Hankook Tire to equip Toyota’s first all-electric vehicle bZ4X
- Ultra-high performance EV tire Ventus S1 evo 3 ev fitted to realize maximum driving potential
- Hankook Tire furthers partnership with Toyota and expands original equipment portfolio for EVs
Seoul, Korea, January 12, 2023 – Global leading tire company Hankook Tire is equipping Toyota’s first ever all-electric vehicle, Toyota bZ4X, in the Chinese market from last June. Hankook Tire’s Ventus S1 evo 3 ev will be available for fitment in the sizes 235/60R18 and 235/50R20.
Hankook Ventus S1 evo 3 ev is equipped ex works to maximize the electric SUV’s full potential. For an EV with long range, the reduction of the tire’s rolling resistance is a key factor for maximizing fuel efficiency. The Ventus S1 evo 3 ev demonstrates abrasion performance improved by 5 percent and rolling resistance reduced by 13 percent compared to the conventional model through the vulcanization process optimization applied in its compound development.
While lowering rolling resistance, the tread compound of the Ventus S1 evo 3 ev has also been adapted to the needs of very high drive torque unique to an EV. It features a double-layer carcass made of a specially developed high-performance fiber as well as bead-packing technology, offering high stability with a low tare weight relative to its size. The engineers also designed the inner construction of shoulder areas in a way to maximize traction at the beginning of the movement.
Another advantage the Hankook Ventus S1 evo 3 ev brings is noise reduction. With the absence of noise from the internal combustion engine in an EV, road noise inside the vehicle can stand out. In assistance of a more comfortable driving experience, Hankook Ventus S1 evo 3 ev has been designed to reduce tire noise by approximately three decibels.
As a pure electric compact SUV offering superior power efficiency and delivering more than a 500 km drive on a single full charge, Toyota bZ4X realizes its full potential with the equipment of Hankook Ventus S1 evo 3 ev. The tire can assist versatility of the bZ4X for urban cityscape and off-road driving and provide a relaxing and quiet space.
