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

Thanks to the smoke wand in the wind tunnel, you can actually see the difference in our video.
Should you drive with your pickup truck's tailgate up or down? It's an age-old controversy that's divided drivers for decades. Traditionalists will swear you should leave the tailgate down. Makes sense, right? It would seem to let the air flow more cleanly over the body and through the bed. But there's also a school of thought that argues trucks are designed to look and operate in a specific manner, and modern design techniques can help channel the airflow properly. So don't mess with all of that: Leave the tailgate up.

Watch this Ford F-150 SVT Raptor fly like an eagle [UPDATE]

The Ford F-150 SVT Raptor is a very capable truck right out of the box, but "capable" has never translated into "invincible." Just ask the owner of the machine in this video. In it, the driver gets frisky with an aggressive jump with plenty of speed on his hands. The result is enough air to make Vaughn Gittin Jr. blush. As always, it's not the launch that's painful, but the re-entry. Gravity eventually asserts its dominance over the $43,630 pickup in a big way, and when it comes crashing down, it does so with a vengeance.
The impact was hard enough to set off both the alarm and multiple airbags inside the cabin. It's unclear if anyone was injured in the stunt, but we certainly wouldn't be surprised to hear that was the case. You can check out the stunt in the video below, and remember, when in doubt, back out of the throttle. Be warned, there may be some explicit/NSFW language in the clip.
UPDATE: Second video added with an even better look at the jump added below.

Ring Brothers shows 1965-66 Mustang fastback carbon fiber body

We covered one of Ring Brothers' more extreme SEMA builds yesterday, the De Tomaso Pantera-based ADRNLN, but if that well-executed but over-the-top Italian-American exotic is too much for you, then perhaps this Ring Brothers 1965 Ford Mustang fastback with a carbon-fiber body suits your tastes better.
What the performance-parts manufacturer is showcasing with the Mustang is the carbon-fiber body itself, which is fashioned around the 1965-66 fastback. It can be bought from the company and bonded to the skin and unibody as a do-it-yourself project, or you can take your Mustang to Ring Brothers and have the body installed there. The fenders, doors and quarter panels are two-inches wider than stock, and Ring Brothers offers a custom widebody chassis to those who want the complete package.
The show car looks sharp in person lowered on HRE wheels, and we appreciate the bare front end so we can see the supercharged V8 and front coilover suspension, though the details on those performance upgrades are slim. Also note the custom independent rear suspension setup at the rear.
