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.

New Ford GT to carry $400k-price tag

The last time Ford made a GT, it built more than 4,000 of them and sold each one for around $150,000. Judging by the premiums at which they later traded, they were evidently worth a lot more than that. But this time, the new Ford GT will be far more expensive and far more scarce. Official performance, production and pricing figures have yet to be released, but upon the new American supercar's European debut in Geneva, Ford performance chief Dave Pericak indicated it would be priced competitively with the Lamborghini Aventador – which carries a base sticker price approaching $400,000, Car and Driver reported. Combine that with production expected to number in the hundreds, not the thousands, and you're not likely to be seeing any of these Blue Oval halo cars in your neighborhood anytime soon. The question then becomes: will the price tag will be justified? With carbon-fiber construction and more than 600 horsepower on tap, it very well could be. And if speculators are going to drive up the actual sale prices, we don't see why Ford shouldn't get what the product is worth. But whether the world is ready for a $400,0000-Ford is another question entirely. Related Video:

Toyota fears supplier pressure in Australia with GM pull out

With Ford and General Motors both announcing an end to production in Australia, the country's auto industry is in a bad way. With the exit of two big players, there's increased concern that a third Australian manufacturer, Toyota, will be forced out, as well.
"We are saddened to learn of GM Holden's decision. This will place unprecedented pressure on the local supplier network and our ability to build cars in Australia," Toyota Australia said in a statement. The GM closure of Holden production will be the direct end to 2,900 jobs, but will also force a dramatic reduction in the size of the country's supplier network, as there will simply be fewer cars to build.
In the same statement, Toyota Australia said it would work with suppliers and local government to figure out whether continuing production Down Under was even feasible. According to Automotive News, a representative for the Australian Manufacturing Workers' Union told reporters it was "highly likely" that Toyota would also close up shop within the next few years.
