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.
Take a look below, and let us know what you think in Comments.

Expert: 54.5 mpg CAFE standard can be reached without many plug-ins

Johnson Controls executive Brian Kesseler isn't likely to get any holiday presents this year from Nissan chief Carlos Ghosn or Tesla Motors head Elon Musk, but lots of other folks might be happy with what he has to say about automakers' efforts to reach stricter fleetwide fuel-economy standards. Speaking at the Automotive News World Congress, Kesseler said automakers wouldn't need to sell an extensive number of plug-in vehicles in order to meet the 54.5 mile per gallon Corporate Average Fuel Economy (CAFE) standard the US government set in 2012 for 2025 model-year vehicles. In fact, he said, components such as stop-start engine technology, turbochargers and direct injection may actually do the trick. Already, things like smaller engine sizes and lighter cars are already playing major roles in spurring fuel-efficiency gains. Of course, Johnson Controls sells batteries specially built for stop-start systems, so Kesseler does have a bit of skin in this game. The 54.5-mpg CAFE standard equates to about a 40-mpg "real world" fuel-efficiency level. To put that into perspective, the Environmental Protection Agency (EPA) said in a report late last year that model-year 2013 average fuel economy was an even 24 mpg. That was up from 23.6 mpg for the 2012 model year and 22.4 mpg for 2011.

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.
