The testing of three truck and trailer rigs using various designs of aerodynamic devices has revealed the effectiveness of air defectors and stabilizers as fuel economy devices. In the tests which covered 6,000 miles, two vehicles used aerodynamically shaped structures attached to the roof of the tractor, and a flexible vertical membrane to seal the gap between the tractor. The third vehicle had no added devices. on vehicle using the deflector consumed 12 percent less fuel than an identical 5-axle rig without a deflector. The fule savings were equivalent to 2,400 gal. of fuel per 100,000 miles. The second vehicle with airshield and stabilizer showed a fuel saving of 6 percent of 12,000 gal. of fuel per 100,000 miles.
