How Porsche models compare on the MOT
The spread across Porsche models is wide — 96.8% for the 718 Cayman GT4 at the top and 86.8% for the Boxster at the bottom, a 10.0-point gap across 2,026 and 99,894 recorded tests respectively. Most Porsche models sit much closer to the middle (around 91.0%, on 121,590 tests for the 911). The best and worst are both real DVSA results, not opinions: the pass rate is the share of every completed MOT test for that model that ended in a pass.
Every figure above is drawn from the DVSA's class-4 MOT records for the 2000–2023 data years: 517,789 tests across 25 Porsche models. A pass rate counts every completed test — first attempt and retests — so the figures above include a van or motorhome being tested twice in one year. The first-time pass figures on each model page are lower as a result. See the methodology page for exactly how each rate is calculated and how the DVSA source data is filtered.

Fewer than 2,000 tests each, so they are not ranked — every model still has its own pass-rate page.

Reading the numbers
A pass rate covers every completed test recorded for that model and year, including retests. First-attempt figures are lower. See how we calculate.
