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.

Pickup prices rising at 2x industry average

We've said it before, but bears repeating: Pickup trucks are the financial engines of America's automakers. Good thing, then, that the segment is in rude health - in fact, Automotive News is suggesting that pickup truck sales are arguably healthier than they were pre-recession, even though the segment's volume is still significantly down from where it was before the bottom fell out of the US economy. That's because per-unit profits on full-size trucks are skyrocketing, outpacing the industry's average price increases by more than double since 2005. According to data from Edmunds, the average transaction price of a full-size pickup is now $39,915 - a heady increase over the $31,059 average price in 2005 - a gain of over 8 percent after inflation is factored in.
Just how important are trucks to automakers' bottom lines? Automotive News quotes a Morgan Stanley analyst as saying the Ford F-Series is responsible for 90 percent of the company's 2012 profits, and General Motors isn't far behind, with the Chevrolet Silverado and GMC Sierra twins chipping in about two-thirds of the automaker's earnings.
Automotive News points out that Detroit's automakers now have the money to invest in modernizing their full-size truck offerings, in part because they don't have the same overhead and legacy costs that pushed General Motors and Chrysler into bankruptcy. Certainly, the pickup segment has seen a lot of innovations as of late, including turbocharged V6s, coil-spring rear suspensions and active aero. Those improvements in important areas like fuel economy and ride comfort have given existing pickup buyers new reasons to upgrade. In addition, automakers are piling on the tech and luxury goodies, creating more and more high-content, high-profit models like the Ford F-150 King Ranch, Ram 1500 Laramie Longhorn and Chevrolet Silverado High Country (shown).
