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.

Auto critic calls out Corvette, Mustang and Cherokee faithful

Most automotive purists fear change, but not without reason. Change, after all, did kill big-block V8s, along with most station wagons and manual transmissions. But change has also brought with it far more performance, safety and fuel economy - not to mention ridding the world of shag carpet interiors, bias-ply tires and those horrible motorized seatbelts of the early '90s.
By this time next year, the Chevy Corvette, Jeep Cherokee and next-generation Ford Mustang will all be on sale and will all, in some way, have angered or offended purists. To those critics, Mark Phelan of the Detroit Free Press is preemptively telling them to stop complaining - at least until they've all been driven. From the Corvette's square taillights and the Cherokee's radical nose to whatever pony car purists will harp on the 2015 Mustang for, Phelan's column points out the positives of automotive evolution and the negatives of staying the course for too long. That's fair enough, but do you think Phelan is on point, or all wet? Head on over to the Detroit Free Press to read his words, then have your say in Comments.

Ford celebrates 1 millionth Mustang built at Flat Rock

Yesterday, the Ford Mustang turned 49 years old, and Ford didn't miss the opportunity to celebrate the one millionth version of the Mustang rolling off the assembly line at the Flat Rock Assembly plant. Production of the Mustang at Flat Rock coincided with the fifth-generation design launching in 2004, and the one millionth car was the car shown above, a 2014 GT convertible painted in Ruby Red.
In total, Ford has sold more than 8.5 million Mustangs since the original car went on sale, but some of the key milestones over the car's nine years at Flat Rock include the Shelby GT-H, Bullitt, Boss 302 and, of course, the 662-horsepower Shelby GT500. Scroll down for a press release celebrating Flat Rock's milestone Mustang.
