Defeating drag

With record-high fuel prices, increasing efficiency through aerodynamics takes on greater importance for pickups.

It has been well documented in recent months that automakers are looking to aerodynamics as a way to help meet the range targets for next-generation electric vehicles. For vehicles such as the Chevrolet Volt, aerodynamic improvement is essential for moving the vehicle to a final production decision. Not to be overlooked, however, is the work that has been done with the current generation of pickup trucks.

According to General Motors, aerodynamic drag accounts for 20% of the energy consumed in an average vehicle, having a direct impact on vehicle fuel efficiency. For pickup trucks, that number is most assuredly higher because of the excessive drag forces associated with the truck's bulky shape and cavernous bed.
