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.

Ford, Ram in heavy-duty towing spat

Every pickup truck commercial has the brand trying to convince us that its model is the biggest, brawniest vehicle on the block. But Ford and Ram appear ready to really throw down the gauntlet and scrap over the towing figures for their heavy-duty models, and it could potentially end up in court.
The issue revolves around what it means to be best in class. Ford claims that its 2015 F-450 (pictured above) has a max tow rating of 31,200 pounds, compared to 30,000 pounds for the Ram 3500 (right). However, both companies market these heavy haulers as having the top towing in their class. According to Automotive News, Ford is threatening legal action if Ram doesn't back down.
The situation isn't as simple as just comparing the numbers, though. First, the two companies calculate their towing capacities differently. Ram adheres to the SAE J2807 rating, while Ford uses its own internal system. Although, as the company introduces new models, they are certified using the SAE standard. "When an all-new F-Series Super Duty is introduced, it also will use SAE J2807," said Ford to Autoblog in an emailed statement.

Exceptionally rare '65 Ford GT40 Roadster prototype up for auction

Think of mid-engined supercars and your mind is bound to gravitate towards Europe, but the United States has been known to make a handful from time to time - exceptional vehicles from the likes of Vector, SSC, Mosler, Hennessey, and Saleen. But long before any of those came around, Ford famously became obsessed with beating Ferrari at its own game, leading to the development of the iconic GT40.
The story is well known, sending Ford to the checkered flag at Le Mans four times in a row in the late 1960s. Ford and Shelby also built over 100 for public consumption, but just four of them were roadsters. Of those only one remains in original condition, and now that exceedingly rare example going up for auction.
Consigned to RM Auctions for its mid-August sale during Pebble Beach weekend in Monterey, California, this 1965 model is the first GT40 Roadster built. It was used as a development and demonstration vehicle for Ford and Shelby. Carroll Shelby himself drove Henry Ford II in this very car during one of many test and demo events, this time held for Ford's board of directors in Los Angeles.
