- Mercedes-Benz eArocs 400 successfully completed Arctic winter testing at -20*C to validate performance and battery efficiency.
- Series production begins in 2026 with advanced LFP batteries, 800-volt architecture, and 400 kW fast charging capability.
The Mercedes-Benz eArocs 400 has successfully completed rigorous winter testing near the Finnish Arctic Circle, proving its capability to operate reliably in extreme cold conditions. Conducted in temperatures as low as -20?C, the tests evaluated traction, stability, cold-start behavior, battery efficiency, charging performance, and regenerative energy recovery. The results provide valuable engineering data to refine the electric truck before it enters series production. With its advanced battery system and high-voltage architecture, the Mercedes-Benz eArocs 400 demonstrates how heavy-duty electric vehicles can maintain efficiency and durability even in harsh climates.
Extreme Cold Winter Testing Validates Performance
The winter testing program focused on ensuring stable operation on snow and ice while maintaining consistent energy output. Engineers examined how the electric truck handled reduced temperatures that typically impact battery chemistry and charging efficiency. Traction control and driving stability were closely monitored to confirm safe maneuverability under slippery conditions.
Battery and Energy Recovery Assessment
Particular attention was given to lithium iron phosphate batteries and their response to sub-zero environments. The evaluation included charging behavior, cold-start functionality, and regenerative braking efficiency. Testing confirmed that the system maintained dependable performance, supporting optimized energy recovery even in demanding winter scenarios.
Production Timeline and Manufacturing Strategy
The Mercedes-Benz eArocs 400 is scheduled to go on sale in April 2026. Base vehicle production will begin in the third quarter of 2026 at the Mercedes-Benz plant in W?rth am Rhein, Germany. Integration of the electric powertrain will be carried out by the Paul Group in Vilshofen an der Donau, Germany, ensuring specialized expertise in electrified heavy-duty platforms.
High-Efficiency Electric Powertrain Architecture
Built using core components from the eActros range, the truck incorporates lithium iron phosphate batteries and operates on an 800-volt electrical system. The configuration includes two battery packs delivering a total capacity of 414 kWh. Compared to a conventional diesel counterpart, the vehicle achieves at least 50 percent greater energy efficiency, reinforcing its suitability for urban construction applications.
Power Output and Drivetrain Configuration
The central electric drive is paired with a three-speed gearbox, delivering continuous power of 380 kW and peak output of 450 kW. This setup ensures consistent torque delivery and optimized drivability for demanding construction tasks.
Range and Fast Charging Capability
The Mercedes-Benz eArocs 400 offers a range of up to 200 km in concrete mixer configuration and up to 240 km as a tipper. It supports fast charging up to 400 kW via CCS2, enabling the battery to recharge from 10 percent to 80 percent in approximately 46 minutes. This rapid charging capability enhances operational uptime while supporting efficient fleet deployment.
With validated winter testing results, advanced battery technology, and high-power charging support, the Mercedes-Benz eArocs 400 marks a significant step toward electrified heavy-duty construction transport in challenging environments.
