Mercedes-Benz Trucks has launched sales of its new battery-electric eArocs 400, expanding its electric portfolio to include the construction segment. The locally CO₂e-free and low-noise electric truck celebrated its world premiere last year at bauma, the world’s largest construction equipment show, held in Munich, Germany.
Equipped with two lithium-iron-phosphate (LFP) battery packs – each offering 207 kWh of installed capacity and housed in a battery tower behind the cab – the eArocs 400 demonstrates the strong potential of battery-electric vehicle solutions in the construction industry.
Designed specifically for urban and near-road construction work, the eArocs 400 enables full-day operation without intermediate charging, according to the manufacturer.
Stina Fagerman, Head of Marketing, Sales and Services at Mercedes-Benz Trucks, states: “With the new battery-electric eArocs 400, we are enabling locally CO₂-free operations even in demanding construction environments. The vehicle combines the robustness required with an efficient electric drive system, covering key use cases in near-road construction. This supports our customers in sustainably advancing and future-proofing their fleets.”
Available variants
The eArocs 400 is initially offered in two versions with technically permissible gross vehicle weights of 37 and 44 tonnes. It is available in an 8x4/4 axle configuration and four wheelbase options.
The vehicle is suitable for applications such as dump bodies and concrete mixer bodies, and it can operate in low- and zero-emission zones. Its low noise emissions also make it ideal for residential areas and nighttime construction sites, according to Mercedes-Benz.

Powerful batteries
Key components from the second-generation Mercedes-Benz eActros portfolio have been incorporated into the eArocs 400. These include the front box and the power take-off (PTO), as well as the LFP)battery technology, which offers a long service life and particularly high usable capacity. Thanks to its significantly higher efficiency and additional energy-saving potential – for example through recuperation and electrically powered body functions – the eArocs 400 is at least 50 per cent more energy-efficient than a comparable diesel truck, the company claims. The vehicle operates with an 800-volt onboard electrical architecture.
Long range and fast charging capability
For many use cases, the eArocs 400 can complete a full workday without intermediate charging. In concrete mixer operation, it offers a range of up to 200 km, and in dumptruck operation up to 240 km. The truck supports charging at up to 400 kW via the standard CCS2 charging interface, available on both sides of the vehicle. The two battery packs need approximately 46 minutes to charge from 10 to 80 per cent.
Electric drivetrain
The electric truck features a powerful central drive with an integrated three-speed transmission, providing a continuous output of 380 kW and a peak output of 450 kW. Combined with the proven hypoid and planetary axles from the Arocs, the vehicle offers the required ground clearance and off-road capability for construction-site operations.
Robust vehicle concept
The eArocs 400’s tandem drive axles ensure sufficient traction both on and off the road. Proven components such as the robust vehicle frame and steel suspension on the front and rear axles provide the necessary durability for daily construction work. The M-cab features a low-maintenance interior, additional storage options and an optional berth. It is fully galvanised and enables maximum body length while maintaining excellent manoeuvrability.
Digital Cockpit and Assistance Systems
Even on uneven terrain, the Multimedia Cockpit Interactive 2 in the eArocs 400 can be operated confidently, thanks to its improved ergonomic switch panel and voice control. Modern safety assistance systems, including Active Brake Assist 6 Plus, Active Sideguard Assist 2 and Front Guard Assist, support drivers in detecting hazards early, braking in time when necessary and maintaining situational awareness on the road and on construction sites.
Sustainability
Sustainability is an integral part of the Mercedes-Benz Trucks strategy. As part of Daimler Truck – one of the world's largest commercial vehicle manufacturers, with over 40 main locations and more than 100,000 employees around the globe – Mercedes-Benz Trucks is committed to contributing to the decarbonisation of road freight transport and driving the transformation of the transport industry. Through battery-electric and hydrogen-based drive technologies, digital services, and climate-friendly, resource-efficient production and supply processes, Mercedes-Benz Trucks is helping to pave the way toward locally CO₂e-free transport across the entire value chain.
