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.

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.

Ford bringing C-Max Solar Energi Concept to CES

Solar energy might not be enough to power a usable electric vehicle on its own, but that doesn't mean it can't lend a helping hand. And that's what Ford has in store for the Consumer Electronics Show opening next week in Las Vegas.
Ford has essentially taken its C-Max Energi plug-in hybrid and fitted it with the latest in solar panel technology developed by SunPower, acting like a magnifying glass to capture as much of the sun's energy as possible. So you get the benefit of an electric vehicle, with the range assurance of a hybrid, without needing to draw from the grid.
Ford estimates that a day of charging in the sunshine will give the C-Max Solar Energi concept the same full charge as the production PHEV, with a total range of 620 miles - 21 of which can be run on electric power alone. Otherwise the vehicle - which remains a concept for the time being - is identical to the existing C-Max Energi. The top-selling model in Ford's growing hybrid and electric vehicle portfolio helps put Ford just behind Toyota among the top seller of hybrids in America. Scope out the images in the gallery above and the video clip and press release below for a closer look.
