Developed under STI’s near-future motorsport study project, the STI E-RA Challenge Project, launched with the aim of gathering experience with new technologies in the world of motorsports for the carbon-neutral era.
For the motors, a high-torque high-revolution type with an integrated inverter and a gear for hyper EVs, which were developed and supplied by Yamaha Motor Co., Ltd. have been adopted. This motor is driven by a lithium-ion battery with a storage capacity of 60kWh and the unique torque vectoring AWD (All Wheel Drive) system technology. Its output is 800kW (1088ps) and maximum torque is 1100Nm.
The first goal of this model is to try to record a lap time of 400 seconds (6 minutes 40seconds) in a time attack at the Nürburgring Nordschleife from 2023 onward, after repeating driving experiments including at circuits in Japan in 2022.
