Carbon neutral motorsport? Subaru studies it with the E-RA STI – acronym for “Electric Record Attempt” -, a battery-powered racing car developed by the sports division of the Japanese manufacturer with the aim of gaining experience in the field of electron-powered supercars.
The vehicle is driven by four electric motors and an integrated inverter, supplied by Yamaha: everything is powered by a 60 kWh lithium-ion battery, while the maximum power output is 1,088 hp. The drive torque, on the other hand, is distributed to the four drive wheels by means of a sophisticated torque vectoring device, based on parameters such as tire grip, speed, steering angle, lateral angle, yaw angle, etc. .
The aerodynamics are also very sophisticated, designed to crush the vehicle to the ground. Target? Lap on the old Nurburring circuit in 6 minutes and 40 seconds. A first that Subaru will try to make its own in 2023. The brand has also developed its first aesthetic kit for the Solterra, the company’s first 100% electric vehicle, jointly engineered with Toyota: the accessories branded STI, Subaru’s sports division, include a new roof spoiler, red moldings on the front splitter, side skirts and rear diffuser.
