Subaru Wants to Break a Nürburgring Record With This 1073-HP Electric Concept Car
Subaru revealed a concept for a new all-electric race car at the Tokyo Auto Salon Friday that it plans to take to the Nürburgring. Called the STI E-RA, it sports a 60 kWh lithium-ion battery powering four electric motors (one for each wheel) with a total output of 1073 hp.
The E-RA in STI E-RA stands for Electric Record Attempt, in case you were wondering. Subaru's goal with the car, as you've probably guessed, is to set fast lap times. Its first mission, according to a statement on the official STI website, is to lap the Nürburgring in 6:40 sometime in 2023.
Because the STI E-RA has four motors, Subaru has employed a new torque vectoring system meant to balance the limit of grip between wheels and stabilize the car through corners. Torque is independently applied to each wheel depending on load shifts using sensors for wheel speed, steering angle, g-force, yaw rate, brake pressure, and wheel load. In other words, some seriously high-tech stuff.
Subaru hasn't said whether it plans to eventually enter a version of the STI E-RA into any official racing series, but does mention it used a specific method of motor-to-wheel attachment that is included in the FIA's future E-GT regulations. So there remains a small possibility this car could evolve into something we'd see racing against other makes in an all-electric series.
