A wind tunnel investigation into the effects of roof curvature on the aerodynamic drag experienced by a light goods vehicle [PDF]
, 2015 Roof curvature is used to increase ground vehicle camber and enhance rear-body boat-tailing to reduce aerodynamic drag. Little aerodynamic data is published for light goods vehicles (LGVs) which account for a significant proportion of annual UK licensed ...
