The picture
Across 666 MOT tests, the Taycan Turbo returns 88.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a tyre with the cords showing. Windscreen damage and a non-conforming number plate round out the top three. Average tested mileage sits at 21,328, 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.
