The Toyota bZ Time Attack Concept is a battery-electric prototype vehicle built for the 2025 SEMA Show, created to explore the limits of Toyota’s BEV architecture in a motorsports environment.
The concept explores Toyota’s intent to study how future battery-electric models can serve track use while advancing its broader BEV research program.
We recently had a chance to check out the Toyota bZ Time Attack Concept in person, and here are our observations.
Design
The bZ Time Attack is based on the 2026 Toyota bZ AWD platform. The exterior features a tri-color finish in pearl white, metallic black, and red. The panels incorporate a full wide-body system engineered through laser scanning, CAD development, and 3D printing.
At the front, black highlight panels on the hood, along with the extremely low lip splitter, give the concept a unique look. Wide-body fender arches and a massive wing define the profile, and the body sits six inches lower than the stock bZ, with a six-inch increase in track width. Black side skirts and a large rear diffuser are designed to improve downforce.
Interior
The interior of the bZ Time Attack Concept removes all production equipment and uses motorsport components in their place. OMP HTE-R racing seats and OMP harnesses replace the factory seating, and the cabin layout focuses on packaging and weight reduction for track use.
Rear seats and all trim panels are removed to cut mass. An FIA-spec roll cage is integrated into the body and connects the A, B, and rear pillars to manage loads during hill climb and time attack competitions.
Observing the concept more closely, we noticed exposed door structures with no trim panels, revealing the inner latch mechanism and wiring. The steering column has no plastic shrouds and exposes the adjustment mechanism and wiring.
Padding is fitted to the cage around the front seating area. The painted metal floor has no insulation or carpeting. Cross-bracing behind the seats replaces the cargo area.
The OMP seats are mounted low to lower the hip point and shift weight more toward the center of the car. Window glass remains, but grab handles, airbags, interior plastics, trims, and screens are removed.
Specifications
The production-spec bZ AWD system delivers 338 hp, but the concept exceeds this output, producing more than 400 hp using Toyota R&D-tuned electric motors, with power delivered to all four wheels through the platform’s AWD layout.
The car is engineered for short-duration competition use, prioritizing power delivery and thermal stability over long-distance capability. This is within the limits of what battery technology can offer today. The vehicle uses a bespoke ECU calibration to manage torque distribution for track conditions.
TEIN coilovers and springs manage ride height and damping. The braking system uses Alcon components with Hawk pads adapted from Toyota’s 86 Cup and Corolla TC programs. Mechanical grip comes from 305/30ZR19 XL Continental ExtremeContact Sport 02 tires mounted on 19×11-inch BBS Unlimited wheels.
Price & Release Date
Being a one-off show car, the bZ Time Attack Concept is not expected to go into production. However, Toyota’s R&D team is expected to learn about vehicle dynamics, thermal management, the limits of the bZ’s AWD system, and the modularity offered by 3D printing. These can then be applied to motorsports and high-performance BEV vehicles in the future.
