Components for the production of batteries at Audi’s Brussels plant will no longer be delivered by truck from Hungary, but by rail with DB Cargo. The move will significantly reduce Audi’s carbon emissions and also save money. The switch in means of delivery between Hungary and Brussels, which was started in May and is scheduled to be completed by the beginning of 2023, is a preview of the car manufacturer’s future.

Brussels plays a pioneering role, but we developed this sustainable logistics concept for battery modules and cells in Audi’s entire production network.

—Dieter Braun, Head of Supply Chain at Audi AG

In the future, preferably all production sites will implement this solution.

Battery modules and cells needed in Belgium for the Audi e-tron and Audi e-tron Sportback were up to now transported by truck over the approximately 1,300-kilometer-long route from the supplier in Hungary. To meet the Belgian site’s demand, twelve to 15 fully loaded vehicles set off across Europe every day. This caravan of trucks is now being replaced by rail transport. The switch will reduce carbon emissions by around 2,600 tons every year.

Wherever possible, Audi uses DB Cargo’s DBeco plus service—for example, currently for the legs of the route in Austria and Germany, the service sources power exclusively from renewable sources such as wind, water, or solar energy, making transport carbon-free. In Hungary and Belgium, Audi uses DBeco neutral. With this product, the power used for transportation is offset by means of climate certificates, reducing carbon emissions elsewhere.

The supplier of the battery modules in Hungary does not have its own rail siding. Therefore, Audi AG’s long-standing project partner DB Cargo recently put a logistics center (LC) into operation at the Győr site. At the weather-protected LC, battery modules are reloaded from trucks to rail cars for delivery. The modules are first picked up from the manufacturer by truck and transported from the Győr LC by rail to Brussels. Initially, a lightweight hall was built in the immediate vicinity of the Audi plant in Győr; an additional expansion is already being planned.

In order to meet the high quality and safety requirements for battery modules and cells, the Audi Supply Chain team uses a digital information platform and special sensor technology to monitor the temperature and any shocks in the rail cars.

The shift pioneered by Brussels is planned to be extended to the entire company in the foreseeable future. High-turnover components, such as battery modules and cells, will increasingly switch to delivery by rail; by 2025, Audi aims to transport these components exclusively by train.

At Audi’s headquarters in Ingolstadt, for example, everything is ready to go for the production of batteries using modules and cells shipped by rail; the batteries will then be used to manufacture Audi models on site. New equipment and processes have been installed specifically for this purpose. Other plants are already waiting in the wings to switch to rail delivery of battery components.

Similarly, a large share of the finished products are also shipped by rail: Today, around 68% of Audi vehicles in Europe already leave the plants by rail, a figure that is set to increase in the future.
