Ford F-150 Tremor to pace NASCAR Truck Series this weekend

Ford's bro-tastic F-150 Tremor will be pacing this weekend's NASCAR Camping World Truck Series at Michigan International Speedway. The Tremor fills a gap in the Ford F-Series lineup that we imagine the NASCAR set have clamored for - a hot-rod pickup truck.
Where the F-150 Raptor is designed to go quick on anything, the Tremor and its 3.5-liter EcoBoost V6 are designed to tackle the road. The 365-horsepower and 420-pound-foot EcoBoost is unchanged from the rest of the F-150 line, but it combines the shortest drive ratio with the lightest two-door body, making it a bit of hot rod.
Ford will be offering hot laps with Michigan native Brad Keselowski behind the wheel of the Tremor for fans that arrive in the Irish Hills on August 14. The main showing for the new pickup will be the August 17 race, though, when it'll lead the field at the start of the race and through cautions.

Chevy Silverado frame twist test a marketing victory versus Ford

The pickup market is so competitive that all three major American makers are constantly trying to find a way to prove their product is the best. The new 2015 Ford F-150 is grabbing headlines at the moment by winning awards and posting segment best numbers. But in a new video, Chevrolet is taking aim squarely at the 2015 F-250 Super Duty in a battle of heavy-duty truck supremacy against the 2015 Chevy Silverado 2500HD... well, in a single metric anyway.
The big numbers from pickups often come down to payload, towing rating and fuel economy, but for this test, Chevy and Howie Long are challenging the torsional rigidity of the trucks' frames, specifically which one flexes less. Long plays the everyman here having the Chevy engineer explain what's going on in the tests. Unsurprisingly for a video on Chevy's official YouTube page, the 2500HD wins out by a good margin. The company also reports that similar results as shown here have been certified in third-party testing.
Check out the video to see the full test. While this might seem like a marketing win for Chevy, Ford isn't immune to it, either. In 2009, the Blue Oval uploaded a similar video comparing the flex under 225 pounds of weight from the bare frames of the F-150, Chevy Silverado, Dodge Ram (as it was still called at the time) and the Toyota Tundra. The results fell in the Blue Oval's favor, as you can see here.

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.
