Sales launch for Mercedes eArocs 400 construction truck
Since 2013, Mercedes-Benz Trucks has positioned the Arocs as a truck tailored for the construction industry—until now, powered exclusively by diesel. Just over a year ago, Mercedes-Benz Trucks unveiled the eArocs 400 for the first time and scheduled its premiere for last year’s Bauma Munich trade fair. Since then, the technical specifications have confirmed that, like the long-haul eActros 600, the eArocs uses LFP battery cells and is available as a mixer or tipper. At the time, the Daimler Truck subsidiary also confirmed that the eArocs 400 would be produced in a small series of 150 vehicles per year for selected EU markets.Sales have now officially commenced, initially in 13 countries – specifically in Germany, Switzerland, Austria, France, Spain, Belgium, Luxembourg, Denmark, Sweden, Norway, the Netherlands, Finland, and Iceland. Stina Fagerman, Head of Marketing, Sales and Services at Mercedes-Benz Trucks, stated: “With the new battery‑electric eArocs 400, we are enabling locally CO₂-free operations even in demanding construction environments.” The vehicle combines robustness with an efficient electric powertrain and covers key applications in near-road construction transport. The manufacturer has also ensured the model can withstand cold and icy conditions through a recently completed winter testing programme.Key point: The eArocs 400 retains the sturdy vehicle frame and steel suspension from its diesel counterparts. However, it also incorporates core components from Mercedes-Benz Trucks’ second-generation electric trucks. This generation is based on the modular system introduced two years ago with the eActros 600. In addition to the batteries, these components include the front box and the Power Take-Off (PTO).In terms of battery technology, the construction site truck uses two of up to three LFP battery packs, each with 207 kWh – totalling 414 kWh. However, the positioning differs: while the eActros series carries the batteries between the axles, the eArocs features a battery tower, which the Paul Group installs directly behind the cab. The 800-volt system is charged at up to 400 kW via the standard CCS2 ports located on both sides of the vehicle. According to the manufacturer, the two battery packs take approximately 46 minutes to charge from 10 to 80 percent.

The tandem drive axles of the eArocs 400 are also designed to provide sufficient traction on and off the road.Initially, the eArocs 400 will be available with a technically permissible gross vehicle weight of 37 and 44 tonnes in the 8×4/4 axle configuration and in four different wheelbases—including as a mixer or tipper, which, according to Mercedes-Benz Trucks, “covers essential applications for near-road construction transport.” As a mixer, the range is up to 200 kilometres, while the tipper variant achieves up to 240 kilometres. “For many use cases, the eArocs 400 can complete a full workday without intermediate charging.,” the company states. Regarding the cab, the M-cab is “features a low‑maintenance interior, additional storage options and an optional berth. It is fully galvanized and enables maximum body length while maintaining excellent manoeuvrability.”daimlertruck.com, mercedes-benz-trucks.com
