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 UK exec says EVs are a good way to lose a fortune

Stateside, Ford execs are quick to point out the automaker's expansion in the plug-in sector. And despite a minimal presence in the pure EV space, the Blue Oval has been promoting its plug-in vehicles as part of an overall effort to boost fleetwide fuel economy. Too bad the company's UK chief didn't get the memo. There's "no point in us getting behind [EVs] and losing a fortune" - Ford's Mark Ovenden Mark Ovenden, speaking rather frankly at the Geneva Motor Show recently, said he didn't have real high hopes for substantial electric-vehicle adoption and said the company's money was better spent on smaller gas- and diesel-powered engines, the UK's Daily Mail says. Ovenden said of EV development that there was "no point in us getting behind it and losing a fortune," adding that his goal was to have variants of Ford's EcoBoost engine in 40 percent of the company's vehicles. Ford has about a 15-percent market share in the UK. The UK doesn't appear to be as kind to the EV as the US. Nissan last year cut the price of its all-electric Leaf there last year by about $4,000, while the company rolled out a promotion for the Leaf late last year, including allowing Leaf drivers to borrow a gas- or diesel-powered Nissan for free for as long as two weeks a year during the first three years of Leaf ownership. In the US, Ford sold just 229 Ford Focus Electrics during the first two months of the year after moving 1,738 units in 2013.

TRANSLOGIC 147: CES 2014 Autonomous Vehicles

We head back to CES in Las Vegas to check on the progress of autonomous vehicles in 2014. We go hands-free on the highway with Audi, narrowly avoid a collision with Ford and hear all about BMW's drifting driverless car. But first we take a ride on Induct's self-driving Navia shuttle.
