Mercedes-Benz Advances E-Mobility Offensive for Commercial Vehicles with New eArocs 400
Leinfelden-Echterdingen (Germany) - With the new Mercedes-Benz eArocs 400, Mercedes-Benz Trucks underscores its strategy to develop battery-electric commercial vehicles tailored for different transport segments. After successful winter testing under extreme conditions, another milestone has been reached on the path to series production.
The New eArocs 400: Robustness for Urban Construction Traffic
The eArocs 400 impressively demonstrated its everyday usability during winter testing in Finland at temperatures down to -20°C. Key focus areas included traction and driving stability on snow and ice, battery and charging performance in extreme cold, and the capabilities of the electric drivetrain including recuperation.
With an installed battery capacity of 414 kWh (two LFP battery packs) and an 800-volt architecture, the eArocs 400 achieves a range of up to 200 km as a mixer truck or up to 240 km as a tipper, depending on the configuration. Charging is possible up to 400 kW via CCS2; charging from 10% to 80% takes approximately 46 minutes.
The central drive with integrated 3-speed transmission delivers 380 kW continuously and up to 450 kW peak. In combination with proven hypoid and planetary axles as well as a robust chassis concept, the essential ground clearance and off-road capability for construction site operations are maintained.
The base vehicle will be produced from the third quarter of 2026 at the Wörth am Rhein plant, with integration of the electric drivetrain by the Paul Group in Vilshofen an der Donau. Sales are scheduled to begin in April.
The eArocs 400 thus represents locally CO₂-free and low-noise transport in near-site construction traffic – including operation in low- and zero-emission zones as well as noise-sensitive areas.
The eActros 600: Range Flagship for Long-Haul Transport
In contrast, the eActros 600 is designed specifically for heavy long-haul transport. With a battery capacity of around 600 kWh, it enables ranges of approximately 500 km without intermediate charging.
The vehicle concept focuses on maximum efficiency at highway speeds, aerodynamic optimization, and high continuous performance for Europe-wide freight transport. While the eArocs operates on construction sites with short, predictable daily distances, the eActros 600 addresses long routes, international logistics, and high annual mileage.
Both models share key components such as LFP battery technology and parts of the electric drivetrain portfolio but are consistently tailored to their respective operational profiles.
Similar Naming, Different Operational Worlds
The similar names “Arocs” and “Actros” have historical roots. Both belong to Mercedes-Benz Trucks’ heavy-duty family but serve different segments – construction traffic (Arocs) and long-haul transport (Actros).
The numbers also follow a clear system. In the eActros 600, the number corresponds directly to the roughly 600 kWh battery capacity. In the eArocs 400, the “400” signals a lower power and operational class within the portfolio.
This creates a logical tiering: 400 stands for a robust, regionally deployed construction vehicle, 600 for a long-range flagship for long-haul transport.
The similar nomenclature ensures recognition within the e-mobility strategy, while the different numbers allow clear positioning within the product portfolio. Mercedes-Benz Trucks appears to aim at implementing the transition to locally emission-free drivetrains precisely for each segment, from urban construction sites to international long-haul routes.
