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.

Watch a Ford Bronco casually jump a McLaren 720S

Michael Cox can't stop jumping his classic Ford Bronco. He's jumped it on the beach. He's jumped it in the desert. He's jumped it at racetracks. Now he's jumped it in Hoonigan's backyard playground. Upping the ante on this one, he completed the jump while a modded McLaren 720S drifted underneath.  For those who don't know Michael Cox, he's a builder, racer, mad man extraordinaire who's worked with BMW and Porsche and specializes in off-road racing. Possibly more famous than the man is the vehicle he's known for driving, a custom-built Bronco that sports a cat-themed desert camo wrap.  Technically, this is not the first time Cox has visited Hoonigan and jumped his Bronco. But last time, the Bronco soared over nothing but tire crumbs and those tiny pebbles that get stuck in tread. This time, the stakes grew significantly, as a custom 720S drifted under the Bronco while it was in the air.  After a few donuts, Cox first tries a jump over a flatbed trailer. Once he easily clears that obstacle, Hoonigan brings the McLaren into the picture. Watch the video above to see a few crazy men show total disregard for the cost of a supercar.  This content is hosted by a third party. To view it, please update your privacy preferences.

A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.
