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 updates Power Stroke diesel V8, strengthens F-450, tweaks King Ranch

Ford is giving its F-Series Super Duty trucks some upgrades for 2015, and we're happy to say that one of them is an improved Power Stroke diesel V8. Also, Ford is strengthening the top-of-the-line F-450 to handle more abuse. And if wild west-style luxury is your thing, the automaker has performed minor cosmetic updates to its King Ranch Edition trucks, as well.
The turbocharged 6.7-liter Power Stroke V8 is currently rated at 400 horsepower and 800 pound-feet of torque, and Ford only tells us the new and improved Power Stroke can "produce power beyond today's" engine. What, then, did Ford actually improve upon? First, the Blue Oval swapped in a new, larger turbocharger. The new Garrett GT37 turbine unit is 72.5 millimeters in diameter, eclipsing the old GT32's 64-mm diameter piece. Ford states output increases with the new turbo setup, but since the new turbocharger operates at a lower peak pressure than the old one, the automaker was able to eliminate the wastegate system and reduce the engine's complexity. Ford even redesigned the turbo's oil and cooling lines to make the powerplant simpler. A byproduct of the larger turbo is better engine exhaust braking, which is controlled manually by a button on the dashboard.
Ford claims the upgraded diesel engine is more powerful, more robust, more efficient and more refined than before.

Americans will get a four-cylinder Ford Mustang after all? [w/poll]

Ask and you shall receive. Remember that previous report suggesting that the 2015 Ford Mustang getting a four-cylinder EcoBoost engine, and that it would be sold in Europe only and not the United States? Well, according to Road & Track, the rumor is only partially true - The Mustang will get the engine, but it is indeed coming to America.
Additionally, according to RT, the 3.7-liter V6 will continue to serve as the base engine, and since it offers up a stout 305 horsepower in its current form, it's likely that the 2.3-liter four-cylinder EcoBoost will produce a bit more than that. At the top of the range, the Mustang GT will continue to soldier on with a V8 engine, which should continue to send over 400 horsepower to the rear wheels.
Finally, while we agree 100 percent with RT's heartfelt request for a paddle-shift automatic, we certainly expect that the EcoBoost 'Stang will be offered with a manual transmission as standard equipment. This is a Mustang, after all...
