Porsche Taycan Gets Special Optimized Tires From Hankook07/11/2020
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:
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.”
