The new eArocs 400
Charged to change construction.
The eArocs 400, equipped with long-lasting lithium iron phosphate batteries (LFP), is ready for use day and night. Thanks to its all-electric drive, it is ideally suited for quiet, locally CO2‑neutral operation in urban construction traffic.
Range
Enough for a whole day.
With a range of up to 200 km5 as a concrete mixer and up to 240 km6 for the construction tipper, you can easily get through a full working day with the eArocs 400 – with all its challenges. No matter what you use your eArocs 400 for: you can work during the day and recharge comfortably at night.
Robustness
Reliably strong.
Well equipped for use on construction sites: with the familiar robust components of the eArocs 400, you navigate uneven terrain with confidence. Thanks to the powerful Electric drivetrain and high ground clearance, you effortlessly meet the demands of your construction site.
Operational readiness
Ready to go. Round the clock.
The battery-electric drive of the eArocs 400 is significantly quieter than conventional diesel engines. This makes it ideal for noise-sensitive environments and zero-emission zones. With at least 50 % less energy consumption compared with comparable diesel vehicles and a short charging time1, the eArocs 400 is extremely efficient and versatile.
Multimedia Cockpit Interactive 2
Digitally thought through.
The touchscreen of the Multimedia Cockpit Interactive 2 and the ergonomic switch panel provide reliable operation even on uneven terrain. With voice control you can activate numerous functions – without taking your hands off the steering wheel. Applications relevant to you can be accessed via the favourites menu. And with integrated navigation for eTrucks you will not only find the route that suits you, but also charging options along the route.
Safety
Attentive assistants on board.
At the construction site and on the way there: With innovative assistance systems, you are safe on the road. This way you can recognise dangers early, brake in time and keep an overview of the traffic situation.
The Active Brake Assist already meets the AEBS (Advanced Emergency Braking System) legislation, which will come into force in September 2028. The 270° fusion technology features expanded environmental detection. In this way, the system is able to react even faster to critical situations. This enables a higher level of accident avoidance both for vehicles up to 90 km/h and for pedestrians and cyclists up to 60 km/h. The system now also clearly indicates when it is not yet fully active.
The enhanced Active Sideguard Assist in its second generation can support you during lane changes or turning maneuvers with restricted visibility throughout the entire speed range. In addition, the two-stage warning system can alert you to potential hazards so that, by intervening in time, you can defuse a critical traffic situation.
The Frontguard Assist can increase driving safety even before you set off: it monitors the traffic area in front of the vehicle and supports you at speeds up to 15 km/h, e. g. when the vehicle is stationary, when pulling away, or at junctions. If the system detects moving objects in front of the vehicle, such as people, the warning system can help you react in time with a two-stage hazard warning.
Attention Assist 2 can help prevent accidents caused by driver inattention or fatigue by issuing visual and audible warnings. Using an integrated camera, it detects the driver's visual attention based on gaze angle and fatigue level. All data remain in the vehicle.

1 Depending on the equipment.
2 Nominal capacity of a new battery, based on internally defined framework conditions. It may vary depending on the application and environmental conditions.
3 The range was determined under specific framework conditions based on internal simulations with an 8×4 concrete mixer with a permissible gross vehicle weight of 32 t in 8‑h concrete mixer drum operation at an outside temperature of 20 °C, and may deviate from the values determined under Regulation (EU) 2017/2400 due to numerous factors such as topography, weather conditions, speed, preconditioning, auxiliary consumers, the individual vehicle configuration and driving style.
4 The range was determined under specific framework conditions based on internal simulations with an 8×4 construction site tipper with a permissible gross vehicle weight of 32 t in 8‑h tipper operation at an outside temperature of 20 °C, and may deviate from the values determined under Regulation (EU) 2017/2400 due to numerous factors such as topography, weather conditions, speed, preconditioning, auxiliary consumers, the individual vehicle configuration and driving style.
5 The charging time is based on the framework conditions defined in ISO/SAE 12906 for heavy commercial vehicles – with 400 kW charging power at a typical DC fast-charging station with 500 A.
6 Driver assistance systems can only support drivers. Responsibility for the safe operation of the vehicle always remains fully with the driver.
7 Standard in the EU for certain vehicle configurations.
8 With optional equipment S2J, the system can prevent the deactivation of the emergency braking systems Active Brake Assist 6 Plus.
