Mercedes is winter testing the brand-new eArocs 400 ahead of series production
According to the truck maker, "tests focused on traction and driving stability on snow and ice covered roads, cold start performance, battery and charging behavior at extreme subzero temperatures". The eArocs 400, officially launched at bauma, last year, will go on sale at the beginning of April this year.
The new battery electric Mercedes-Benz eArocs 400 designed for urban construction transport has successfully completed intensive winter testing under extreme conditions, namely at temperatures reaching –20 °C. Those tests were carried out on snow and ice near the Arctic Circle earlier this year. The new Mercedes eArocs 400 was officially launched at bauma 2025, as the truck is designed for the construction sector.
According to the truck maker, “tests focused on traction and driving stability on snow and ice covered roads, cold start performance, battery and charging behavior at extreme subzero temperatures, as well as the efficiency of the electric powertrain and recuperation performance during winter operation”.
Mercedes eArocs 400 awaited next April
The eArocs 400 will go on sale at the beginning of April this year. The base vehicle will be produced at the Mercedes-Benz plant in Wörth am Rhein starting in the third quarter of 2026. Final integration of the electric powertrain will then be carried out by the Paul Group based in Vilshofen an der Donau (Germany). The vehicle will initially be available as a 37-ton and 44-ton variant in the 8×4/4 axle configuration and in four different wheelbases. It can be built as a concrete mixer or construction tipper, thus covers essential applications for street-oriented construction transport.
For the new eArocs 400, Mercedes-Benz Trucks is adopting essential components from the eActros portfolio. In addition to the front box and the power take-off (PTO), this also includes batteries based on lithium iron phosphate cell technology (LFP). These batteries feature in particular a long durability and a particularly high usable battery capacity.
“The winter tests in Finland subjected the eArocs 400 to demanding trials under dry, extremely cold conditions — trials it handled with confidence. With stable driving characteristics and a range and charging profile within the expected parameters, it clearly demonstrated its capability”, commented Michael Kimmich, Head of Development eArocs 400.
