A study concluded that if a tractor’s two side mirrors were removed, the tractor would burn 938 fewer litres of fuel annually based on current fleet wide average fuel consumption values.
Some manufacturers are currently designing prototype vehicles that use rear facing cameras and in-cab video screens that replace the side view mirrors.
The purpose of this study is to better understand what technologies or practices can be applied to highway tractor and trailer combinations and highway motor coach buses to reduce aerodynamic drag without negatively affecting the usefulness or profitability of the vehicles.
Additionally, it is of interest to determine how these devices may affect other vehicles and vulnerable road users in close proximity to the tractor trailers or buses.
And if so, what configuration would be best suited to optimize drag reduction between the two trailers of an LCV.
