The exterior of the CoolerBox has been re-engineered with a view to aerodynamics: optimised radii distinguish the front of the refrigerated truck body and foster a smooth transition to the side panels. The fittings on the tailgate and side doors are built flush with the doors and thus provide improved protection against theft. The lighting elements are protected by flush mounting at the front. This creates smooth, relaxed exterior surfaces that not only enhance the drag coefficient but are also characteristic for the new, clear aesthetics of the truck body.
