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.

Roush getting back into sport compact business with Focus ST mods [w/video]

Roush Performance offers a whole raft of parts for folks looking to tune their Ford Mustang and F-150 models, and now Focus owners can start getting in on the hotted-up action, too. Owners of the 2012-13 Focus and 2013 Focus ST can now get a Roush cold-air intake system, and ST owners can also opt for a high-performance cat-back exhaust.
Although all of these components are now available for order, the parts will ship sometime in July; no word yet on pricing. Down the road, Roush will also offer styling upgrades for the Focus as well as performance tuning upgrades such as engine controller, suspension, wheels and tires. Scroll down for a quick video of what the Focus ST exhaust sounds like, as well as a Roush press release.

eBay Find of the Day: 1970 Ford Torino King Cobra prototype

Over the last decade or so, competition in NASCAR has led to some pretty funky looking racecars. And when the sport was still up and coming, the tight competition actually led to some interesting production cars. The Dodge Charger Daytona and Plymouth Superbird are perhaps the most well-known cars of the sport's "aero wars" era but the Ford Torino King Cobra might have been the most memorable of all, if not for some different homologation rules established in 1970. The Torino King Cobra never made it to production and never competed in NASCAR, but three examples exist including this one now for sale on eBay.
Designed as a successor for the aero-tuned Torino Talladega, the Torino King Cobra has a sleeker front end with hidden headlights and a sloped nose. As the story goes, NASCAR made a rule change in 1970 requiring 3,000 of the vehicles to be produced, which was substantially more than the 500 units required by the previous rule. One of the three prototypes ever built - and the only one built with the Boss 429 engine - is now for sale on eBay with a starting bid of $500,000. With a little more than three days left on the auction there are still no bids, but in the grand scheme of things this seems like a relatively fair price for a rare piece of automobile and racing history.
