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 Escort testing, may be bound for Europe

There has been little news about Ford's China-focused Escort concept since debuting at last year's Shanghai Motor Show, but the no-frills sedan has shown its camouflaged face again during cold weather testing in Northern Sweden. While far from a guarantee, the test location might hint that the Blue Oval plans to market the car outside of Asia.
The Escort's black robe and zebra paint make it hard to tell if anything specific has changed about the design, but the shape of the sedan looks close to what was shown in Shanghai. Under the disguise, you can still make out the hexagonal front grille from the concept. When Ford announced the model, the company said that the design wasn't supposed to be "arrogant or pretentious," and it certainly achieved that. The engine range is still a mystery, but it seems safe to expect small, economy-focused powertrains.
A report from last year indicated that Ford may be considering broadening the new Escort beyond Asia and possibly even selling it in Europe. The fact that the company brought it to Sweden for testing could bolster that argument. A release date hasn't been set yet, but the automaker has promised 15 new products for China by 2015. The basic sedan could be on the road soon.

BMW to follow Honda back into F1?

The economic downturn wrought devastating effects on motor racing. Formula One alone lost half its engine suppliers when Honda left at the end of the 2008 season, and both BMW and Toyota followed at the end of 2009. But things are looking up again. Cosworth may have dropped out this season, reducing the engine suppliers to three: Ferrari, Renault and Mercedes, the latter of which admits that it may have left had the engine formula not changed. But Mercedes has stayed and is dominating the championship. Honda is coming back next season. And word around the paddock is it may not be the only one.
According to Giancarlo Minardi - founder of the team now known as Scuderia Toro Rosso - BMW engineers have been conspicuously spotted lately at F1 test sessions and grands prix, lending to speculation that the new engine regulations may entice the Bavarian automaker back into the series. According to Minardi, BMW's marketing division is pushing for the automaker's return to F1, with the board slated to make a decision in May. BMW would be more likely to consider an engine-supply deal rather than taking a team over like it had with Sauber, but with which team or teams it might collaborate remains a big question mark at this point.
As if that's not enough, Ford is said to be considering taking over Cosworth's aborted V6 turbo engine program to take both outfits back into the sport as well. Cosworth supplied F1 engines under the Ford banner for years, but returned under its own name for four seasons from 2010 through 2013 before shuttering its program to develop an engine to meet the new regulations adopted this season.
