Toyota's bZ Time Attack concept uses large-scale 3D printing to create aerodynamic components, showcasing rapid prototyping for electric motorsports.
Japanese automotive giant Toyota has unveiled its first battery-electric SEMA concept, the bZ Time Attack Concept, at the Las Vegas Convention Center, Booth 22200. Key components—including full-scale fender arches and aerodynamic elements—were digitally modeled, 3D printed, and hand-finished, showcasing how additive manufacturing (AM) enables rapid prototyping, precise fabrication, and flexible design for high-performance motorsports applications.
“This year at SEMA, we wanted to push ourselves into unexplored territory,” said Marty Schwerter, lead builder and director of operations at Toyota’s Motorsports Technical Center. “It’s a chance to explore, learn, and create something that shows just how much potential exists within Toyota’s BEV platforms.”
Additive Manufacturing and Engineering Approach
The concept is based on the 26MY AWD bZ, which delivers 338 horsepower and accelerates from 0–60 mph in 4.9 seconds in stock form. The Toyota Motorsports Garage team faced unique challenges, as balancing battery performance with weight distribution and integrating a widebody and full aero package on an EV platform required rethinking conventional approaches to aerodynamics, fitment, and structural durability.

“The goal wasn’t to simply create a showpiece—It was to see how far the new bZ platform could be pushed in a motorsport setting,” said Schwerter. “And that meant that we had to tackle the two biggest hurdles for any electric competition car: battery performance and aerodynamic integration.”
To overcome these challenges, Toyota R&D, TRD, and advanced suppliers combined laser scanning, CAD development, and large-scale 3D printing. Full-scale fender arches were digitally modeled, 3D printed, and hand-finished for strength and precision. Toyota’s Add Lab in Georgetown, Kentucky, led by Sr. Engineering Manager Greg Stewart and Additive Manufacturing Engineer Dallas Martin, enabled rapid prototyping, allowing multiple iterations of the custom widebody and aero system within tight deadlines. The final package lowered the ride height by six inches, widened the track by six inches, and incorporated a fully integrated rear wing, side skirts, front splitter, and diffuser.
Performance and Technical Details
The bZ Time Attack Concept rides on the 2026 Toyota bZ AWD platform, with over 300 kW (400+ hp) delivered to all four wheels via R&D-tuned electric motors and a custom ECU. TEIN coilovers and springs manage the chassis, while an Alcon braking system with Hawk pads from Toyota’s 86 Cup and Corolla TC programs ensures improved stopping power. The car also features a full FIA-spec 4130 chromoly cage, OMP HTE-R racing seats, and harnesses. It rolls on 19×11-inch BBS Unlimited wheels with 305/30ZR19 XL Continental tires, combining mechanical grip with aerodynamic downforce.

“Every SEMA build challenges Toyota’s engineering and design teams to outdo themselves from the year before,” said Mike Tripp, group vice president, Toyota Marketing. “With the bZ Time Attack Concept, the challenge was greater than ever: transforming an all-electric Toyota vehicle into motorsport reality. The bZ Time Attack Concept is not only a striking visual concept but also a serious performance contender.”
