Magazine tests
Published braking distances (Auto Bild, auto motor und sport, Auto Zeitung, ADAC, Za Rulem and others). Rank = position in the same test on the same surface (1 = shortest). The tests use different sizes, cars and conditions, so only compare numbers within the same test.
| Test | Size | Conditions | Result | Rank | Best |
|---|---|---|---|---|---|
| Auto Bild 2025 | 225/40 R18 | dry asphalt 100→0 km/h | 36.9 m | 31 / 52 | 32.6 m |

The calculation on this page does not use these results: our check showed that a test in another size does not predict wet braking better than the EU label for your size. They are shown here as measured facts.
