Tacoma H2-Overlander Concept demonstrates hydrogen off-road capability

Toyota has revealed the Tacoma H2-Overlander Concept, a hydrogen fuel cell electric vehicle (FCEV) designed to demonstrate the off-road potential of alternative powertrains. The concept truck combines hydrogen fuel cell and battery-electric technologies on the TNGA-F platform, producing water as its only tailpipe emission.

Developed by Toyota Racing Development (TRD) engineering teams in California and North Carolina, with support from Toyota Motor North America Research and Development, the H2-Overlander was built for the 2025 SEMA Show in Las Vegas. It uses a second-generation Toyota Mirai fuel cell stack and three hydrogen tanks with a total capacity of six kilograms. The system powers a 225-kilowatt front motor and a 188-kilowatt rear eAxle, supplemented by a 24.9-kilowatt-hour lithium-ion battery pack. Combined output is rated at 547 horsepower.

The concept features a front limited-slip differential and rear electronic locking differential for four-wheel-drive capability. Suspension components include a TRD billet long-travel kit and Fox 2.5 Performance Elite Series shocks adapted from the Toyota Tundra, along with upgraded Tundra front brakes and 17-inch wheels fitted with 35-inch off-road tires. A TRD cooling system derived from Tacoma TRD Pro and Lexus RZ components helps maintain temperature stability for both hydrogen and electric systems.

A notable feature of the concept is a patent-pending TRD exhaust water recovery system that captures and filters the water produced as a byproduct of the hydrogen fuel cell. The recovered water, which is essentially distilled, can be used for washing or showering but is not intended for drinking. The truck also includes a 15-kilowatt power takeoff system with dual NEMA 14-50 outlets capable of charging two electric vehicles simultaneously or powering external equipment.

TRD engineers used advanced computer-aided design, 3D-printed guides, and cross-facility collaboration to complete the concept within a limited timeframe. The project also introduced a TRD-specific, roboformed tailgate developed with Toyota Motor North America Stamping. The exterior incorporates recycled carbon-fiber panels, overlanding accessories, and off-road components such as heavy-duty bumpers, recovery points, a winch, dual swingouts, and integrated lighting.

Toyota officials said the H2-Overlander Concept illustrates the company’s multi-pathway strategy toward carbon neutrality, which includes internal combustion, hybrid, plug-in hybrid, battery electric, and hydrogen fuel cell technologies. The truck will be displayed at the 2025 SEMA Show from November 4–7 at the Las Vegas Convention Center in Toyota’s Central Hall booth.
