Toyota Tacoma H2-Overlander Concept Revealed at SEMA 2025 — 547 HP Hydrogen Power and Water Recovery Innovation

At SEMA 2025 in Las Vegas, Toyota unveils the Tacoma H2-Overlander Concept — a hydrogen fuel-cell and battery electric pickup with 547 hp, 15 kW power output and a unique TRD Water Recovery System for off-grid living.

Toyota unveiled the Tacoma H2-Overlander Concept at the 2025 SEMA Show in Las Vegas, presenting an experiment in combining hydrogen fuel cell technology with electric drive for power, range, and zero emissions.

The project was engineered by Toyota Racing Development teams in California and North Carolina, with support from Toyota Motor North America R&D. Built on the TNGA-F platform, it integrates a second-generation Mirai fuel cell stack and three hydrogen tanks totaling 6 kg, paired with a 24.9 kWh lithium-ion battery. Together they feed a 225 kW front motor and a 188 kW rear eAxle, producing a combined 547 horsepower.

The H2-Overlander features full-time four-wheel drive with electronically controlled differentials and a TRD Long-Travel suspension using Fox 2.5 Performance Elite shocks adapted from the Tundra. It also gains larger Tundra brakes and 35-inch off-road tires for extra capability.

Among its most distinctive innovations is the TRD Water Recovery System, which captures and filters water generated by the fuel cell’s chemical reaction. The purified water can be used for washing or showering—an invaluable feature for extended off-grid expeditions.

The truck can also supply up to 15 kW through NEMA 14-50 outlets—enough to power a camp, a small home, or even charge two EVs at once. In this way, it serves as both a sustainable vehicle and a mobile energy hub.

Developed on a tight timeline, the concept relied heavily on digital modeling and 3D-printing. TRD engineers created several patent-pending systems, including the water recovery unit and a specially formed tailgate built in collaboration with Toyota’s stamping division.

The Tacoma H2-Overlander fits within Toyota’s multi-pathway vision for a carbon-neutral future—where hydrogen stands alongside hybrids, BEVs, and plug-in systems. The company already tests fuel-cell trucks and the Hilux FCEV prototype in Europe, reinforcing its commitment to diverse clean technologies.

Seen in that context, the H2-Overlander is a rolling laboratory—a bold showcase of how Mirai technology can leave the pavement behind and how hydrogen might power the next generation of overland adventures.
