Wabco has unveiled a new aerodynamic semi-trailer fin to boost fuel efficiency for trailers.
The OptiFlow Tail – showcased at IAA in Hanover (25 September to 2 October) – features four folding panels to improve air flow at the back of the trailer, and is available for new trailers or as a retrofit option.
The durable panels are mounted directly on the trailer's swing doors, allowing the doors to open fully.
Wabco says, in tests, the product enabled a tractor-trailer combinations to achieve 3.5% better fuel economy at highway speeds.
When used with OptiFlow SideWings – Wabco's flow-conductor to optimise airflow around and under the trailer – fuel savings can be up to 7%, says the company.
