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.

Ford Fiesta ST GRC Racecar is hungry for podiums in 2013

As we reported earlier, the Chicago showing of this plucky Ford Fiesta ST GRC racer points to bigger and brighter days for Global RallyCross. For the upcoming season, you can expect to see Ken Block and Tanner Foust both driving the Ford racecar, and if last season's results are any indication, you can anticipate quite a few podium appearances, as well.
The Fiesta seen here was built by the Swedes at OlsbergsMSE, and will be driven in anger by Foust in 2013. Modifications are, as you'd expect, extensive, and include an engine, exhaust and braking upgrades, a racing style short-throw shifter and a limited-slip differential. As you can see, the car has been fully stripped out and caged for maximum speed and safety, too.
Refresh your memories with the details of the car, in the press releases below. And if you head out to the Chicago Auto Show this year, don't forget to drop by the Ford stand to have a look.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.
