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.

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

Focus STs for SEMA include Lotus and Gulf liveries, rally-fied police car

Ford, as we mentioned on Saturday, is pulling out all the stops for November's SEMA show, bringing 57 vehicles to the Las Vegas event. Ford will be staggering the release of its SEMA flotilla, though, so expect to hear a lot about the new additions to the fleet in the weeks to come. We already showed you the Fiesta, Fiesta ST and Mustang models that made up the first batch of SEMA cars. Next up, we have a quartet of modded Focus STs joining Ford's SEMA roster.
Our first Focus ST (pictured above) sports the legendary livery of Gulf Racing. The orange-on-blue scheme, which Ford helped make famous at the 24 Hours of Le Mans, has been updated for 2013, with a more vibrant blue. This ST was built by Universal Technical Institute, while the exterior was done by Neil Tjin of Tjin Edition. Side exhausts, a Vortech supercharger and a Motiv Concepts high-flow cat allow the ST to breathe a bit easier, while Forgestar wheels contrast well with the iconic paint scheme.
Focus ST number two has been done-up by PM Lifestyle and is inspired by "Southern California car culture." Sporting a sleek, pale blue paint job, there's also no shortage of carbon fiber on the car's exterior. The 2.0-liter, turbocharged, four-cylinder engine has been massaged by the likes of Banks Power, COBB Tuning and Ford Racing, while the suspension is wearing a shiny, new set of coilovers and sway bars. The meaty brakes, tucked behind 19-inch, Rotiform wheels, come from Wilwood, while the cabin has been fitted with a pair of Sparco Chrono seats and five-point, Schroth harnesses.
