WABCO Launches Aerodynamic Solutions for Trailers in North America

WABCO Holdings (NYSE: WBC), a leading supplier of technologies focused on safety, efficiency and connectivity of commercial vehicles, has announced the North America premiere of OptiFlow™ AutoTail and Tail, an aerodynamics technology.

OptiFlow AutoTail deploys and retracts tail panels based on driving speed as determined by sensors linked to WABCO’s Trailer Anti-Lock Braking Systems (ABS). The device automatically deploys at vehicle speeds of 45 mph ensuring it is consistently used at speeds that maximize aerodynamic fuel savings. The tail panels automatically retract at a vehicle speed of 10 mph.

According to the company, the approach delivers fuel savings of up to 4.3% at highway speeds based on SmartWay test protocol, and reduces CO₂ emissions by up to 4.8 tons per trailer per year. Automatic retraction, WABCO noted, also improves maneuverability and enhances safety by ensuring panels are folded in city centers, loading docks and other areas where trailers are in close proximity to pedestrians or objects.

Both OptiFlow Tail and AutoTail are made from automotive grade thermoplastic, an extremely lightweight, durable and long-lasting material that resists wear from weather, vibration and everyday hazards of the trucking industry. The injection-molded panels offer a unique, curved shape and smooth surface that reduces air resistance.

Noted Jon Morrison, WABCO President, Americas, “WABCO’s OptiFlow AutoTail and Tail represent our first product integration in North America after we acquired aerodynamic technology leader Laydon Composites Ltd. (LCL) in April 2016. Based on our combined world-class aerodynamics expertise, design and manufacturing capabilities we deliver aerodynamic solutions that will help our fleet customers meet U.S. greenhouse gas emission regulations to take effect in January 2018.”
