MONEY FROM THIN AIR

摘要

Adding aerodynamic devices to smooth airflow over the vehicle at highway speeds is a (relatively) cheap and easy way for fleets to improve fuel economy in long-haul tractor-trailer applications. But calculating fuel savings and return on investment for aerodynamics can be notoriously tricky. Moreover, not every aerodynamic device on the market today is appropriate for all applications. Luckily, several recent, high-profile studies have made it easier for fleet managers to identify the best devices for their applications and to determine both fuel savings and a realistic ROI timeline.
