Shelby boosts production of 575-hp Raptor on early demand

Shelby American unveiled its all-new Shelby Raptor at the New York Auto Show last month, saying that it would build just 100 examples of its off-road bad boy, a pickup priced at $17,995 over the cost of the donor Ford F-150 SVT Raptor. But the Las Vegas outfit apparently underestimated just how popular the supercharged 575-horsepower 4x4 would actually be.
Strong early demand reportedly has Shelby singing a whole new tune, as the company is now saying it will build upwards of 500 units annually. While the increased production will likely make for at least 400 more happy owners, those who were on the original short list - possibly speculating on future values - might not be grinning as much. Needless to say, the company has assured everyone that each and every one of the modified Raptors will still be listed in the official Shelby registry.
Keep in mind that Ford isn't sitting idle on its trophy-truck-for-the-street, either. The company will reveal its own 2014 F-150 SVT Raptor Special Edition this month.

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.
