Abstract
Disclosed is a vehicle including a tractor having a lower tractor duct that receives air from the front of the tractor and channels the air through a center area of the tractor and down between a set of rear wheels, a trailer having a lower trailer duct positioned below a cargo space that channels the air in the lower trailer duct between each set of trailer rear wheels and a lower articulation duct positioned near the set of tractor rear wheels that receives air from the lower tractor duct and communicates air to the lower trailer duct. An upper duct channels air through ductwork at the top of the trailer and tractor. A rear trailer louver system enables air in each duct to be channeled and pulled out of each respective duct, reducing drag and eddy currents using the vacuum at the rear of the trailer.
