Porsche Taycan Gets Special Optimized Tires From Hankook

The stake is high, and every percent of efficiency counts, so you can't just fit a proprietary BEV with conventional tires.

The first series-produced all-electric Porsche, the Taycan, is a challenging EV as it needs to offer high-performance, but at the same time, remain efficient to not compromise the range.

One of the ways to address all the requirements and maximize the result is to develop proprietary parts, including tires. In the case of tires, the Taycan can be equipped with specially developed Hankook Ventus S1 evo 3 ev e-tyres.

"Premium tyre maker Hankook is contributing to the Porsche Taycan with its Ventus S1 evo 3 ev, which has been specially developed for the needs of electric vehicles. In the size 225/55R19 XL 103Y on the front axle, 275/45R19 XL 108Y on the rear axle and “NF0” on the sidewall, the Ventus S1 evo 3 ev hides a lot of technical refinements that bring the performance of electronically driven sports cars optimally onto the road."

Several things differ in this proper EV tire, as compared to the conventional version for internal combustion cars:

the tread pattern, adapted from the standard Ventus S1 evo 3, was modified to reduce tyre noises, that would be annoying in a quiet EV
for high performace, "the tyre has a reinforced bead with so-called bead-packing technology, as well as high lateral stiffness for precise handling even at high speeds"
improved rolling resistance (13% lower overall), durability (by up to 30%) and abrasion resistance (by 5%)

It seems that the tire manufacturers are now busier than ever, as they have to develop completely new products, rather than just tweak current models. EVs are usually heavier than ICE, have high torque and the low rolling resistance is valued higher. That's just a few things among others that changes a lot when it comes to tires.

"To meet the specific demands of an electric vehicle such as the Porsche Taycan, Hankook’s developers have also discovered an optimally balanced vulcanisation process for the tyre 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."

Hankook supplies special e-tyres for Porsche Taycan electric sports cars

Tyre maker Hankook is further expanding its original equipment commitment to the Stuttgart sports car manufacturer and, with its specially developed Ventus S1 evo 3 ev e-tyres, is now also supplying the new Porsche Taycan, the first all-electric sports car from Porsche AG.

Neu-Isenburg, Germany, July 9, 2020 – Premium tyre maker Hankook is contributing to the Porsche Taycan with its Ventus S1 evo 3 ev, which has been specially developed for the needs of electric vehicles. In the size 225/55R19 XL 103Y on the front axle, 275/45R19 XL 108Y on the rear axle and “NF0” on the sidewall, the Ventus S1 evo 3 ev hides a lot of technical refinements that bring the performance of electronically driven sports cars optimally onto the road.

“We are proud to equip the first fully electric sports car from Porsche with our tyres. 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.

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 tyre 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 tyre has a reinforced bead with so-called bead-packing technology, as well as high lateral stiffness for precise handling even at high speeds.

“With the tyre 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”, explains Dipl.-Ing. Klaus Krause, head of the European research and development centre at Hankook.

To meet the specific demands of an electric vehicle such as the Porsche Taycan, Hankook’s developers have also discovered an optimally balanced vulcanisation process for the tyre 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.
