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.

Ex-PR chief Vines accuses Ford of bugging cars, phones

Jason Vines, former head of communications at Ford among other automakers, is accusing the Blue Oval of bugging his company phone and his car during the Firestone tire recall for the Explorer in 2001. The allegations have come to light in Vines' upcoming book What Did Jesus Drive? Crisis PR in Cars, Computers and Christianity.
According to The Detroit News, which has an advance copy of the book, Vines (pictured above) claims that after leaving the company, someone with security within Ford advised him that he had been bugged around the time of the recall. The allegations don't stop there, though. Vines further contends that he might not have been the only one to get this treatment, noting that then-general counsel John Rintamaki also believed he was being listened to.
According to The Detroit News, even if it had been a company phone, recording Vines without his knowledge still would have been a felony under Michigan law.

Hennessey unleashes 2015 HPE700 supercharged Ford Mustang

Thanks to the 2015 Dodge Challenger SRT Hellcat there is a new magic number in the muscle car world - 707. To raise eyebrows these days in the power war, a vehicle needs to match or preferably exceed that palindromic figure. The tuners over at Hennessey took a look at it for their 2015 HPE700 Mustang and decided to go one better. Well, ten actually, because they bestowed their latest creation with 717 horsepower and 632 pound-feet of torque.
The HPE 700 Mustang takes the standard Mustang GT with its 5.0-liter V8 and turns up the power a few hundred notches with a Roots-type supercharger running at 7.25 psi. Hennessey claims that this boosted 'Stang can rocket to 60 miles per hour in about 3.6 seconds and cover the quarter-mile in 11.2 seconds at 131 mph. For those keeping score at home, those figures are very similar to Challenger Hellcat.
To cope with all of the added boost, the engine gets a high-flow throttle body, upgraded injectors, new fuel pump, stainless steel exhaust and Hennessey's calibration for the engine management. Pricing for the package is $59,500, including the base 2015 Mustang GT, but the company is limiting production to 500 units for the 2015 model year. Founder John Hennessey told Autoblog that he has already received about a dozen orders for them.
