At the 2025 SEMA Show, Toyota Uses bZ Time Attack Concept to explore how far battery-electric vehicles can be pushed in competitive motorsport. Rather than a design showcase, this aggressive prototype serves as a rolling laboratory, helping engineers understand how modern EV platforms perform under extreme racing conditions like time attack and hill climb events.
An Engineering Study, Not a Show Car
Toyota is clear about the intent behind this concept. Built by the Toyota Motorsports Technical Center, the bZ Time Attack is not meant for direct competition or production. Instead, Toyota Uses bZ Time Attack Concept as an engineering study to analyze sustained power delivery, thermal control, chassis rigidity, and aerodynamic efficiency—key challenges when replacing combustion engines with batteries and electric motors.
High-Output Powertrain on a Proven Platform
The concept is based on the upcoming 2026 Toyota bZ all-wheel-drive platform. While the production model produces 338 horsepower and reaches 60 mph in under five seconds, engineers recalibrated the dual-motor system for racing duty. The result is over 300 kW (more than 400 horsepower), optimized for short, high-intensity performance rather than everyday efficiency.
Motorsport-Focused Chassis and Handling
Unlike road-going EVs, the Time Attack Concept is built around pure motorsport constraints. Ride height is lowered by roughly six inches, and the track width is expanded by the same amount for added stability. A full FIA-spec 4130 chromoly roll cage reinforces the chassis, while TEIN coilovers and an Alcon braking system with Hawk pads—sourced from Toyota’s 86 Cup and Corolla TC programs—handle suspension and stopping duties.
Advanced Aerodynamics Through Rapid Prototyping
Aerodynamics posed a major challenge due to the cooling needs of EV components. Toyota Uses bZ Time Attack Concept to refine airflow management using laser scanning, CAD design, and large-scale 3D printing. The widebody kit, front splitter, side skirts, rear diffuser, and massive rear wing were digitally designed and hand-finished to balance downforce, cooling, and drag.
Stripped-Out Interior for Safety and Weight Savings
Inside, the cabin is fully stripped to reduce mass. It features OMP HTE-R racing seats, competition harnesses, exposed mechanical structures, and racing controls. Toyota Uses bZ Time Attack Concept to collect valuable real-world data, shaping future high-performance EV development and redefining what electric racing platforms can achieve.
