Hankook launched the Ventus iON S, the first summer tyre in a new product range that has been specifically designed for electric vehicles.
Hankook Introduced the Ventus iON S for E-Cars
Hankook intends to make a decisive contribution from a tyre choice perspective to advancing the mobility transition towards zero-emission vehicles. The new summer tyre is a pioneer of the new, global “iON” tyre family designed for premium electric vehicles. Characteristics of the new tyre include reduced rolling resistance, extremely low noise rolling characteristics and high load-bearing capacity. For drivers of electric cars, this means more range per battery charge and a better driving experience compared to conventional tyres. In addition, the new Hankook iON products are specially designed for the instant high torques produced by powerful electric vehicles.
The new Hankook Ventus iON S meets the demanding everyday requirements for EV tyres by providing an extensive set of technical measures. In particular, Hankook has countered the higher vehicle mass of electric vehicles caused by the considerable weight of the drive batteries with a higher load capacity. Among other things, ultra-resistant aramid fibres effectively counteract the deformation forces caused by the especially high torque in electric vehicles. The tread compound, which features a high proportion of natural resin, also ensures exemplary durability and reduced wear. The high silica content provides micro-level grip on wet roads by counteracting the formation of a film of water between the road surface and the tyres, which can be dangerous.
Another special feature of the new compound is its high proportion of natural oils. This not only makes the iON products more sustainable overall, but it also has a positive impact on the durability of the tread. This means that less material is required for consistent performance, and the savings in weight of up to one kilogram per tyre improves rolling resistance. One of the special features of the Ventus iON S is the aerodynamic optimisation so that it can exploit potential for greater levels of efficiency and range. The tyre pattern is designed in such a way that air resistance is reduced, something that is even true for the lettering on the tyre sidewalls.
A further development goal was to achieve the quietest possible running characteristics, especially since eliminating the noise of an internal combustion engine draws attention to this aspect. It is therefore all the more important that Hankook’s integrated Sound Absorber technology, together with the noise-reducing tyre pattern, noticeably reduces the level of noise inside the vehicle. Hankook engineers resolved the conflicting objectives of minimising rolling resistance while maintaining the same quality in other important performance criteria. This has also been certified by TÜV SÜD in an independent comparative test using competitor products from the premium segment. Mounted on common premium electric vehicles, the Hankook Ventus iON S is clearly superior, without showing weakness in other important criteria.
Hankook iON tyres make it possible to drive more kilometres per battery charge compared to standard tyres, they can also make a significant contribution to reducing CO2 emissions from road traffic. The Hankook Ventus iON S is available in sizes between 18 and 22 inches. Hankook development engineers documented their expertise in this demanding segment many times over. Original equipment tyres from Hankook that have been optimised for electromobility are already being used by Audi, BMW, Porsche, VW and other leading brands. From the 2022/2023 season, the Hankook will also be demonstrating the technical expertise it has acquired in the area of sustainability and high-performance mobility, as a supplier in the world of electric motorsport, as appointed by the Fédération Internationale de l’Automobile (FIA).
