To meet the needs and driving dynamics of electric vehicles, tire maker Hankook has developed its Ventus S1 evo 3 ev range, to reduce road noise and improve resistance for the high speed and torque delivered from EVs.
The new tire will feature on the Porsche Taycan, the brand’s first all-electric sports car. The tread pattern of the Ventus S1 evo 3 was adapted in the ev version for Porsche in such a way that it reduces in particular those tire noises which may be perceived as annoying in the vehicle interior due to the absence of engine noise by about three decibels. To meet the heavy demands of the high performance of electric sports cars, the tire has a reinforced bead with so-called bead-packing technology, as well as high lateral stiffness for precise handling even at high speeds.
“We are proud to equip the first fully electric sports car from Porsche with our tires. Providing the original equipment for sporty premium vehicles is already a tradition at Hankook. Our engineers have shown that with our products we are well prepared for the new demands in the field of electric sports cars and are therefore well positioned for the future,” says Sanghoon Lee, president of Hankook Tire Europe.
To meet the specific demands of an electric vehicle such as the Porsche Taycan, Hankook’s developers have also discovered an optimally balanced vulcanization process for the tire compound that ensures the right balance of temperature, time expenditure and pressure. As a result, Ventus S1 evo 3 ev achieves 30% greater durability compared to a standard tread compound. Abrasion resistance has been improved by 5% compared to the conventional model and rolling resistance has been improved by 13% overall.
“With the tire development for the Porsche Taycan, our development team has moved into completely new dimensions and we are proud of the result. For the original equipment engineers, such a development project represents a special challenge – because solving the conflict of objectives for optimizing the various performance criteria in an e-vehicle like this high-performance sports car requires the highest level of expertise and the latest technologies,” explained Klaus Krause, head of the European research and development center at Hankook.
