Hankook Tire is supplying its Ventus S1 evo 3 ev e-tires as original equipment tires to e-tron GT, Audi’s first all-electric sports car.

Hankook is fitted on the Audi e-tron GT ex works with its Ventus S1 evo 3 ev, which has been specially developed for the needs of electric vehicles. In size 225/55R19 XL 103Y on the front axle, 275/45R19 XL 108Y on the rear axle, the Ventus S1 evo 3 ev is host to many technical refinements that help to optimally bring the performance of electrically powered sports cars to the road.

“The development of an e-tire is particularly complex,” explains Moonhwa Hong, Vice President of OE Development Department. “Therefore, it is now paying off that we expanded research in this area early. Our company is now represented on several premium models in the electric sports car segment, including the Audi e-tron GT, and has established a very good position in this segment overall.”

For the Audi e-tron GT, the tread pattern of the Ventus S1 evo 3 has been adapted especially for electric vehicles to reduce tire noise by approximately three decibels. This is important, as engine noise in electric vehicles is omitted, so road and tire noise inside the vehicle is perceived as louder. In addition, in order to cope with the high stresses caused by the high performance of electric sports cars, the tire is reinforced with so-called bead-packing technology, as well as a high lateral stiffness for particularly precise handling even at high speeds. In addition to supporting sporty characteristics, Hankook’s EV tire is also an important component for comfort, as Grand Turismos like the Audi e-tron GT are designed to enable comfortable travel even on long journeys.

“Our tire has to bring the very high drive power of the Audi e-tron GT to the road and at the same time deliver the low rolling resistance that is a key factor in electric vehicles, for high efficiency and range,” says Jeongho Park, Executive Vice President and Director of OE Division, “We can be proud of the result.”
