Engineers and designers of the 2019 Silverado exterior implemented a host of improvements some owners will likely never even notice. But, it’s all for the greater good of refining the 2019 Silverado. One of those minor additions is the Gurney flap.
Also known as a wickerbill, a Gurney flap is a small tab that projects from the edge of a wing. It was made famous by famed racer Dan Gurney, who passed away this week. The simple addition helps improve aerodynamics, and in the case of the 2019 Silverado exterior, it contributed to a 7 percent improvement in the truck’s drag coefficient.
The 2019 Silverado exterior lends itself to a leaner full-size pickup truck. The truck is now 450 pounds lighter altogether, yet it also offers greater cargo capacity in the bed than before; the short box offers 63 cubic feet of volume.
