The Toyota Tacoma H2-Overlander Concept reimagines overlanding with a hydrogen fuel cell and battery-electric hybrid powertrain delivering 547 horsepower, zero emissions, and advanced off-grid functionality.
Highlights
- Hydrogen Fuel Cell + Battery Electric: Combines a Mirai-derived fuel cell stack and 24.9-kWh battery for efficient, quiet propulsion.
- Off-Grid Power: 15-kW output enables charging two EVs or powering a home through dual NEMA 14-50 outlets.
- Patent-Pending Water Recovery System: Captures and filters tailpipe water emissions for outdoor use.
- Engineered by TRD-USA: Developed by Toyota Racing Development teams in California and North Carolina for SEMA 2025.
Hydrogen and Battery Powertrain Integration
The Tacoma H2-Overlander Concept showcases Toyota’s multi-pathway approach to carbon neutrality, integrating hydrogen fuel cell and battery technologies on the proven TNGA-F truck platform. The system employs a second-generation Mirai fuel cell stack and three hydrogen tanks (6 kg total capacity) combined with a 24.9-kWh lithium-ion battery pack. Together, they drive a 225-kW front motor and 188-kW rear eAxle, producing 547 horsepower and near-instantaneous torque.
A TRD-engineered cooling system, adapted from the Tacoma TRD Pro and Lexus RZ, ensures thermal stability during demanding overland conditions. Power delivery routes through front and rear differentials, enabling true 4WD capability for rugged terrains.
Overlanding Engineering and Performance
To match its powertrain innovation, the concept integrates TRD billet long-travel suspension and Fox 2.5 Performance Elite shocks, adapted from the Tundra’s development program. Custom 17×8.5-inch wheels with 35×12.5R17 off-road tires, reinforced braking from the Tundra, and chassis upgrades provide exceptional control off-road.
Sustainable Utility and Design Innovation
Among its most distinctive technologies is TRD’s patent-pending exhaust water recovery system, which filters water vapor from the hydrogen fuel cell into usable, distilled water—ideal for washing or showering in remote environments.
The H2-Overlander’s body features recycled carbon-fiber aero panels, a custom overlanding camper, and integrated off-road bumpers with recovery points, winch, and storage systems. TRD’s collaboration across its U.S. engineering hubs utilized CAD modeling and 3D-printed guides to convert a gasoline Tacoma into a hydrogen-powered prototype in record time.
Powered by Possibility at SEMA 2025
Unveiled under Toyota’s “Powered by Possibility” theme, the Tacoma H2-Overlander Concept demonstrates how hydrogen can deliver both adventure and sustainability. According to Mike Tripp, Toyota Marketing Group VP, the concept “proves that clean energy and real-world capability can go hand in hand.”
The Tacoma H2-Overlander Concept will be on display at the 2025 SEMA Show (Nov. 4–7) in the Toyota booth (Central Hall, Booth 22200), alongside other builds spanning ICE, HEV, PHEV, BEV, and FCEV technologies.
