OptiFlow

Optimizing long-haul trailer aerodynamics

OptiFlow™ targets drag reduction

WABCO’s OptiFlow™ utilizes the latest aerospace research tools and methodologies to deliver step-change in long-haul trailer aerodynamics. OptiFlow™ SideWings and OptiFlow™ Tail have been developed specifically for the European market aiming distinctly and cost-effectively reducing highway fuel consumption. OptiFlow™ technologies target the cost of drag and reduce it. Through simple–to–retrofit components, OptiFlow™ demonstrably reduces a trailer’s coefficient of drag, creating a more aerodynamic profile that lowers emissions and reduces fuel costs. The more highway kilometers your trucks drive, the bigger the cost savings OptiFlow™ can provide.

While aeroplanes are inherently aerodynamic, trucks are not – and so lowering the drag coefficient for a truck was always going to be a challenge. Designed for maximum load, rather than minimum drag, the truck is a complex aerodynamic shape: it is characterized by heavily separated flow regions; it suffers unstable flow behavior and interacts with the road surface and surrounding objects in ways that an aeroplane does not. OptiFlow™ represents a breakthrough in the field of trailer aerodynamics.

 
 
 

Having been largely ignored until recently, the potential is huge for cost savings through aerodynamic upgrades to a trailer fleet. A more aerodynamic trailer is a more economical truck. And while the science behind the aerodynamic design is complex, the retrofitting process is simple. WABCO’s expertise in the field of trailer aerodynamics, combined with many years of experience in the commercial vehicles aftermarket, make it the perfect partner to deliver the aerodynamic upgrade to make fleets more effective.

Aerodynamic resistance accounts for over half the drag experienced by a tractor-trailer combination driving at highway speeds, with the trailer being a large contributor. Employing the latest aerodynamic technology, in particular to the rear-end and undersides of the trailer, has enabled significant drag reduction. In combination with other technologies, such as WABCO’s OptiLevel™, which intelligently adjusts chassis height, trailer drag can be decreased by up to 26 per cent, resulting in sizeable fuel savings.
