Subaru reveals Nurburgring-bound EV racer, which will help develop road-going 4WD EVs.
Subaru’s radical new STI E-RA concept previews an all-electric track car which will be used to develop and showcase the company’s all-wheel-drive EV capabilities.
Revealed at the Tokyo Auto Salon, the track-bound concept forms part of the STI E-RA Challenge Project, which Subaru has initiated with the aim of “gaining experience and training of new technologies in the world of motorsports in this carbon-neutral era focused on combating global warming”.
Like the brand’s debut production EV, the Solterra, the STI E-RA is claimed to draw on Subaru’s strength in “all-wheel control legacy”, which it established over two decades competing in global rally championships with the Legacy and Impreza.
The concept aims to promote what Subaru says are its cars’ defining traits, namely the “pleasure of driving” and an “absolute sense of security” on the road.
It uses a total of four motors – one on each wheel – and has a combined output of 800kW, exactly matching the similarly conceived Mission R concept Porsche revealed last year.
The output of each of the “high-torque” motors, supplied by Yamaha, can be altered instantly as required, courtesy of an advanced torque vectoring system tuned specifically with a focus on driving pleasure.
Subaru chose to mount a motor on each wheel to allow for optimal power delivery and improved yaw control, but also because such a set-up is permitted by the FIA’s regulations for the new E-GT race series which will get underway in 2023 – suggesting a Subaru entry is on the cards.
Subaru says it will compete in motorsports as part of a drive to improve the driving characteristics of its road cars and to prepare for a “future electrified society”.
Following an on-track development programme over the course of 2022, Subaru will take the STI E-RA to the Nurbürgring, where it will attempt to achieve a 6mins 40secs lap time.
