What's new in terms of safety on the Mercedes-Benz eArocs 400?
The new Mercedes-Benz eArocs 400, unveiled at Bauma 2025, places safety at the heart of its value proposition, responding to the expectations of construction and public works companies keen to limit operational risks, protect their teams and optimise their return on investment. The on-board innovations aim to reduce accidents, minimise site interruptions and anticipate European regulatory requirements, while offering practical solutions to the day-to-day challenges faced by professionals.
Here are the main new safety features of the Mercedes-Benz eArocs 400, designed to maximise productivity and peace of mind for operators:
- Active Brake Assist 6 (ABA 6) :
This latest-generation emergency braking system goes beyond the requirements of the EU's General Safety Regulation (GSR). It can now brake automatically at up to 60 km/h if it detects pedestrians, cyclists or vehicles crossing or travelling in the same lane. This significantly reduces the risk of accidents on urban and suburban worksites, where other road users are often present. - Active Sideguard Assist 2 :
This device monitors blind spots and, if a hazard is detected during a low-speed manoeuvre (up to 20 km/h), it can automatically trigger emergency braking if the driver does not react to the alerts. This feature exceeds current standards that only require an audible or visual warning, providing added safety when making tight bends or manoeuvring on site. - Front Guard Assist :
This system detects obstacles and road users in front of the vehicle, an invaluable aid when manoeuvring in the confined spaces of urban or residential worksites. It helps avoid collisions at low speeds, protecting pedestrians and equipment on site. - ESP as standard and advanced connectivity :
The arrival of ESP (electronic stability control) as standard, combined with on-board connectivity (Multimedia Cockpit Interactive 2 with voice control), means that emergency situations can be better managed and risks anticipated, while simplifying access to safety functions for the driver. - Regulatory compliance and anticipation :
All these systems meet or exceed the latest European GSR standards, anticipating future regulatory changes. This represents a long-term investment for companies, avoiding future upgrade costs and securing their fleets for the long term.
In short, the Mercedes-Benz eArocs 400 offers cutting-edge safety, designed to reduce accident-related costs, improve vehicle availability and meet the growing demands of the construction industry. These innovations enable companies to focus on the productivity of their worksites, while protecting their employees and enhancing their brand image in the eyes of their clients.
