Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 0.4% of tests record it — this model is 5.3× that share |
| The 159 models compared | 19 of 159, highest first |
| The model's own record | 888,073 tests · every year of the A4 → |
A share of tests is not a probability for your car: it counts every Audi A4 tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
