America's Environmental Protection Agency (EPA) has proposed a new method for determining a vehicle’s true fuel economy rating, including a ‘test track’ component.

The new approach would see carmakers first put new models through laboratory-based testing, before submitting to a track test to determine a more accurate average fuel-use figure.

Variables such as wind speed, track temperature and weather conditions would be noted, with corrections made to the final figure, if need be, to ensure an even playing field for all carmakers.

The proposed method would present new challenges, with true aerodynamic advances and rolling resistance of tyres holding more significance on the road than in the controlled environment of current testing.
