Mercedes-Benz is putting the finishing touches on its eArocs 400, an all-electric truck designed for urban construction transport, with deliveries slated to start in the fourth quarter of 2026. The vehicle, which will be available for order starting in April 2026, recently underwent rigorous winter testing in the Arctic Circle at temperatures as low as -20°C to ensure reliable performance in extreme conditions.
The eArocs 400 is designed with urban work sites in mind, offering the benefits of quiet operation and zero emissions. Before launch, Mercedes-Benz engineers focused on validating the truck’s functionality across a range of challenging climates.
Mercedes-Benz Completes Development of its Electric Urban Truck
Winter testing prioritized traction and driving stability on icy and snowy roads. Simultaneously, engineers evaluated battery performance in freezing temperatures, verified cold-start capabilities, tested high-power battery recharging, assessed electrical motor efficiency, and confirmed the functionality of the energy recovery system during operation.
“The winter tests in Finland subjected the eArocs 400 to demanding tests under dry and extremely cold conditions, which it passed safely. With stable driving characteristics and an autonomy and charging profile within expected parameters, it clearly demonstrated its capability,” said Michael Kimmich, Head of Development for the Mercedes eArocs 400.
The extreme-condition testing not only refined the eArocs 400 but similarly provided valuable insights for improving parameters in future electric truck models. This commitment to electric vehicle development reflects the broader industry trend toward sustainable transportation solutions.
Production of the eArocs 400 will commence in the third quarter of 2026 at Mercedes-Benz’s Wörth am Rhein plant, located west of Stuttgart, Germany. The integration of the body and the electric mechanical system will be handled by Paul Group, based in Vilshofen an der Donau, Germany.
Weighing Up to 44 Tons and Achieving 240 km of Range
The Mercedes eArocs 400 is designed for construction tasks and will be offered with an 8×4/4 axle configuration and four different wheelbase options. It will be available as a dump truck or a concrete mixer, with weights of 37 or 44 tons, respectively, covering the majority of essential applications for urban construction sites.
The truck will utilize Lithium Iron Phosphate (LFP) batteries, chosen for their durability and high net capacity. The batteries, with a volume of 414 kWh, will be located behind the cab.
Mercedes-Benz claims the eArocs 400 will achieve a 50% improvement in energy efficiency compared to a diesel equivalent. The dump truck version will have an electric range of 240 km, while the concrete mixer version will reach 200 km. The truck can be recharged at a rate of 400 kW, allowing a charge from 10% to 80% capacity in just 46 minutes.
