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.

NHTSA probing 2000-2003 Ford Taurus and Mercury Sable models over throttle issue

A potential issue with the speed control cable collar has got the 2003-20003 Ford Taurus and Mercury Sable under the spotlight of the National Highway Traffic Safety Administration. If the collar breaks it can cause the throttle to be stuck open.
The issue is limited to vehicles with the 3.0-liter V6 Duratec. There are just 50 complaints so far out of 310,000 cars, but the NHTSA has begun an investigation into whether a recall should be issued.

What do you do with a fake Bugatti Veyron for $60k?

Replica cars are a challenging labor of love because builders spend countless hours recreating a vehicle that people immediately compare to the real thing. Perhaps, the person behind this Mercury Cougar-based Bugatti Veyron should look for another way to pass that time. The coupe is currently for sale on eBay Motors for $59,900. The builder deserves some credit because the fiberglass body looks acceptable in the photos from farther away. The car might even fool a few people from a distance. However, the devil is in the details, and the closer you look, the worse this gets. The side intakes are especially rough. The red interior is atrocious. It's essentially the Cougar's cabin but in an eye-searing shade accented with lots of fake carbon fiber. The seller's eBay Motors ad really tries to market the look, though. "You slide in to [sic] this extremely comfortable leather interior and you feel like your bank account just quadrupled in size," the listing says. Don't expect to win any top speed titles in this Veyron replica, either. Rather than a mid-mounted quad-turbo W16, a 3.0-liter V6 from a Mercury Sable sits at the front. Thanks to an upgraded intake and exhaust, the seller claims, "It doesn't sound like your grandmas [sic] Sable." We wish the seller the best of luck, but the asking price of nearly $60,000 is probably too optimistic. We would still think twice about buying it even after taking a zero off that figure, but at least this thing is fun to look at. Related Video:
