Verdict

The Porsche Taycan passes its MOT first time on 90.4% of tests, 2.6 points higher than a typical car of the same age and mileage (87.7%). That puts it ahead of 81% of cars on UK roads once age and mileage are taken into account.

By year of first registration, the 2021 Taycan does best (beats 86% of cars) and the 2022 worst (beats 71%).

The MOT doesn’t test an electric car’s battery or motor, so ask for a battery health report too, and electric cars have no exhaust emissions test, which flatters the comparison a little.

Better than average on lights & electrics, visibility, brakes.

Engines

All years, most common first. Grades compare each car with cars of the same age and mileage (A = best 20% of cars on UK roads, E = worst 20%), so an older or higher-mileage car can grade above one with a higher pass rate.

Buying one or MOT due? Check these

  • Tyre damage & cracking 1.8× typical
    Look for cuts, bulges and cracking on both sidewalls of every tyre.
  • Tyre tread depth
    Check every tyre, including the inner edge, has at least 3 mm of tread. Uneven wear can point to alignment or suspension problems.
  • Headlight aim
    Park facing a wall at night: both dipped beams should sit level and dip to the left.
  • Windscreen washers
    Test the washers and wipers: a cheap fix, but a very common MOT fail.
  • Tyre pressure warning (TPMS)
    Make sure no tyre-pressure warning light stays on after start-up.
  • Suspension ball joints
    Listen for knocks over speed bumps and feel for wandering or vague steering.

Differences also reflect how cars are used and maintained, not only how they are built.
