Strakes on the top and sides of the trailer generate vortices, which
diffuse and direct momentum into the trailer's wake region. The resulting
upwash and inwash flows increase the pressure on the base of the trailer
and reduce drag. This technology has undergone extensive road testing.
Fuel savings of between 2 to 3 percent were demonstrated in the wind
tunnel and road tests of this technology. For an in-depth analysis
of the road tests of this technology download
