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.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

Peel and Ford Transit do a great Austin Powers impression

It's no secret that the average fullsize cargo van is big. Like, really big. Expressing that size, though, without actually seeing the van in question, is a pretty tall order. When viewed from the right angle, even something as big as a cargo van can appear very small (look up forced perspective, to see what we mean). That's why it's always good to have a second object on hand, to provide a sense of scale. Ford took this simple idea to the extreme, illustrating the size of the new Ford Transit by pulling the world's smallest production car, the Peel P50, nose first into the van's 487-cubic-foot cargo area. That's no big deal, though, right? After all, at just 54 inches long and 39 inches wide, the Peel would fit quite happily in even the smallest fullsize truck bed. Ford takes it a step further, though. With the help of an actual reverse gear (we're guessing this is a CVT-equipped, electric model), the P50 manages to turn itself around and drive out. It does this in less than two minutes. So yeah, the Ford Transit is a pretty big van. Take a look below for the video from Ford. This content is hosted by a third party.
