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.

2013 Ford Fusion Hybrid

Your Mileage May Vary
As difficult as it is to write this, I was actually excited about the 2013 Ford Fusion Hybrid. With the beautiful looks of the newest midsize fighter from Ford and a fuel economy estimate capable of shaming even the stalwart Camry Hybrid, the battery-augmented four-door seemed like a recipe for unabashed success. But appearances love nothing more than swapping our boundless enthusiasm for cold platters of disappointment. The 2013 Fusion Hybrid gets hobbled right out of the gate with a lofty price tag, and real-world driving keeps the sedan from even approaching those EPA figures.
With so many excellent midsize hybrids on the market, is there any reason to consider the newest Fusion Hybrid? Are sharp aesthetics, a well-executed interior and capable driving dynamics enough to overcome the machine's shortfalls? Not from where I'm standing.

Ford Ka Concept shown in Brazil, could enter production by 2014

The Ford Ka (pronounce it like a Bostonian saying "car") is the Blue Oval's sub-Fiesta offering in a number of markets that aren't North America. It's been a staple in Europe since it launched in 1996 and in South America since 1997, where it's enjoyed quite a bit of popularity as an affordable, efficient city car.
The European and South American models grew apart over the years, until Europe ended up with a Fiesta-inspired car and Brazil retained a more evolved version of the original Ka's styling. With this Ka Concept, which is really a concept in name only, Ford is previewing a Ka not just for the European market, but as the brand's new, global small car. With city car sales expected to grow dramatically in coming years and the ever increasing price of fuel, Ford's move to get a new, competitive car into the market on a global level isn't surprising.
Wearing Ford's new, familial grille, the Ka Concept features the same crisp, sculpted sheetmetal that's adorned the Fusion and Fiesta. Developed in-house by Ford Brazil, a production version could launch by 2014, according to Ford's press release. It's unclear what engines will sit under this car's hood, although we'd bet the 1.0-liter, EcoBoost three-cylinder from the Fiesta will be available at some point.
