TD2 and the eight-inch clutch
The MG T-Series in 1951
Mid-1951 brings the T-Series' clearest dated engine change: from around engine 9408 the TD's prefix became XPAG/TD2, adopted with the larger eight-inch clutch. A car with a TD2 engine is therefore very unlikely to be a 1950 build, which makes the prefix a useful dating clue.

Production notes
- The XPAG/TD2 prefix came in from around engine 9408 in mid-1951, with the larger eight-inch clutch.
- Engines were replaced often over seventy years, so treat the prefix as a clue to the car's period rather than proof of its build date.
- TD numbers were not used consecutively without gaps, which is why the car-number range is wider than the production total.
Engine and chassis traits
XPAG/TD2 and the eight-inch clutch
From around engine 9408 in mid-1951 the TD used the XPAG/TD2 prefix and an eight-inch dry-plate clutch in place of the earlier seven-inch unit.
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.
Reading the numbers on a 1951 car
- Engine: XPAG/TD2/23015 — slashes, no spaces.
- TD/C in a chassis number is the Mark II designation, not the TD2 engine prefix. The two are routinely confused.
