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.

2018 Ford Expedition spied looking stylish

The Ford Expedition and Lincoln Navigator got a cool reception for their 2015 warmed-over redesign. But with big, high-riding vehicles once again in vogue, Ford is pushing ahead with a ground-up redesign of its biggest SUVs. Based on these spy shots, the Expedition will continue to serve as the Navigator's more affordable twin. Yes, that's a bold prediction, considering we still haven't spotted Lincoln testing the new Navigator, but study the greenhouses on this Expedition prototype and the Navigator Concept from New York – from the arrow-straight belt line to the extra-long rear window to the aggressively raked windshield, this Expedition's overall profile is broadly similar to what Lincoln previewed earlier this year. While our spies claim the new Expedition will look to the F-150 for design inspiration, we see a departure from past Expedition tradition. Unlike the supposed Expedition spy shots we showed you nearly a year ago – which was nothing more than an SUV with an F-150's nose grafted on, this prototype's front-end styling looks softer and more aerodynamic, with a smaller grille and headlights, almost like an Escape or Edge. This kind of change would explain the additional front-end camouflage. In back, our spies rightly point out that Ford fitted a faux rear end to disguise the rear window's rake – expect the real thing to feature the angled rear window previewed on the Navigator Concept. Look at the last image in the gallery for a better idea of how the Expedition's rear window will actually look. We can't say a lot about the taillights, because of the camo, but non-LED taillights are present. We'd expect Ford to offer LEDs on higher trim levels. While the F-150's styling might not make the transition to the Expedition, its powertrains and emphasis on lightweight aluminum will. Our spies report the biggest SUV will ride on a new T3 platform and feature an aluminum body, with the F-150's 3.5-liter EcoBoost V6. Expect a ten-speed automatic transmission and start/stop tech for sure, while the smaller 2.7-liter, twin-turbo V6 could slot in as the Expedition's base engine – we're less sure on that one. And we're even more uncertain of the rumors of an Expedition Hybrid. Our spies report it could mate a 3.5-liter V6 with an electric motor(s) and battery packs for a more economical full-size SUV. Expect to see the 2018 Expedition debut in January, at the 2017 Detroit Auto Show.

Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.
