According to a report by In a report by Heavy Duty Trucking, the test show that trailers with side skirts consumed an average of 6.69% less fuel than similar vehicles without skirts. Trailers with undercarriage aerodynamic devices consumed 1.43% less fuel on average than similar units without the deflectors.
PIT’s trailer aerodynamic device tests were performed at the Transport Canada Motor Vehicle Test Centre in Blainville, PQ.
“There’s a lot of confusion in the industry about the skirts and undercarriage technologies, so we want to try to clarify the issue,” Yves Provencher, director of PIT, told HDT.
The next results to be released by PIT will be a fuel economy challenge between a typical North American conventional truck with a typical European COE design.
