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.

Leno talks racing with NASCAR racer Joey Logano

Jay Leno has to be under significant pressure knowing the appetite his fans have for a new Jay Leno's Garage video every week. This time, Jay takes a break from his usual format (something he's been doing with some frequency as of late) and goes back to his roots as a talk show host. There's no classic in the garage his episode with an interesting story to tell and a sumptuous exhaust note. Instead, the focus is purely on interviewing 23-year-old NASCAR racer Joey Logano about what it's like to be a racecar driver in his Ford Fusion.
Logano started racing at the tender age of six and has risen up the circle-track ranks to the big show of the NASCAR Sprint Cup. The two of them talk about what it's like to compete in the sport today compared to yesteryear, and Logano shares some racing anecdotes. Of course, they also get into what it's like to be on the racetrack controlling a car with about 850 horsepower, a four-speed manual transmission and brakes without any power boost. Scroll down to watch the video.

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.
