Performance Analysis

Hankook iON FlexClimate - Official Image

Across the two available EV-focused all-season tests, the Hankook iON FlexClimate shows consistently class-leading overall performance, winning both tests (1/3 in the 2025 Auto Bild EV all-season mini-test and 1/5 in the 2025 TUV EV report). The dominant pattern is very strong wet performance (regularly 1st place across wet braking and aquaplaning metrics) paired with top-tier dry performance (including multiple 1st place results), making it an exceptionally balanced all-season option for EV applications.

The main trade-off versus best-in-test rivals appears in snow traction/handling where it tends to sit just off the top spot (commonly 2nd place and a few percent behind the best). Efficiency/rolling resistance is competitive but not class-leading in the only test where it was measured, suggesting that while energy performance is good, its standout advantage is grip and safety, especially in wet conditions.
