Subaru STI E-RA Concept Unveiled!
Subaru STI E-RA Concept Overview
At the Tokyo Auto Salon on Friday, Subaru unveiled a concept electric-race car that STI will employ to break the Nürburgring lap record.
It introduced two electric concept cars to the Tokyo Auto Salon in 2022, both of which are the work of Subaru Tecnica International, the Japanese brand’s motorsport affiliate.
In contrast, the Solterra STI concept depicts a high-performance version of the Company’s electric crossover.
Here are the three Major Highlights:
- The Solterra STI concept adds a rear wing and a red-accented front splitter to a hypothetical sportier form of Subaru’s electric crossover.
- At the Tokyo Auto Salon in 2022, The Company debuted the STI E-RA concept. It has a 1073-horsepower engine and torque-vectoring all-wheel-drive system.
- A WRX and a BRZ with STI performance equipment, like a carbon-fiber rear wing, were also displayed.
Subaru’s latest electric crossover, the Solterra STI concept, has been given a performance makeover.
The STI idea includes a roof-mounted spoiler and a red front splitter. The side skirts, rear bumper, and one spoke of the five-spoke wheels all have red highlights.
Given that Toyota also unveiled a performance version of the Solterra’s sibling car, the Toyota bZ4X, production versions of both vehicles are a distinct possibility.
Subaru hasn’t revealed detailed technical information on the Solterra STI.
Battery Power & Performance
The STI E-RA is equipped with a 60 kWh lithium-ion battery that powers 4 electric motors with a joined output of 1073 horsepower i;e, one for each wheel.
If you were wondering, the E-RA in STI E-RA refers to the Electric Record Attempt.
In addition, the E-RA can now have torque-vectoring all-wheel drive and a 60.0-kWh lithium-ion battery to power the motors.
The all-wheel-drive system was developed to comply with the FIA’s E-GT motorsport regulations, which will serve as the foundation for an electric sports car racing series in 2023.
Subaru’s goal with the car is to set fast lap times. According to the official STI website statement, the STI E-RA’s first aim is to circuit Germany’s Nürburgring in 6:40 in 2023.
Because the STI E-RA has four motors, the Company used an impressive torque vectoring technology to balance the limits of grip across the wheels and stable the vehicle through turns.
Sensors for wheel speed, steering angle, g-force, yaw rate, braking pressure, and wheel load apply torque to each wheel independently based on load shifts.
To put it another way, this is some very high-tech stuff.
The Company hasn’t announced whether it expects to race a version of the STI E-RA, but it used a specific form of motor-to-wheel attachment included in the FIA’s future E-GT regulations.
So there’s still a chance this car may mature into something we’d see competing in an all-electric series against other manufacturers.
