Mercedes-Benz Trucks Opens Sales for Electric eArocs 400

Leinfelden‑Echterdingen- Mercedes-Benz Trucks has opened sales for its new battery-electric eArocs 400, marking its entry into the electric construction truck segment. The model, first unveiled at bauma in Munich last year, is designed for urban and near-road construction work where low noise and zero local emissions are increasingly important.

The eArocs 400 is equipped with two lithium-iron-phosphate battery packs, each with 207 kWh of installed capacity, mounted behind the cab in a battery tower. Built for demanding daily operations, the truck is intended to complete a full working day without needing intermediate charging. Customers in 13 initial EU markets can place orders now, while production of the base vehicle is scheduled to begin in the third quarter of 2026 at Mercedes-Benz’s Wörth am Rhein plant, with electric drivetrain integration to be carried out by Paul Group in Vilshofen an der Donau.

Mercedes-Benz Trucks says the eArocs 400 combines the toughness expected from the Arocs range with an efficient electric powertrain suited for construction environments. The truck is initially available in 37-tonne and 44-tonne gross vehicle weight variants, both in an 8x4/4 axle configuration, with four wheelbase options. It is designed for use with applications such as dump bodies and concrete mixers, while also being suited for low- and zero-emission zones, residential projects and night-time construction work due to its quiet operation.

Drawing on technology from the second-generation eActros lineup, the eArocs 400 features an 800-volt electrical architecture and uses components such as the front box and power take-off from the electric truck platform. Mercedes-Benz Trucks states that the vehicle is at least 50 percent more energy-efficient than a comparable diesel truck, helped by high drivetrain efficiency, recuperation and electrically powered body functions.

In terms of operating range, the truck can travel up to 200 km in concrete mixer use and up to 240 km in dump truck operation. It supports charging at up to 400 kW through CCS2 charging ports on both sides of the vehicle, allowing the batteries to be charged from 10 to 80 percent in about 46 minutes.

Power comes from a central electric drive paired with an integrated 3-speed transmission, delivering 380 kW continuous output and 450 kW peak output. Mercedes-Benz Trucks says this setup, combined with proven hypoid and planetary axles, provides the ground clearance and off-road capability required for construction-site conditions. Tandem drive axles, a robust frame and steel suspension are intended to ensure durability and traction across varied terrain.

Inside, the truck features the Multimedia Cockpit Interactive 2 with ergonomic controls and voice operation, helping drivers manage functions more easily even on rough ground. Safety technologies include Active Brake Assist 6 Plus, Active Sideguard Assist 2 and Front Guard Assist, aimed at improving hazard detection and driver awareness both on the road and at work sites.

With the launch of the eArocs 400, Mercedes-Benz Trucks is extending its sustainability strategy into the construction sector, supporting the shift toward lower-emission transport solutions through battery-electric technology and more resource-efficient operations.
