A pass rate records whether cars met the roadworthiness standard on test day. It is not a reliability score, and part of any gap reflects how old the tested cars were.
6 Series MOT pass rate by age
The same 2025 tests split by the car's age at test.
BMW 6 Series cars aged 3 to 5 years passed 87.8% of MOT tests. For cars aged 11 years and over that fell to 75.7%, a drop of 12.1 percentage points.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 3 to 5 years | 844 | 87.8% | 15.5 pts above |
| 6 to 10 years | 8,716 | 84.2% | 11.9 pts above |
| 11 years and over | 12,110 | 75.7% | 3.4 pts above |
That is a steep decline with age, so the headline rate flatters older examples. The UK average of 72.3% covers cars of every age, so compare like with like.
