Agility Fuel Solutions and XStream Trucking Inc. announced Agility will be the exclusive distributor of XStream’s TruckWings aerodynamic systems on compressed natural gas trucks in North America.

Aerodynamic devices intended to calm turbulence and improve fuel efficiency for heavy-duty vehicles come in many shapes and sizes — from wheel covers to fairings over, under and behind trailers. Now a group of investors has provided additional support to XStream Trucking Inc., whose TruckWings device automatically encloses the area between the tractor and trailer.

XStream Trucking Inc. launched its aerodynamic device called TruckWings to address the gap between a Class 8 truck and trailer when at highway speeds.
