Electric Mercedes-Benz eArocs 400 Underwent Winter Testing in Finland
Mercedes-Benz Trucks completed winter testing of the new electric truck eArocs 400. The tests took place near the Arctic Circle at temperatures down to −20°C.
What is Known
During the tests, specialists assessed traction and stability on snow and ice, starting at low temperatures, battery and charging performance in cold, as well as the efficiency of the electric powertrain. The data obtained will be used for final model refinement before the start of mass production.
The presentation of the production version is scheduled for April 2026. Production will begin in the third quarter of 2026.
The eArocs 400 is designed for urban construction transportation. While in motion, it produces no local CO₂e emissions and features low noise levels.
Initially, the model will be available in total weight versions of 37 and 44 tonnes with an 8x4/4 wheel configuration and four wheelbase options. The vehicle can be configured as a concrete mixer or construction dump truck. Due to the absence of local emissions, the truck can operate in low or zero-emission zones, and its low noise level makes it suitable for residential areas, areas near hospitals, schools, and kindergartens, as well as for night construction work.
The truck is equipped with a central electric drive with an integrated three-speed gearbox. The continuous power output is 380 kW, with a peak of 450 kW. Combined with proven axle configurations from the Arocs family, this design solution ensures the necessary ground clearance and off-road capability for use on construction sites.
According to the manufacturer, the eArocs 400 is at least 50% more energy-efficient than a comparable diesel truck. This is achieved through higher efficiency of the electric system, energy regeneration, and the use of electric auxiliary units.
The onboard electrical system operates at 800 V. The truck is equipped with two battery packs with a total capacity of 414 kWh, housed in a battery tower just behind the driver's cab. The range of the concrete mixer reaches 200 km, and the dump truck up to 240 km, sufficient for completing most tasks within a full workday without intermediate charging.
Charging is done via standard CCS2 connectors located on both sides of the vehicle. At a power of up to 400 kW, the two batteries can be charged from 10% to 80% in about 46 minutes at a standard high-speed DC charging station with a current of 500 A.
