Ford recalling select Taurus, Explorer and Lincoln MKS models over fuel tanks

Ford is recalling certain 2012 Taurus, 2013 Explorer and 2012 Lincoln MKS models over fuel tank concerns. According to the National Highway Traffic Safety Administration, vehicles built between July 19, 2011 and March 15, 2012 may have been built with fuel tanks that have a "marginally sealed seam" on the side. Those seams may not provide the strength necessary to protect the tank from rupture during a collision. They may also leak. The recall covers a total of 3,037 vehicles. NHTSA says that leaked fuel, in the presence of an ignition source, could easily cause a fire.
Dealers will inspect the tanks and replace them as need be free of charge. Owners can expect to be notified once the campaign begins on or around April 22, 2013. You can read the full NHTSA recall notice below for more information.

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.

Toyota again claims Corolla outsold Focus worldwide

Toyota isn't convinced the Ford Focus was the best-selling nameplate globally last year. Bloomberg reports that for the second time in seven months, both Toyota and Ford are laying claim to the title. Ford cites R.L. Polk & Co. data that says the automaker moved some 1.02 million Focus models in 2012 compared to just 872,774 Toyota Corolla units. But Toyota says the actual figure is closer to 1.16 million Corolla models.
Last year, Ford said it took the sales crown through the fist half of 2012 based on information from IHS Automotive, but Toyota pointed out those numbers left out models like the Corolla-based Matrix and Auris, as well as the Corolla Fielder and Scion xB-based Corolla Rumion. Whether or not Toyota's belief that all these cars should be counted in the Corolla bucket is accurate or not is seemingly up for debate... as is the question of why it matters so much to both parties.
This time around, Ford is holding the line that the Focus is the "best-selling nameplate," with Erich Merkle, a US sales analyst with Ford saying the company's figure is, "a pure number that is verified by a third party." Toyota, meanwhile, has requested clarification from Polk.
