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 spider screen keeps creepy-crawlies out of cars

Ford is waging a global war on spiders with the 2016 Focus RS. The little beasties can be a real menace to a vehicle by blocking lines with their dense webs, but engineers at the Blue Oval now have a new screen that they claim keeps the bugs at bay. Yellow sac spiders especially like to craft their webs in fuel vapor lines, but blocking the way can cause pressure to build, leading to a safety issue. Implemented in 2004, Ford already has a screen to keep the creepy-crawlies out. But the company now has an updated version in North America, and the Focus RS is the first global vehicle with it. "We are constantly improving and adapting, even when it comes to technologies that are already working," said William Euliss, Ford fuel systems engineer, in the screen's announcement. It might seem like a waste to put engineers on the task of making a spider screen, but the device could save Ford money in the long run. Arachnids have been responsible for the recalls of hundreds thousands of vehicles in the US over the years. Mazda issued two campaigns on the Mazda6 due to the webs causing pressure to build up in the fuel tank and potentially leading to a split. There was also a similar recall from Suzuki, and another one covering the air conditioning system on Toyotas. LOOK OUT! HERE COME THE SPIDERMEN: FORD ENGINEERS USE ARACHNID LEARNINGS TO DEVELOP INNOVATIVE SCREEN TO KEEP CREEPY CRAWLERS OUT AUG 5, 2015 | DEARBORN, MICH. Ford engineers developed an innovative spider screen to keep the creepy crawlers from nesting inside vehicles Screen prevents spiders from building cocoon-like webs dense enough to potentially block fuel vapor lines, which can damage engines and diminish vehicle performance Now, an updated version of the spider screen is being implemented in Ford vehicles in North America; it will go global with launch of the all-new 2016 Ford Focus RS DEARBORN, Mich., Aug. 5, 2015 – Arachnophobes may not know this, but there is a team of Ford engineers who developed an innovative spider screen to keep the creepy crawlers from nesting in Ford vehicles. You're welcome. Cheiracanthium mildei and Cheiracanthium inclusum – more commonly referred to as yellow sac spiders – have been known to nest inside vehicles in North America, causing problems for car owners and automakers alike over the years. Instead of using webs to catch prey, these spiders build cocoon-like webs for shelter and to lay eggs.
