Here's What You Need to Know About the Subaru 'STI E-RA' Electric Hypercar

Back in November, Japan's Subaru stole the spotlight at the 2021 Los Angeles Auto Show with the global debut of its highly anticipated Solterra EV. The 2023 Subaru Solterra is the Japanese automaker's first all-electric offering.

Subaru made another splash last month at the 2022 Tokyo Auto Salon, when its sub-brand Subaru Tecnica International (STI) unveiled the "STI E-RA" motorsports study at the custom car event. 

The electric supercar's "E-RA" moniker stands for "Electric Record Attempt." The automaker aims to lap the legendary Nurburgring race track in a record-setting 6 minutes and 40 seconds.

The record lap time of 6 minutes and 43 seconds was set in June 2021 in a modified Porsche GT2 RS fitted with the Manthey Performance Kit with upgrades to the chassis, brakes and aerodynamics.

The electric STI E-RA will make its record breaking Nurburgring attempt in 2023. If successful, it will also beat the Nio EP9 supercar's time by 6 seconds. 

Subaru is developing the STI E-RA concept under its subsidiary's upcoming motorsport project. The automaker will begin testing the STI E-RA supercar on race tracks across Japan later this year. 

Surprisingly enough, a conservative 60 kWh battery pack is all that powers the STI E-RA electric hypercar. A quad motor all-wheel-drive setup sends power to all four wheels. A Yamaha electric motor on each wheel produces 1,073 HP of maximum power. Each of the high revolution electric motors includes an integrated inverter and gear.

The Subaru STI E-RA also gets "four-wheel torque vectoring" technology. Subaru claims it has designed the torque vectoring system to be driver-focused and prioritize driving pleasure. 

The Subaru STI E-RA is an impressive concept study, and it is already exceeding the expectations of motorsport enthusiasts and governing bodies like the  Fédération Internationale de l'Automobile (FIA). 

The FIA has already announced the new technical regulations and standards for the Electric GT (E-GT) class. All race cars will have strict power and weight limits.

The maximum power output allowed in the E-GT class is limited to 577 HP, and the cars cannot weigh less than 3,150 lbs or more than 3,373 lbs. Safe to say, with its quad motor and 1,073 HP electric powertrain, the STI E-RA exceeds these standards by quite a margin.

Lastly, the Subaru STI E-RA's styling also captures one's attention. In addition to the F1-style air intake, a giant carbon-fiber splitter dominates the front end of the electric racer, and at the rear, we find a massive wing. The design is fitting for an electric super of this caliber.

Subaru also showcased the Solterra STI concept alongside its electric supercar in Japan last month. The Solterra STI is a high-performance version of the company's upcoming battery-powered crossover.
