Insights of the ORCA Transporter and building it

When developing the Orca Transporter, reducing air resistance was the key factor in achieving maximum efficiency. Every curve and every edge of the outer skin was designed with the aim of significantly reducing fuel consumption and maximizing range through aerodynamic precision. Instead of relying on conventional designs, we derived the vehicle's shapes directly from the physical requirements of fluid dynamics.

We achieved the decisive breakthrough by using state-of-the-art CFD simulations with Simcenter STAR-CCM+. In this digital wind tunnel, we were able to visualize the airflows and refine the outer skin geometry in countless iterations. This targeted aerodynamic optimization enabled a significant reduction in the drag coefficient. The result is a high-performance vehicle shell that minimizes drag and thus increases efficiency on every kilometer without placing unnecessary strain on the engine.

In the construction of the Orca Transporter, engineering expertise and innovative design merge to form a functional unit. The CFD-optimized outer skin is not only an aesthetic feature, but the result of data-driven development that shows how modern flow simulation is defining the mobility of tomorrow. This technological depth enables us to achieve a level of efficiency that sets new standards in vehicle manufacturing and makes the Orca a pioneer in resource conservation.

Quality and durability are key features of the Orca transporter. To prove this, the first prototype underwent rough road testing. Legislators only require a calculation to verify the stability of transporters, but the developers and test engineers at Reiter behind the Orca's development demand more. The supreme discipline is called rough road testing. This term refers to the Orca being put through its toughest terrain. In the demanding rough road test, one kilometre on selected bumpy roads corresponds to around 100 kilometres in practice.

The numerous tracks at the test centre in Markbronn represent typical road surfaces such as headstone paving, transverse grooves and potholes. They put the vehicle structure through extreme stress. Reiter's test team has put together defined tracks for the test to form a rough road course. The driving programme is precisely specified, both in terms of the sequence of tracks and the speed. Proof of the extreme nature of the programme: although the shock absorbers have special cooling during the test, they have to be replaced twice during the entire period.
