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 EcoBoost smashes records at Daytona

Some mighty machines have lapped the banks of the Daytona International Speedway over the years: thunderous V8-powered stock cars, Le Mans-conquering Group C prototypes, open-wheel Champ Cars, knee-dragging superbikes... heck, the infield lake has even hosted powerboat racing. But this - this is the fastest car ever to lap the legendary raceway.
What you're looking at is the new Daytona Prototype being prepared by Riley Technologies for the new United SportsCar Championship. The car, released just last week, is powered by a new 3.5-liter turbocharged V6 from Ford's EcoBoost family, and just obliterated the top speed at the track with a blistering 222.971 miles per hour through the traps.
That's enough to annihilate the previous record that was set, also under Ford power, by Bill Elliott while placing his Thunderbird on pole for the 1987 Daytona 500 that he would go on to win. His 210.364 mph record had stood for 26 years until now.

Hyundai, BMW and Ford win Concept Vehicle of the Year awards

More than two dozen jurors started with a pool of 23 concept cars introduced at the most recent Los Angeles, Detroit, Chicago, Toronto and New York auto shows, then pared it down to three winners in three categories for the twelfth annual North American Concept Vehicle of the Year Awards. The trophy-bearers are said to be those "vehicles most likely to shape the future of the automobile industry," and lead their classes in the Concept Car, Concept Truck and Production Preview divisions.
Hyundai had two cars as finalists for the Concept Car category, the competition boiled down to the Hyundai HCD-14 Genesis concept, Veloster C3 Roll Top, Honda EV-STER and the Toyota Corolla Furia. It won with the HCD-14 Genesis that was introduced at the Detroit Auto Show, a sharp sedan that sharply divided opinion between those who thought it was too much, those who thought it was too much Audi A7, and those who thought it was perfect. The award panel's judges, however, thought so much of it that it's got two awards in one sitting, not only taking concept car honors, but because it earned the highest overall score in the competition it also takes the crown for Most Significant Concept Vehicle of 2013.
The final selection in the Concept Truck category was down to the Ford Atlas, Kia Cross GT, Nissan Resonance and Volkswagen Cross Blue. The Ford Atlas took the silverware, after also winning the Eyes on Design award - shared with the Nissan Resonance - at the Detroit Auto Show where it was introduced.
