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.

Ken Block and friends race light in silly-beautiful Castrol commercial

How does one make fast, loud, drifting cars better? Well, you can add more fast, loud, drifting cars or you can add lasers. Either or, really. In this case, Castrol did the right thing and added both, creating a highly stylized commercial for its Edge Titanium motor oil starring South African racer Adrian Zaugg, BMW factory driver Augusto Farfus, Audi DTM and Le Mans staple Mike Rockenfeller and some bloke named Ken Block.
Their cars? No surprise, but Block is in his Ford Fiesta GRC, while Zaugg samples a Lamborghini Aventador and Farfus and Rockenfeller drive along party lines, with a BMW M4 and an Audi R8, respectively. And those cars look good, too, thanks to the creative light and laser work on display.
Take a look below for the video from Castrol.

Sunday Drive: Still thankful for supercars

The Thanksgiving holiday meant that last week was pretty short on stories, but apparently our readers are still thankful for supercars. The biggest news of the week was the new Aston Martin Vantage, which is clothed in a new look that Autoblog readers are still very much unsure of. It's a radical departure from past Aston Martin models, and while everyone seems to agree that the profile is lovely, the squinty headlamps are a particular source of contention. Its 503 horsepower and 512 pound-feet of torque cannot be argued with ... oh, and a V12 may be coming soon. Moving along is a nearly new 2006 Ford GT for sale that's expected to fetch around $300,000 at auction. It's so unused that it still has plastic wrap covering the leather interior. The Ango-American theme continues with the McLaren 720S, though not in road-going form. Still, renderings of the upcoming 720S GT3 racer round out this supercar-rich recap.
