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.

Shelby American cleans house of 14 concept cars

Typically when an automaker rolls out a concept car or pre-production prototype, it does its tour and then disappears into the company's archives. Maybe it will be displayed for the public to see in the company's own museum or maybe it will spend most of its time under covers in a warehouse somewhere, but every once in a while, an automaker will open up its history and start selling off its concept cars. For Shelby American, "once in a while" has just rolled around.
The House that Carroll Built is moving from its previous headquarters at Las Vegas Motor Speedway to a new facility off of the Las Vegas strip, and in the process is liquidating fourteen of the rarest cars in its collection. That presents a tremendous opportunity for muscle car collectors to bring one or more of these snakes home.
As you might expect, the catalog is composed mostly of Mustangs, but not exclusively. There's a pair of 289 Cobras: the last of the 50th anniversary slab-sided continuation cars and an original development vehicle, offered at $200,000 apiece. At the other end of the spectrum you'll find the 2013 Shelby Raptor concept for $125k and Focus concept for $50k. And of course there are the Mustangs.

Ford EcoSport Storm concept swallows a Raptor in Sao Paulo

Ford rolled into the Sao Paulo Motor Show with some pretty cool crossovers in tow, the awesomest of all being the EcoSport Storm concept shown above, which draws its inspiration directly from the F-150 SVT Raptor. It packs a lower grille clearly derived from the now-famous muscle truck, as well as a Blue Storm paint job, black and silver trim, special graphics, lower body cladding and 215/75 R15 off-road tires. Don't go holding your breath for a supercharged V8, though; made locally in Brazil, India and Thailand, the tiny EcoSport is typically powered by a three- or four-cylinder engine.
The Storm isn't the only specially prepared Ecosport on show, however, joined as it is by another pair called Beauty and the Beast. Beauty is decked out in matte copper with a black roof, LED fog lamps, 18-inch wheels with low-profile tires and an interior complete with four individual bucket seats, leather upholstery and a full multimedia suite. The Beast, meanwhile, takes a sportier approach with a white pearl finish, blue and orange trim and three-bar grille. It also wears 18-inch wheels and LED fog lamps, but its interior swaps out its rear seats for a bike rack.
Joining the EcoSport show cars was an Edge crossover equipped with all the latest technologies and done up in bright red with three-bar grille, bulging hood, and an interior featuring 10-inch touchscreens and leather upholstery. Feel free to read more in the press release below.
