Toyota Uses bZ Time Attack Concept to Probe the Limits of EV Racing - CleanTechnica

At the 2025 SEMA Show, Toyota unveiled the bZ Time Attack Concept, a battery-electric vehicle (BEV) prototype designed to explore the limits of electric motorsport performance rather than serve as a styling exercise or competition entry. Built on the forthcoming 2026 all-wheel-drive bZ platform, the concept delivers over 400 horsepower through recalibrated dual motors, emphasizing short-duration power output for racing conditions like time attack and hill climbs. The vehicle features significant modifications from production EVs, including a lowered ride height by six inches, a widened track, a reinforced chassis with an FIA-spec roll cage, and adapted suspension and braking components from Toyota’s circuit racing programs. A key focus of the project was addressing the complex aerodynamic and thermal management challenges unique to EVs, balancing cooling requirements for batteries and motors with drag reduction. Toyota employed advanced techniques such as laser scanning, CAD modeling, and large-scale 3D printing to develop a bespoke widebody aero package, including fender extensions
