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.

Shelby GT500 laps N"urburgring in under 7:40?

A couple of weeks ago we brought you footage and official times of the new Chevy Camaro Z/28 lapping the Nürburgring. With a 7:37.47 lap time, the Z/28 emerged as the fastest muscle car ever to lap the circuit. But what was missing from that picture was how fast the king of all Mustangs, the Shelby GT500, could manage to lap the Nordschleife.
Ford never released any information or footage of the GT500 on the Nürburgring that we were aware of - that is, until the guys at SVTPerformance.com put in a request for Mustang videos. Among the clips they received was never-seen, in-car footage of the Shelby GT500 lapping the circuit. And boy did it hustle.
Although not quite official, the video seems to show the GT500 lapped the venerated German track in a touch under 7:40. That would make it a tick or two faster than the Camaro ZL1 - but what of the Z/28? By Chevy's quoted time, the Z/28 is still faster than the GT500, but SVTPerformance suggests GM may have fudged the numbers a bit and scrubbed half a second or so off their lap time.

Ford Focus RS will go global, come to US

"We are transforming our approach to performance." – Mark Fields Ford will launch a new high-performance Focus RS around the world, including the United States, company CEO Mark Fields confirmed at a press conference Thursday morning. It is expected to debut in January at the Detroit Auto Show, though launch timing is unclear. "We are transforming our approach to performance," Fields said. The RS will serve as a hotter variant of the Focus, which will be redesigned next year as part of Ford's 16 product launches. Our spy photographers have already captured images of a purported RS, which you can see above. Ford last sold a Focus RS in Europe in 2009, and it continues the long lineage of RS-badged performance cars, which dates to 1968. "The RS has a significant heritage and pedigree," Ford product chief Raj Nair said. The Focus RS will slot above the Focus ST, which will continue, a spokesman said. The ST runs a turbocharged, 252-horsepower four-cylinder that's paired with a six-speed manual transmission. It also has chassis and design upgrades to reinforce its athletic dynamics. The most recent intel suggests that the new RS could use Ford's 2.3-liter turbo-four, tuned to anywhere from 325 to 350 hp. All-wheel drive is also rumored to be part of the new RS formula. Meanwhile, Ford announced it is putting all of its sporty units under the umbrella name of "Ford Performance," which will be led by Mustang chief engineer Dave Pericak. Ford Performance will include Ford Racing, SVT (which is responsible for the Raptor and Shelby GT350) and RS. "We're changing Ford's performance business," Nair said. Ford is placing a renewed emphasis on performance, as the customers tend to be younger, wealthier and better educated, Nair said. In other news, Nair said the company is working on a Raptor version of the new, aluminum-bodied F-150, which launched this year. "I want to get it out as quickly as we can," he said.
