Performance Analysis
Across three summer-focused tests, the Hankook iON Evo consistently delivered class-leading dry and wet on-road performance with strong efficiency. It won two of three tests and averaged 1.3 overall, repeatedly topping braking and handling while maintaining low rolling resistance and competitive noise/comfort. Aquaplaning resistance and value/range trade-offs appeared as the primary compromises depending on test context and size.
Key strengths are short braking distances and high cornering/handling speeds in both dry and wet, plus best-in-test rolling resistance in two studies. Weaknesses cluster around aquaplaning performance and, in one EV-specific test, value/range metrics versus the very best.
