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 C-Max Solar Energi takes a recharging station wherever it goes

Companies ranging in size from small startups to major automakers have been experimenting with solar-powered charging stations for EVs and plug-in hybrids. And, of course, people have been powering vehicles with onboard solar panels for quite some time, too. Still, Ford's new C-Max Solar Energi Concept shows the promise of a truly practical implementation of solar on a production vehicle, and it may not be as far off in the future as we had thought.
As we reported a few days ago, the Solar concept makes use of a "concentrator lens" that focuses sunlight onto the Ford's roof-mounted solar panels. The special lens follows the rays of the sun to maximize the amount of charge being fed to the batteries of the car, taking about a day to fully charge the 21-mile, all-electric range of the C-Max Energi. Ford data suggests that combination might be enough to power 75 percent of all trips made by a statistically average driver. In turn, using the sun to power a vehicle could reduce yearly C02 emissions by up to four metric tons when compared with the driver of an average gasoline-powered sedan.
We've got live images of the C-Max Solar Energi Concept, jauntily tilted on its display to best present it's signature solar panels, straight from the CES floor.

Ford shares falling on news of lower-than-expected profits next year

Ford has released projections for its 2013 profits, along with predictions of its 2014 earnings, and the news has forced the company's stock to stumble, falling over seven percent as of this writing. The Blue Oval is expecting earnings of $8.34 billion for 2013, although the bulk of that is coming largely from its North American operations, as troubles abroad continue to take a toll.
Calling 2013 an "outstanding" year, Ford expects its revenue to be up about 10 percent, thanks to gains in market share everywhere but Europe. But it's 2014 predictions that are causing stock prices to fall, as the Dearborn-based manufacturer expects pre-tax profits to fall to $7 to $8 billion, because of troubles in both Europe and South America, according to a report from Reuters. This is despite an expansion plan that will see it open an additional factory in the southern hemisphere, as well as two plants in China, all in a bid to launch 23 new or refreshed products next year.
The issues in South America aren't so much related to a fall in sales - Ford expects improved profits in Brazil and Argentina - but because of currency devaluations in Venezuela that are projected to cost it around $350 million. While that would still allow it to break even with 2013, Ford cites continued economic risks that could push losses even higher.
