The article reports that haulage industry could increase fuel economy by up to five per cent using airflow control techniques developed in the U.S. by the Georgia Institute of Technology in Atlanta, Georgia and Volvo Car Corp. Researchers claimed that this would potentially save the industry thousands of pounds. The research, supported by the U.S. Department of Energy and Volvo Trucks of north America, uses pneumatic devices to blow air from slots at the rear of the truck's trailer. This improves airflow and prevents its separation in order to minimise aerodynamic drag, thereby saving fuel.
