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.

Watch the Hennessey Ford GT makes its record run at Texas Mile

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.
There's not much in the video you haven't already seen, this just makes it official. That said, who doesn't want to see a twin-turbo Ford GT set an incredible speed record? You can watch it below.

Detroit 3 and UAW set for showdown over tiered wages

This week, thousands of United Auto Workers will converge on Cobo Center in Detroit for the Special Convention on Collective Bargaining, an every-four-year event that lets members tell UAW leaders what the negotiating priorities should be during contract negotiations. This is where a lot of sand and a lot of lines start coming together in preparation for contract negotiations between the UAW and the Detroit 3 automakers, which will happen later this year. Number one on the UAW agenda is the end of the two-tier wage system created in 2007 to help the automakers get through bankruptcy; veteran workers are paid the Tier 1 rate of around $29.00 per hour, new hires are paid the Tier 2 rate of between $15 and $20 and get about half the benefits of Tier 1. Tier 2 hiring has been an undoubted success for the automakers, allowing them to keep factories in the US and hire more workers. By agreement, it is capped at a certain percentage of each automaker's workforce, and while the union's ultimate position is to get rid of the dual-scale system entirely; one leader said Ford could easily afford the $335 million it would take to convert all its workers to Tier 1 out of its $6.9 billion in 2014 North American profit, and General Motors could do the same out of the $5 billion it is handing to investors through the (admittedly forced) share buyback. Other delegates say that at the very least they'd be happy with enforcement of the current caps in the new contract. The automakers, conversely, would welcome expansion of the Tier 2 ranks. Including benefits, import automakers pay workers "in the high $40 range" per hour, according to an analyst, while Ford and GM pay about $59 in wages and benefits per hour. More Tier 2 workers on the rolls would let those two companies get labor cost parity with the competition. Fiat-Chrysler pays wages closer to the imports because of special exceptions in its UAW contract that allow unlimited Tier 2 hiring; those exceptions will end on September 14 and bring FCA into line with the other domestics, unless the new contract maintains them. FCA CEO Sergio Marchionne is opposed to the two-tier system, having called it "almost offensive." One analyst says the UAW might win a sizable pay raise for Tier 2 and a small increase for Tier 1, but the keystone issue will be how the hiring matrix can help the automakers keep overall wages in line with the imports.
