Abstract
A gap fairing and aerodynamic drag reduction method for a tractor-trailer. A fairing body is attached to a chassis of the tractor, independently of the cab thereof and within a gap between a cab of the tractor and the trailer. The fairing body has side portions, extending rearwardly from a front portion, adjacent the cab of the tractor, toward the trailer and an upwardly sloping top portion extending to the side portions and terminating in a trailing end. The trailing end can be situated behind the side portions to lessen the inclination of the top portion. A separation space between the front of the fairing body and the cab can be sealed by a sealing element that is at least in part resilient or flexible or both so as to allow relative motion between the fairing body and the cab.
