Which is more fuel efficient, driving with a pickup's tailgate up or down?

Another interesting read and video.

To solve this tailgate debate, we went inside the wind tunnel at Ford to test the aerodynamics of the 2015 Ford F-150.

Which is more fuel efficient, driving with a pickup's tailgate up or down?

Cool find Donna. Now I'd love to see how it looks towing all our various Escapes!

Thank you! Been wondering the answer since I was a kid and my friend took off his tailgate to go faster .... he just lost things out the back.

Off topic: Earlier today I was wondering what the purpose of the pad is that you see draped over the tailgate of some pickups.

Great link, Donna. I had heard of similar finding, but it is nice to watch that video for proof.

They are usually for carrying bikes in the back, where the box is too short for them to fit inside.

They are also used for surfboards, paddle boards, etc.

Well, who am I to argue with engineers with their own wind tunnel

But I really don't believe that demo is an apples and apples comparison.

Not to belabor my lack of knowledge but that demo is a static display of smoke flow. A true test would measure dynamic drag and I don't believe for a second that there's less drag with the tailgate up. Also they don't show the smoke flow, from the front, with the tailgate down.

Are the claims real or is it a tightly scripted marketing plan to sell the new design of the tail gate? I'm a hard sell.

I'm a hard sell too. But, Myth busters did a segment on this very topic some time ago, and they also got better mileage with the tailgate up. They explain why at the link:

It's one of those things that defies logic, but it's good for all of us with trucks that our stuff doesn't slide out the back while getting better mileage.
