eArocs 400: first electric construction truck from Mercedes

Mercedes-Benz Trucks’ long-running construction truck, the Arocs, has been electrified for the first time. The Mercedes eArocs 400 debuted at Bauma 2025, the largest construction trade fair in the world, in Munich from April 7th to 15th this year.

The Mercedes Arocs was first introduced in 2013 as a heavy-duty construction truck, succeeding the Axor. Even more than ten years after its debut, the Arocs are still young, with the introduction of its first electric variant: the eArocs 400.

Batteries from the eActros

As the name implies, Mercedes’ first heavy electric construction truck uses a 414 kWh battery, built from two 800V LFP packs right behind the cab. The batteries are shared with the eActros 600 long-range transport truck, but the latter has space for three packs.

They allow for a maximum range of 240 km as a construction tipper or up to 200 km as a cement mixer. This is not massive, but according to Mercedes, the average daily route of a construction truck is less than 100 km.

Up to 400 kW of charging is possible through the CCS2 charging ports, one on each side, which allow for a 20 to 80 percent charge in a minimum of 45 minutes.

The eArocs 400 is powered by a central 450 kW motor (380 kW continuous power), which drives four of the eight wheels (standard 8×4 configuration) through a three-speed transmission.

Concrete mixer or tipper styles

The choice of electric version is more limited than the diesel-powered Arocs. Customers can choose between a 32-ton and a 41-ton variant, with four different wheelbases and the option to build a concrete mixer or construction tipper body. A sleeping cab is also available.

Given the niche product category, Mercedes-Benz Trucks does not plan to sell many eArocs 400 models. Only 150 units are scheduled to be built annually at Daimler Truck’s plant in Wörth, and they will only be sold in the European market.
