Advanced High Strength Steel (AHSS).

Thanks to heat treatment processes, Advanced High Strength Steel (AHSS) is up to 10% lighter than, and twice as rigid, as conventional mild steel.

The all-new i30 features significantly increased application of AHSS, totalling 53.5% (as compared to 27.2% on the outgoing model), and resulting in a significant increase in static rigidity over the outgoing model, whilst achieving a 28kg lighter body-in-white weight.
