Today’s tip will probably come as a surprise to most of you, but will be especially useful for those of you who drive trucks.
Driving with your tailgate down doesn’t help you save gas.
I’ll be the first to admit, I bought into the notion that by having your truck’s tailgate down while you’re driving down the road (especially the highway) you would greatly increase your truck’s fuel economy. Apparently that just isn’t true.
According to several sites (Ask Yahoo! for example) state that you get roughly the same gas mileage driving with your tailgate up as you do when your tailgate is down.
According to the Ask Yahoo! article, this is the reason why:
“When the tailgate is raised, a “separated bubble” of stagnant air is formed in the bed of the pickup. Wind tends to swoosh over this bubble as though it were part of the truck. Lower the tailgate, and the bubble disappears, which leads to increased wind resistance.”
So, get rid of that net you used to replace your tailgate and go ahead and drive around with your tailgate up!
