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.

Chip Foose tastefully enhances his personal Ford GT

Typically, we'd expect a vehicle from 2006 to fall well short of a more modern vehicle, both in terms of performance and style. Of course, the Ford GT is not your average offering from the Bush era. That's doubly true when the 2006 GT in question belongs to one Chip Foose.
Purchased by his wife as a 50th birthday present, Foose is showing his custom, personalized GT at the 2014 SEMA Show. The 5.4-liter supercharged V8 breathes a bit easier thanks to a full Magnaflow Performance exhaust, but Foose's GT isn't all about the performance.
Instead, the car customizer extraordinaire has focused on tasteful aesthetic enhancement, tweaking the rear end by removing the bumper and trimming the frame extensions. The wheels, meanwhile, are one-off aluminum alloys, designed by Foose himself. Like the stripes, the wheels feature orange accenting.

Shelby GT500 and Roush Stage 3 go head to head at the drag strip

The Ford Mustang is a brilliantly affordable source of horsepower, with a base 300-plus-horsepower version available for well under $30,000. Jumping up to about $35,000 will get you a solid 420 horsepower from a high-revving V8, while those with some extra disposable income can get a pair of 600-plus-horsepower monsters. Both the Roush Stage 3 with its Phase 3 package and Ford's factory Shelby GT500 even crest the 650-horsepower mark, with 675 and 662 ponies, respectively.
Naturally, someone needed to find out which of these hi-po Mustangs was the quickest. And while this video is quite obviously a dealership commercial, at least there's some solid drag racing between two of the most powerful performance machines available for under $100,000.
With two NHRA drag racers at the wheel, the Stage 3 and GT500 go head to head for three races. Scroll down below to see the results in the full video.
