New 1073 HP STI E-RA - Subaru’s High-Performance EV Future Is Revealed
What do Subaru's performance cars look like in the future? We now get a good idea of what Subaru has planned for its all-wheel-drive high-performance models.
Subaru Corporation and Subaru Tecnica International unveiled its STI E-RA (Electric-Record Attempt) concept performance car with 1073 horsepower at the Tokyo Auto Salon today. Subaru's all-electric high-performance future starts today.
Subaru enters the high-performance electric era
It's an exciting future that will start with eco-performance, a "near-future" challenge project developed to gain experience and training of new technologies in the world of motorsports in this carbon-neutral era focused on combating global warming," Subaru announced today.
Subaru's all-wheel-drive technology will evolve in the new carbon-neutral era by testing its 1073 horsepower eco-performance STI E-RA high-performance sports car on the Nurburgring.
Subaru says, "The first goal of this model is to try to record a lap time of 400 seconds (6 minutes 40 seconds) in a time attack at the Nurburgring circuit from 2023 onward." Subaru will also use the all-electric performance car in other driving experiments, including circuits in Japan, starting in 2022.
The current all-electric model lap record at the Nurburgring was set by Tesla in a Model S Plaid EV with a time of 7:35.579. It's nothing new for Subaru to attempt records with the STI. They have been doing it for decades. Check out our report here.
Subaru's four-motor all-wheel-drive
Subaru says they will develop its "all-wheel control system" with a newly adopted proprietary 4-motor 4-wheel torque vectoring technology. The high-torque high-revolution type motors use an integrated inverter and a gear for hyper EVs and were developed and supplied by Yamaha Motor Co. These motors are driven by a lithium-ion battery with a 60kWh storage capacity.
Subaru will send power from the high-torque high-revolution electric motors to all four wheels that equalize the balance to the grip limit of each of the four wheels with a driver-focused control system. Subaru says "the all-wheel-drive system "raises the grip level to the maximum and stabilizes car body position."
The all-wheel-drive system calculates the signals from sensors in wheel speed, vehicle speed, steering angle, G-force, yaw rate, brake pressure, "and wheel load, determines the drive/braking torque of each wheel to gain a target stability factor, and provides instructions to the inverter," Subaru said in the press release today.
An all-electric future includes the WRX STI
Subaru and Subaru Tecnica International will use the eco-performance STI E-RA 1073 horsepower high-performance sports car to develop its electric all-wheel-drive technology in its WRX STI performance sports car.
Subaru says, "We will utilize the insight gained from this project as an initiative for a future electrified society. STI will continue to create new values so that cars will remain enjoyable, and which enrich the lives of our customers in an increasingly decarbonized world, for all Subarus."
Subaru will also develop the new all-wheel-drive eco-performance technology in its next-generation Subaru Forester, Outback, Crosstrek, Ascent SUVs, and other production models. Subaru's high-performance electric future starts now.
