1950 car needs explaining.

1950 cars in the registry

No verified 1950 car is recorded in the registry yet. If you own one, add it to the registry — chassis and engine numbers from real cars are how a year like this gets properly documented.

1950 questions

How do I tell a 1950 MG TD from a 1951 or 1952 car?: Read the engine prefix and look at the clutch. A 1950 car should carry a plain XPAG/TD prefix and the seven-inch dry-plate clutch; the XPAG/TD2 prefix and the eight-inch clutch came in from around engine 9408 in mid-1951, and the Mark II (TD/C) with its XPAG/TD3 engines belongs later still. Because engines were swapped freely, treat the prefix as a strong clue and confirm the despatch date against the MG Car Club T Register factory record.
What is the chassis number range for a 1950 MG TD?: TD car numbers run from 0251 to 29915 across the whole 1949–1953 run, issued with gaps, and MG never published a per-year breakpoint. A 1950 car will be low in that band, but no published range defines the year — the factory production record is the only way to fix a despatch date.
Was the 1950 MG TD available in left-hand drive?: Yes. The TD was the first T-Type built left-hand drive at the factory, and left-hand-drive engine numbers carry the LHX insert, for example XPAG/TD/LHX4950. A left-hand-drive TC, by contrast, is always a conversion.
Did the 1950 MG TD have wire wheels?: No. The TD left Abingdon on bolt-on 15 in steel disc wheels with 5.50–15 tyres. Wire wheels seen on a TD today are a later fitment.
