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 rally cars go blue in the face (and everywhere else)

Well at least we now know why Ken Block "just ain't care" about smashing up his Ford Fiesta rally car recently. It's because he's getting a full brand makeover including a new team name, new paint scheme and even a new headquarters. Formerly known as Monster World Rally Team, Block and his Fiesta will now be competing under the Hoonigan Racing Division name, which is based out of a new 12,000 square foot facility located in Park City, UT.
As you can tell in the image above, Hoonigan Racing will replace the familiar black, white and green paint scheme with a more colorful design featuring plenty of blue, purple and red; the Monster Energy logo retains some of the car's green. The new paint scheme was inspired by Block's love of skateboard graphics from the '80s and early '90s as well as "Miami Vice-era" speedboats.
Block will continue to compete in multiple rally racing series such as Global RallyCross, World Rally Championship and X Games. The new headquarters features office space on one side and a shop for the cars on the other side. The building features plenty of stuff you'd expect from a company designed around Ken Block, including a massive gaming station for racing video games, recycled shipping containers used throughout the facility and a black bear.

Ford Fiesta ST GRC Racecar is hungry for podiums in 2013

As we reported earlier, the Chicago showing of this plucky Ford Fiesta ST GRC racer points to bigger and brighter days for Global RallyCross. For the upcoming season, you can expect to see Ken Block and Tanner Foust both driving the Ford racecar, and if last season's results are any indication, you can anticipate quite a few podium appearances, as well.
The Fiesta seen here was built by the Swedes at OlsbergsMSE, and will be driven in anger by Foust in 2013. Modifications are, as you'd expect, extensive, and include an engine, exhaust and braking upgrades, a racing style short-throw shifter and a limited-slip differential. As you can see, the car has been fully stripped out and caged for maximum speed and safety, too.
Refresh your memories with the details of the car, in the press releases below. And if you head out to the Chicago Auto Show this year, don't forget to drop by the Ford stand to have a look.
