WABCO says its OptiFlow AutoFlow is the first aerodynamic tail in the U.S. to feature automatic deployment and retraction, as well as the first product to earn EPA SmartWay verification from the prestigious National Research Council (NRC), the Canadian government’s premier research and technology organization. WABCO says the tail 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. Then the tail panels automatically retract at a vehicle speed of 10 mph, the company says.
According to WABCO, the OptiFlow AutoTail delivers fuel savings of up to 4.3 percent at highway speeds based on SmartWay test protocol, and reduces CO₂ emissions by up to 4.8 tons per trailer per year. Automatic retraction 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, the company says.
WABCO also is featuring its OptiFlow Tail this week. Easy to deploy and retract manually, WABCO OptiFlow Tail provides identical fuel savings as OptiFlow AutoTail. It features a lightweight design that is straightforward to install and retrofit. OptiFlow Tail is easily upgraded to OptiFlow AutoTail, WABCO says.
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. WABCO says the injection-molded panels offer a unique, curved shape and smooth surface that reduces air resistance.
“We are proud to introduce an array of innovative aerodynamic solutions in North America that will improve efficiency of commercial vehicles for fleet operators and transport companies alike,” says 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.”
“Having combined the strengths of two technology pioneers, WABCO is advancing aerodynamics to make an even more significant difference in the efficiency of commercial vehicles,” says Brian P. Layfield, WABCO Global Aerodynamics Leader and former President of LCL. “Our OptiFlow products feature state-of-the-art design, materials and technologies that enable fleets to optimize fuel efficiency while improving vehicle safety and operating convenience.”
