The 'EV4' is the only electric sedan in the Kia EV series. It is a long-range model with an 81.4kWh battery based on a 17-inch wheel, and has recently attracted attention for suggesting the direction of next-generation electric sedans with up to 533 kilometers of mileage per charge, cutting-edge driving technology, and future-oriented design, along with the original performance of high-performance electric vehicles.
Ion Evo AS, which will be mounted on the EV4 model, is a product developed with the design of Ion Innovative Technology, a unique electric vehicle-specific technology. The driving performance of the high-performance electric sedan is more precisely completed by achieving an optimal balance of core performances such as excellent overall efficiency, grip, mileage, low noise, and low rotational resistance.
First, the rotational resistance, which greatly affects the driving distance of the electric vehicle, is drastically reduced and ideal overall efficiency is provided. By applying the latest compound exclusively for electric vehicles that combine eco-friendly materials and high-concentration silica and optimal low-temperature uniform rubber curing technology (Curing Technology), it reduces battery consumption of "EV4" vehicles that boast the largest mileage in the Kia EV series and fully supports long-distance driving.
In addition, the adoption of an optimal electric vehicle compound and a 3D grip control sip provides excellent grip and handling performance on dry, wet and winter snow, and supports a stable driving experience throughout the four seasons.
The low-noise specialized design provides a comfortable ride in all speed ranges. Through Knurling technology that narrows the air path of the main groove (the thick vertical groove of the tire surface) and optimal arrangement of tire blocks, noise generated on the road surface was drastically reduced to achieve the best low-noise environment.
In addition, the optimal profile design evenly distributes tire ground pressure even in high loads of vehicles equipped with large-capacity batteries to prevent abnormal wear and tear, and strengthens transverse stiffness and cornering stiffness by 25% and 20%, respectively, to achieve excellent driving stability even at high speed.
With this supply of new tires, Hankook Tire has greatly strengthened its status as a key facilitator of Kia's electric project. Following the electric SUVs 'EV9' and 'EV3', it continues to expand its portfolio to the sedan model 'EV4' and is recognized for its innovative technology that leads the global electric vehicle tire market.
In the future, Hankook Tire plans to strengthen its leading position in the electric vehicle tire market by focusing on securing future mobility source technologies through cutting-edge infrastructure leading to its headquarters "Technoplex," high-tech research institute "Hankook Technodome," and Asia's largest tire test track "Hankook Technoring."
