OptiFlow™ Savings Calculator


Aerodynamic research at the Delft University of Technology reveals that the underside of a trailer creates a huge aerodynamic drag, resulting in high fuel consumption.

WABCO’s OptiFlow™ SideWings improves the aerodynamics of the trailer by capturing the airflow at the lower end of the tractor and guiding it all the way towards the tail end of the trailer along the rotating wheels.

Fitting OptiFlow™ SideWings to your trailer fleet substantially reduces fuel consumption by around 1.5l/100km (at highway speeds) lowering the carbon footprint and generating significant cost-savings over the lifetime of the vehicle.

Calculate your potential fuel savings based on trailer's annual mileage at highway speed, fuel price and fleet size. Either for one product or for the combination of both, Tail and SideWings.
