The Ventus S1 Evo Z marks a new era in Hankook’s high-end-tyre portfolio streamlined for highly demanding sports cars that need the extra bit of grip and cornering qualities, without compromising durability and safety.
Hankook says a focus when developing the Ventus S1 evo Z was on high grip in different weather conditions. For this UUHP (Ultra-Ultra-High-Performance) tyre, Hankook developed a new silica enriched compound mixture with the latest generation of functional polymers, a technology originating from their racing tyre development.
This compound undergoes a slower curing process with low temperature vulcanisation to increase the blending of those molecules that then influences the driving performance.
This ensures a consistently high level of grip across a wide range of applications and the result is a tread compound which is bespoke for sports cars of premium manufacturers, representing the top of their range.
Often seen with particularly sporty treads, the Hankook Ventus S1 evo Z also uses an asymmetrically designed tread pattern. The arrangement of the individual tread blocks has been developed to ensure optimum block stiffness under various driving conditions.
Three main drainage grooves positioned in the inner tread area ensure water is drained efficiently in wet conditions. In addition, special attention has been paid to the outer tread area of the tyre, where a significantly increased proportion of tread delivers the requirements for high-performance cornering and precise lateral guidance, particularly for very sporty driving in dry conditions.
For this highly demanding vehicle segment, especially when it comes to tyres, the Ventus S1 evo Z is equipped with an aramid composite material in a double-layer carcass. This prevents deformations caused by possible heat development during extensive use improving the rolling circumference and the precision handling at high speeds.
Aramid fibres are extremely heat-resistant and are characterised by their very high strength as well as good damping properties with a low weight relative to their size. The new Hankook tread pattern gains additional stability from high-strength steels in the belt and bead areas, which, in combination with the reinforced sidewall, ensure straight-line stability and steering precision, as well as sporty, dynamic handling.
Hankook’s Ventus S1 evo Z is original equipment on the BMW X3 M and X4 M, the MINI John Cooper Works GP and the Porsche Panamera and while being extra sporty, this high performance tyre also offers a reasonable amount of comfort.
These Hankook tyres are currently available in over 15 sizes ranging from 18 to 21 inches in aspect ratios of 35 to 45, with tread surface widths of 225 to 315mm, and speed class Y.
