The Mercedes NextGen2 2026 truck with a range of 1,000km

There is a quiet shift happening in long haul trucking, and it is not being led by louder engines or bigger exhaust stacks. It is being shaped by hydrogen, real world testing, and technology that is finally close to daily operation. The Mercedes-Benz NextGenH2 Truck represents a major step forward, not as a concept, but as a truck that is almost ready to work.

This new fuel cell truck builds on years of testing with the first generation GenH2 prototypes, keeping what worked while refining what drivers and fleets actually need. Liquid hydrogen sits at the center of the story, allowing ranges well beyond 1,000 kilometers on a single fill even at full load. That range matters, because it places hydrogen trucks into the same operational reality as diesel, without changing how long drivers spend refueling.

Under the cab, the twin fuel cell system converts hydrogen into electricity, working alongside a buffer battery to power the electric axle. The result is instant torque, smooth acceleration, and quiet operation, even when hauling heavy loads through steep terrain. In real customer trials, hydrogen consumption landed between 5.6 and 8 kilograms per 100 kilometers, depending on weight and route, showing that this technology is no longer theoretical.

A major leap comes from using proven series components already found in production trucks. The integrated electric axle, advanced driver assistance systems, and the ProCabin design improve efficiency, safety, and comfort all at once. Aerodynamic gains alone reduce drag by 9 percent compared to earlier designs, directly improving range and energy use.

Inside, drivers get a modern digital cockpit, low noise levels, and two full sleeping beds, now approved for overnight stays thanks to new hydrogen safety monitoring systems. Behind the cab, a more compact technical layout shortens the wheelbase to 4,000 millimeters, improving trailer compatibility and everyday usability.

What makes this truck stand out is not just hydrogen, but readiness. Daimler Truck plans to build 100 units in a small production run, with customer deployments starting at the end of 2026. With government support and extensive real world testing already completed, this is a serious move toward zero emission long haul transport. 

Liquid Hydrogen Enables Ranges Well Over 1,000 Kilometers...In the development of hydrogen-based drives, Daimler Truck prefers the use of liquid hydrogen. At -253 degrees Celsius, liquid hydrogen has a significantly higher energy density compared to gaseous hydrogen, allowing more hydrogen to be stored, substantially increasing range and delivering performance comparable to conventional diesel trucks. The capacity of the two liquid hydrogen tanks has been increased compared to the first generation of the Mercedes-Benz GenH2 Truck, so that a total of up to 85 kg of hydrogen can now be filled. Refueling is possible from both sides as both tanks are connected. Using the sLH2 refueling standard developed by Daimler Truck and Linde, the truck can be filled with liquid hydrogen within 10–15 minutes — as safe, fast, and simple as refueling today’s diesel trucks.

Transporting liquid hydrogen requires less logistical effort, and liquid hydrogen tanks offer cost and weight advantages over gaseous high-pressure tanks. These benefits enable higher payloads, making deployments comparable with today’s diesel trucks. Daimler Truck successfully demonstrated this at the end of 2023 during the #HydrogenRecordRun, when a Mercedes-Benz GenH2 Truck with a gross combined vehicle weight of around 40 tonnes covered 1,047 km on a single filling of liquid hydrogen.
