Mercedes-Benz has unveiled a concept for an "Aero Trailer" that the company says can improve big rig fuel efficiency through a dramatic reduction in aerodynamic drag.

The full-size trailer has been fitted with a front air dam, wheel-covering side skirts, tapered tail extensions, underbody panels and a parallelogram-shaped rear diffuser similar to those found on racing cars.

When hooked up to Mercedes-Benz' all new Actros tractor the changes contribute to an 18 percent reduction in aerodynamic drag.

Tractor trailers currently consume approximately 45 billion gallons of fuel each year in the United States. According to Mercedes-Benz, the "Aero Trailer" design could improve fuel economy by approximately 5 percent, saving more 500 gallons of fuel for every 90,000 miles driven.
