Tacoma H2 Overlander Concept: 547 HP Fuel Cell Off Roader Explained

Toyota built the Tacoma H2 Overlander Concept for people who want quiet power, long range confidence, and the kind of campsite that makes friends wander over just to ask how it all works. Under the skin is a second generation Toyota Mirai fuel cell stack paired with three hydrogen tanks totaling 6 kg, backed by a 24.9 kWh lithium ion battery. The result is a near silent four wheel drive truck that breathes in oxygen, sips hydrogen, and exhales only water. It is familiar Tacoma toughness on the TNGA F platform, just with a future facing heartbeat.

Power is the part everyone feels first. The concept delivers 547 horsepower from two electric motors, a 225 kW unit up front and a 188 kW eAxle in the rear. Instant torque flows through a front limited slip differential and a rear electronic locking differential, so steep climbs and rutted washboard do not require drama. A TRD billet long travel kit sits over heavy duty Fox 2.5 Performance Elite Series shocks that were adapted from Toyota Tundra development, adding articulation and confidence when the trail gets bony. Braking is upgraded with Tundra front hardware, while custom 17×8.5 wheels wrapped in 35×12.5R17 off road tires put down the grip. A TRD engineered cooling system blends Tacoma TRD Pro and Lexus RZ component know how to keep the hydrogen and electric systems happy under load.

What sets this rig apart is how it supports the whole crew. A 15 kW power takeoff with dual NEMA 14 50 outlets can run a home off grid or charge two battery electric vehicles at once. That means your buddy in a pure EV is not hiking out for help if the trail took longer than planned. One of the cleverest touches is TRD’s patent pending exhaust water recovery system. It captures, filters, and stores the fuel cell’s only byproduct, producing essentially distilled water suitable for washing and showering around camp. It is not meant for drinking, but it is a game changer when water is scarce.

The build story is pure TRD. Teams in California and North Carolina took a gasoline Tacoma and, on a compressed timeline, re engineered it into a hydrogen fuel cell four wheel drive concept. Advanced CAD, 3D printed guides, and a tight multi site loop let them package the stack, tanks, battery, and driveline cleanly within the frame rails. Along the way they created firsts, including the water recovery system and a TRD tailored roboformed tailgate developed with Toyota Motor North America Stamping. The exterior is all function with recycled carbon fiber aero panels, heavy duty bumpers, integrated recovery points, a winch, dual swingouts, tiedowns, a recovery board system, and DOT compliant lighting from lightbars to camp lights.

It is also a statement of strategy. Toyota’s multi pathway approach says there is more than one road to carbon neutrality, and this truck is proof that clean energy and real world capability can be partners. You can see it in person at the 2025 SEMA Show from November 4 to November 7 at the Las Vegas Convention Center in Toyota’s Central Hall Booth 22200.
