The locally CO2 -free and low-noise electric truck will celebrate its world premiere at this year’s bauma in Munich from 7 to 13 April. Mercedes-Benz Trucks is once again highlighting the innovations the company is using to drive forward the transformation to CO2-neutral drives on the vehicle side and how these solutions also benefit the construction industry.
A small series of 150 vehicles per year is currently planned for the eArocs 400 for selected EU30 markets. The vehicle will initially be available as a 32- and 41-ton variant in the 8x4 axle configuration with four different wheelbases and can be built as a concrete mixer or construction tipper. It thus covers essential applications for street-oriented construction transport.
Thanks to its local CO2 neutrality during driving, the eArocs 400 can enter low-and zero-emission zones in inner-city areas and is also suitable for noise-sensitive environments such as residential areas, the environment of hospitals, schools and kindergartens as well as for night-time construction sites due to its low noise emissions. The start of sales is scheduled for the 1st quarter of 2026, the first delivery in the 3rd quarter of 2026.
Achim Puchert, CEO Mercedes-Benz Trucks, said: "With the new eArocs 400, we are now also bringing electrification to the construction industry, which is particularly important for our economy and society. Following the distribution and long-haul transport, we are continuing to expand our product range of battery-electric trucks.
"Now, it is crucial that policymakers promote the development of the charging infrastructure and create the necessary framework conditions for the economic operation of these vehicles."
For the new eArocs 400, Mercedes-Benz Trucks is adopting essential components from the eActros 600. In addition to the front box and the power take-off (PTO), this also includes the batteries based on lithium iron phosphate cell technology (LFP). These batteries feature in particular a high durability and a particularly high usable battery capacity.
Due to its significantly higher efficiency, the eArocs 400 is at least 50 percent more energy-efficient than a comparable diesel truck. It has an on-board electrical system voltage of 800 volts and two battery packs with an installed battery capacity of 414 kWh located in the battery tower directly behind the driver’s cab.
The range as a concrete mixer is up to 200 kilometres without intermediate charging. Customers typically drive in single-shift operation, cover average daily routes of less than 100 kilometres and travel almost exclusively on paved roads. This makes the e-truck predestined for this application.
With the construction tipper variant, the range increases to up to 240 kilometers2 without intermediate charging. The eArocs 400 can be charged with up to 400 kW via the standard CCS2 charging socket mounted on both sides of the vehicle. The two battery packs need
approximately 45 minutes to charge from 20 to 80%.
The eArocs 400 is fitted with a powerful central engine with a 3-speed transmission and a continuous power of 380 kW and a peak performance of 450 kW. In combination with this technical powertrain solution, the tried-and-tested planetary axles of the Arocs can be used to continue to offer the ground clearance and off-road capability required for construction site deployment.
