Taycan 4x2: a strong MOT record by UK norms
Across 2,160 MOT tests, the Taycan 4x2 returns 92.9% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a tyre with the cords showing. Tyre tread under the limit and windscreen damage round out the top three. Average tested mileage sits at 25,305, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping a Taycan 4x2?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Taycan 4x2 and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
