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 previews updated Police Interceptor Utility for Chicago debut

With more law enforcement agencies across the United States alone than we'd care to count (or ever encounter), selling police cars means big business for American automakers, with Ford, Chevy and Dodge competing to fill the motorpools of every police department, sheriff's office and government agency in the land. For its part, Ford offers the Taurus-based Police Interceptor sedan and the Explorer-based Police Interceptor Utility, and it's preparing to unveil a revised version of the latter at the upcoming Chicago Auto Show in the same city where it's built. Dearborn hasn't given us much to go on with this teaser, showing just a darkened front shot of the vehicle in question with its emergency lighting all aglow. But it's fairly clear that the Interceptor Utility has been given many of the same updates applied recently to the Explorer on which it's based. That starts with the revised sheet metal, but considering that the Interceptor Utility exclusively packs V6 power, the 2.3-liter EcoBoost four that was one of the biggest updates to the civilian Explorer isn't likely to carry over. Ford does, however, promise that the revised Police Interceptor Utility will be "even better" than the model it replaces" and pack "more high-tech features." Related Video:

2015 Ford Mustang stars in bizarrely awesome '80s aerobics video

For reasons we can't comprehend, here's a music video starring the all-new, 2015 Ford Mustang and a number of dancers dressed and styled in the most stereotypically 1980s way possible. The dancers then take part in a male-versus-female dance off. Again, we've no idea why it exists.
It's weird, and for the second time in two weeks, we're sat at our computer wondering, "What are we watching?" That said, it does show the new Mustang from a number of angles, and it's one of the first car-related YouTube videos we've seen that's available in a 4K, ultra-high-def stream.
