Toyota Debuts All-Electric “bZ Time Attack” AWD Concept at 2025 SEMA Show

LAS VEGAS (Oct. 31, 2025)- Pushing the limits of electric vehicle performance, Toyota will debut its first-ever battery-electric SEMA concept build with the bZ Time Attack Concept at the 2025 SEMA Show-a purpose-built, BEV machine engineered to take on both time attack circuits and hill climbs.

Designed to explore the performance potential of Toyota's BEV technology, this vehicle showcases competition aerodynamics, motorsports-grade suspension and engineering, and a significant increase in all-electric horsepower over stock.

The concept begins with a strong foundation: the 26MY AWD bZ, which already delivers 338 horsepower and a 0-60 mph time of just 4.9 seconds in showroom form. Looking ahead, Toyota is also expanding its all-electric lineup with an all-new bZ model arriving for the 2026 model year, bringing improved range, power, and charging capabilities. In addition, Toyota will introduce two all-new BEVs in 2026-the bZ Woodland and the C-HR-further broadening customer choice and underscoring the company's commitment to electrified performance and innovation.

"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."

Schwerter and his Toyota Motorsports Garage team have collaborated on standout Toyota SEMA builds for more than two decades. Still, the bZ Time Attack Concept presented several unique challenges, from balancing battery performance with weight distribution to designing an aggressive widebody and aero package suited for motorsports. Unlike conventional builds, the team had to rethink how aerodynamics and fitment could be achieved on an EV platform, while helping to provide safety and durability under extreme conditions.

"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."

Packaging a widebody and full aero suite onto an EV chassis presented challenges not found in conventional builds, driving the team to rethink everything from airflow management to cooling strategies.

The solution came through a hybridized approach to fabrication. Toyota R&D, TRD, and a network of advanced suppliers combined laser scanning, CAD development, and large-scale 3D printing to bring the design to life. Fender arches were digitally modeled, printed at full scale, then hand-finished for strength and precision. Key to this process was Toyota's Add Lab in Georgetown, Kentucky- led by Sr. Engineering Manager Greg Stewart and Additive Manufacturing Engineer Dallas Martin- whose rapid prototyping capabilities gave R&D the flexibility to hit tight deadlines. This method drastically cut prototyping time, allowing for rapid iterations of the one-off widebody and aero system.

The result: a car lowered a whopping six inches from stock ride height, with massive six-inch track increase and a fully integrated aero package including rear wing, side skirts, front splitter, and rear diffuser.

Under the skin, the bZ Time Attack Concept starts with a 2026 Toyota bZ AWD platform. Power delivery to all four wheels comes from Toyota R&D-tuned electric motors delivering over 300 kW (400+ hp), managed through bespoke ECU calibration. TEIN coilovers and springs suspend the chassis, while drastically improved braking performance comes by way of an Alcon system with Hawk pads adapted from Toyota's 86 Cup and Corolla TC race programs. A full FIA-spec 4130 chromoly cage stiffens the chassis, while the interior is fitted with OMP HTE-R racing seats and OMP harnesses. The chassis rolls on 19×11-inch BBS Unlimited wheels shod with huge 305/30ZR19 XL Continental Extreme Contact Sport 02 tires, adding substantial mechanical grip to go along with the impressive aerodynamic downforce.

Every aspect of the build reflects Toyota's willingness to experiment with nontraditional fabrication methods. The bodywork, finished in a custom PPG pearl/metallic white, metallic black, and red tri-color scheme, demonstrates what happens when additive manufacturing and traditional race-car craftsmanship intersect. From CAD modeling at Dark Matter Laser Works to the 3D-printed components produced by Toyota's Add Lab, the project embodies a new way of thinking about concept-to-competition builds. For Toyota, the bZ Time Attack Concept isn't just a concept car-it's a rolling test bed for the next generation of EV motorsport development.

"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."

The bZ Time Attack Concept will be on display at the 2025 SEMA Show from November 4-7 at the Las Vegas Convention Center in the Toyota booth (Central Hall, Booth 22200). The concept is just one of over two dozen displays in support of this year's display theme: Powered by Possibility, where Toyota celebrates innovation with a build for every powertrain, including gasoline internal combustion (ICE), BEV, hybrid (HEV), plug-in hybrid (PHEV) and Fuel Cell Electric (FCEV). Attendees are invited to visit Toyota's booth to experience this innovative concept build up close and discover how Toyota continues to imagine what could come next.
