Where Porsche ranks among 33 makes
Younger fleets pass more often, so a raw pass rate flatters makes with newer cars on the road. We gave every make with 50,000 tests or more the same age profile as the whole fleet, then ranked them. Porsche came 1 of 33.
| Make | Pass rate allowing for age |
|---|---|
| Porsche (position 1) | 88.8% |
| Lexus | 83.9% |
| Tesla | 82.0% |
| Jaguar | 78.8% |
| BMW | 78.7% |
| Honda | 78.2% |
| Land Rover | 77.8% |
The straight first-time pass rate for all makes was 72.3%. The ranking compares test results only. It says nothing about breakdowns or repair bills.
Porsche pass rates as cars get older
At 3 years old, Porsche's first-time pass rate was 93.0%, against 88.5% for all makes of the same age. At 20 years it was 81.1%, against 57.6%. Porsche beat the all-make figure in every age group shown, and the gap was widest at 15 years (28.6 points ahead).
| Age | Porsche tests | Porsche first-time pass | All makes, same age |
|---|---|---|---|
| 3 years | 15,829 | 93.0% | 88.5% |

What Porsche cars failed on most
The five items testers wrote down most often when a Porsche failed. Each figure is a share of all failure items, not of tests, and one failed test can list several. Four of the five show up more often on Porsche cars than across all makes. The biggest difference is windscreen or window damage: 7.52% of Porsche failure items, against 4.19% overall.
| Failure item | Porsche | All makes | |
|---|---|---|---|
| 1 | Windscreen or window damage: Windscreen or window damaged or seriously discoloured but not adversely affecting driver's view | 7.52% | 4.19% |
| 2 | Tyre seriously damaged: A tyre seriously damaged | 6.40% | 3.57% |
| 3 | Tyre tread below the requirements: Tyre tread depth not in accordance with the requirements | 4.79% | 3.74% |
| 4 | Rear registration plate light not working: A rear registration plate lamp or light source missing or inoperative in the case of multiple lamps or light sources | 4.38% | 4.98% |
| 5 | Headlamp aim outside the requirements: The aim of a headlamp is not within limits laid down in the requirements | 4.30% | 2.84% |
Porsche MOT pass rates by model
6 Porsche models had 5,000 tests or more, enough to compare. Highest: MACAN, 90.7% from 34,438 tests. Lowest: BOXSTER, 82.6% from 32,098 tests.
Model rates are not adjusted for age, so a model with mostly older cars on the road will look worse. Class 4 also covers taxis and some light vans, which can appear in the list.
| Model | First-time pass | Tests | Position |
|---|---|---|---|
| MACAN | 90.7% | 34,438 | 1 |
| CAYMAN | 88.9% | 14,285 | 2 |
| 911 | 88.4% | 46,090 | 3 |
| PANAMERA | 88.3% | 6,659 | 4 |
| CAYENNE | 84.8% | 29,012 | 5 |
| BOXSTER | 82.6% | 32,098 | 6 |

The car passed at its first test, with nothing repaired at the test centre and no retest.
Can I see a Porsche's MOT history for free?
Yes. Enter the registration on our home page to see its passes, fails, advisories and recorded mileage.
What does a history report add?
The checks an MOT record cannot show: finance still owed, theft and write-off records, salvage history, mileage, recalls and a valuation.
How we worked out these figures
We used DVSA's anonymised records of Class 4 MOT tests in Great Britain from 1 January to 31 December 2025, keeping first tests and leaving out retests, abandoned and aborted tests.
- Clean pass: passed at the first test with nothing fixed at the test centre
- Passed after a repair: a fault was fixed at the test centre during that first test
- Tests counted: clean passes, fails and passes after a repair at the first test
- Repair share: passes after a repair as a percentage of the tests counted
- Class 4: cars, taxis and some light vans
- Makes compared: at least 50,000 tests
- Models compared: at least 5,000 tests
- Age groups shown: at least 300 tests
- Fault figures: a share of failure items, not of tests
- Age adjustment: our own method, not a DVSA statistic
