ABSTRACT This invention relates to an air flow diverter for reducing the aerodynamic drag of a vehicle having a front roof portion and a rear roof portion at a higher level than the front roof portion. The diverter comprises a plurality of superimposed laminar elements,the lowermost of which is adjacent the front roof portion of the vehicle. Each other laminar element has its front edge disposed in proximity to the laminar element below it, defining therewith a transverse entrance slit. Each pair of adjacent laminar elements furthermore define a divergent duct downstream of the respective entrance slit. In operation of the vehicle, a part of the air flow passes through the divergent duct, increasing in pressure to establish a high pressure region downstream of the diverter, substantially fixed relative to the vehicle, which encourages the deflection of the principal part of the air flow over the roof and sides of the vehicle- when the vehicle is in motion.
