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.

Chris Harris checks out Ken Block's Hoonicorn '65 Mustang

Ken Block's Hoonicorn, which stars in Gymkhana Seven, might still bear a passing resemblance to a vintage 1965 Ford Mustang, but underneath the skin, the car is one of the baddest custom machines to ever do a smoky burnout on the road. The ever enthusiastic British auto journalist Chris Harris is now showing what really makes Block's new ride tick on video, and Harris even gets to go for quite a ride. The only Mustang components really left on the Hoonicorn are the A-pillar, B-pillar and roof, according to Harris. Everything else is ditched to create Block's ultimate Gymkhana tool. The 845-horsepower, 6.7-liter Rousch Yates V8 sits behind the front axle, and the grunt is routed to all four wheels through a Sadev gearbox usually found on Dakar Rally vehicles. The whole drivetrain is packed with cool little touches; like that giant handbrake that also disconnects power from the front wheels when in use. The superlatives about the Hoonicorn could go on forever, but settle in and let a very excited Harris tell you about just some of them. He's like a kid in a candy store here, and the look that combines surprise, fear and joy during his ride with Block is the kind that lacks a suitable word in the English language.

Weekly Recap: Marchionne's Manifesto again calls for industry consolidation

Sergio Marchionne isn't taking no for an answer. Despite public rebuffs from General Motors and Ford, the leader of Fiat Chrysler Automobiles continues to push for consolidation within the auto industry. His latest assertion came Wednesday when he said a combination of FCA with another automaker could net savings of $5 billion or more annually. No, this isn't about selling his company, he claimed, it's about cutting costs. Put simply, the auto industry wastes money, Marchionne said during FCA's earnings conference call. Companies invest billions to develop basic components that all cars use, but many consumers don't care how they work or recognize the differences. "About half of this is really relevant in terms of positioning the car in the marketplace," he said. "The other half, in our view, is stuff which is neither visible to the consumer nor is it relevant to the consumer." In 2014, top automakers spent more than $100 million on product development, FCA estimated. Marchionne said consolidation could save up to $1 billion on powertrains alone, noting that almost every automaker offers four- and six-cylinder engines. Not everyone has to make their own, he contended. "The consumer could not give a flying leap whose engines we are using because they are irrelevant to the buying decision." That's pretty provocative for enthusiasts, but less so for average consumers. Still, there are major differences in power and efficiency ratings, even among similar engines. Skeptics could argue consolidation would also weaken competition and reduce choices for car buyers. Marchionne stressed his presentation, curiously entitled Confessions of a Capital Junkie, wouldn't require closing factories or dealerships. It's not his final "big deal" as CEO, intent to sell FCA, or a way to elevate his company up the automotive food chain. He claims he wants to fundamentally change the industry and its habit for burning cash. "The horrible part about this, and the thing that I find most offensive, is that the capital consumption rate is duplicative," he said. "It doesn't deliver real value to the consumer and it is in its purest form, economic waste."
