Toyota introduced the bZ Time Attack concept – its first electric concept at SEMA – which it claims is a “mobile testbed” for electric racing development. Based on a 2026 bZ with 338 horsepower (0–60 mph in 4.9 seconds) all-wheel drive, the Time Attack features a two-motor powertrain tuned to over 400 horsepower, managed by its own ECU. Toyota didn’t provide official performance estimates, but said the 0–60 mph time could be as low as 4.0 seconds.
From 338 hp AWD bZ to >400 hp test bed
The starting point for the project is a 338-horsepower, all-wheel-drive 2026 bZ. On that platform, Toyota upgraded the 2-motor powertrain to over 400 horsepower, combined with a custom-programmed ECU to optimize response and traction distribution. The goal is to accelerate quickly and ensure durability when operating on the track. As for performance figures, the manufacturer did not release official test parameters.
Track-focused chassis: lowered 6 inches, raised 6 inches
To exploit the tires and aerodynamics, the bZ Time Attack is lowered 6 inches and has a 6-inch longer wheelbase than the stock car. The suspension is completely new with coil-over shocks and Tein springs. The Alcon braking system is equipped with Hawk brake pads – which are adapted from the GR86 Cup and GR Corolla TC race cars – to ensure thermal durability and a consistent brake pedal feel over long distances.
19-inch BBS Unlimited wheels with 305/30 Continental ExtremeContact Sport 02 tires increase contact area, while the suspension setup and wider track serve to serve the body grip and stability when cornering at high speed.
Wide body and performance-oriented aerodynamics
The widebody package focuses on aerodynamic efficiency: black 3D-printed wheel arch covers, a sharp front splitter, a large rear wing and a diffuser extending under the rear bumper. Large air vents on the front wheel arches reduce pressure in the wheel wells, supporting directional stability during deep braking and rapid changes of direction.
Minimalist cockpit, FIA standard
Inside, the bZ Time Attack stripped away as much excess material as possible to reduce weight. The car is equipped with an FIA-standard roll cage, OMP racing seats with OMP seat belts. The rear seats were removed; many decorative details were also cut down, keeping only functional components on the dashboard. The bZ's signature push-button gearshift cluster was relocated to the dashboard for the driver's convenience when racing.
SEMA Scene: From Engine Swaps to Electric Racing
Many of Toyota’s past SEMA projects have focused on engine swaps. This year, the company installed a modern turbocharged V6 in a classic Land Cruiser; before that, a GR86 was swapped with a turbocharged three-cylinder and all-wheel drive from a GR Corolla. Two years ago, Toyota showed off the FJ Bruiser concept, which used a NASCAR V8 on a classic FJ45. With the bZ Time Attack, the company took a different tack: using electric vehicles as a test bed for racing technology.

Summary
The bZ Time Attack isn’t a static show car, but a fully operational prototype, focused on validating the chassis, brakes, aerodynamics, and electric powertrain performance under track conditions. While it’s almost certainly not destined for production, the concept shows that Toyota is actively transferring its expertise from the world of internal combustion engines to an electric platform, with the goal of creating exciting electric cars that are suitable for the motorsports of the future.
