With high-speed straights, technically demanding sections, different surfaces, and big bumps, the street circuit in São Paulo, a metropolis with a population of 12 million, posed quite a challenge for the 22 Formula E drivers. Roughly two thirds of the track had been resurfaced with asphalt, especially for the Brazilian round of the world championship, while other parts were concrete. Hankook Formula E race engineer Jiwoong Choi: “The Hankook iON Race mastered the challenges of this circuit without any problems. It supported the drivers on all four different surfaces with a high level of grip. Despite the very high air and track temperatures, the Hankook iON Race was still consistent and delivered its usual strong performance.”
