Sustainable and flexible production: The series-production model of the eActros will be produced in Wörth

  • The electric truck models are manufactured flexibly in the Wörth plant alongside trucks with a conventional drivetrain.
  • eActros production is wholly integrated in the drivetrain and vehicle production network of Mercedes-Benz Trucks.
  • The network also includes the processing and assembly of the main electric drive components in the Gaggenau (components for the electric axle), Kassel (assembly and testing of the electric axle) and Mannheim (assembly of the HV battery packs) plants, as well as vehicle production in the Wörth plant.

At the heart of eActros series production is the production hall in building 75 of the Wörth plant. In recent months intensive preparations have been made for the new production processes there. This includes the construction of a new assembly line. It is mainly used for the installation of high-voltage (HV) components – including the battery packs from the Mannheim plant's centre of competence for emission-free mobility (KEM for short) – and the commissioning of finished vehicles. The vehicles are then conveyed back to the finishing section and final inspection as part of the regular production process.

In the Wörth plant, Mercedes-Benz Trucks has established a specific HV organisational structure. What's more, the HV experts have to undertake a special qualification at the location's own training centre to enable them to work on the eActros. As part of this, they cover a number of modules concerning the special components and working with HV components and electric trucks.

In the assembly hall, the electric truck models are manufactured flexibly alongside trucks with a conventional drive system. In essence, the manufacturing of different vehicle types should take place in as integrated a manner as possible, and the basic structure of the vehicle should be made on a single production line, regardless of whether it is fitted with a conventional combustion engine or an electric drivetrain.

An example of this is the electric axle used on the vehicle which stems from the Mercedes-Benz Kassel plant. There, the electric axles and the entire electric drivetrain – made up of the electric motor and activatable transmission elements – is assembled and the final checks carried out with an emphasis on correct functioning, high-voltage safety and noise behaviour. As the electric axle has principally the same basis as the conventional model series, it can be pre-assembled on the existing production line in parallel to the regular model series.

Mercedes-Benz Trucks therefore uses the available infrastructure in the assembly hall, whilst simultaneously increasing its flexibility of production unit numbers for the individual model series. With this in mind, the transformation from conventional to electric model series can be actively implemented.
