How Ford secretly used customers to test its aluminum F-150 [w/video]

Automakers getting clever about disguising development vehicles isn't anything new. Between mules wearing the sheetmetal of other cars and prototypes decked out in as much camouflage as is practical, automakers know how to make it very difficult for the general public to get an exact idea of what kind of vehicle is in development. Ford, though, is rapidly becoming the master.
We knew that the Blue Oval originally tested the durability of the aluminum construction being used for the 2015 F-150 by building an all-aluminum 2014 truck and entering it in the Baja 1000 off-road race. That's no longer a secret. What we didn't know, though, is that the aluminum development dates back to before even that, and that some of the people in question had no idea what it was they were working with.
Ford says this is the first time prototypes have ever been handed over to the public.

And the Top Gear UK Cars of the Year for 2013 are...

Those loony Brits at Top Gear have named their Car of the Year, and if you're thinking it's the McLaren P1, Jaguar F-Type, Land Rover Range Rover Sport or Rolls-Royce Wraith, we're sorry to inform you that none of those Anglo automobiles earned the crown. In fact, the winner of Top Gear's most prestigious award is quite the surprise.
Of course, those cars weren't without their own awards. The P1 was the top hypercar (sorry, Porsche 918 and Ferrari LaFerrari), while the F-Type netted best convertible and the Range Rover Sport was voted SUV of the Year. Other honorable mentions included the Mercedes-Benz SLS AMG Black and S-Class, the Porsche 911 GT3, the BMW i3 and the Ferrari 458 Speciale. The winner, though, wasn't even a high-dollar supercar. It was the Ford Fiesta ST.
Yes, the Fiesta ST beat out some off-the-wall cars like the revolutionary Volkswagen XL1 and the bonkers Peugeot 208 T16 Pikes Peak, not to mention all the cars we listed above, to take the title of Top Gear Car of the Year. And if you've driven one, you'll completely understand why.

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.
