In a unique series of experiments using full sized vehicles, which was sponsored by the Department of Industry, the aerodynamic drag of a truck has been measured in the MIRA full-scale wind tunnel and the drag reducing effects of a range of proprietary add-on devices investigated. The test vehicle was a Ford D1614 with the flat bed replaced by a container which was moveable to represent either a rigid truck, where the container was closed up to the driver's cab, or an articulated truck with a representative gap between the cab and the trailer. To establish a relationship between the indicated drag reduction and fuel savings, steady speed fuel consumption measurements were made on a test track using the unladen vehicle fitted with many of the devices tested in the wind tunnel. For simplicity, devices which were similar to each other were grouped into one family and one representative device tested on the track. Following these tests the vehicle was driven round a 356 km road test route with and without a device fitted and the fuel consumption measured at frequent intervals.
