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.

Ford Shelby GT350 Mustang is a track-day weapon with 500 hp

Ford promises more than 500 horsepower and a torque peak above 400 lb-ft.
The wait is finally over. After months of spy shots, rumor and innuendo, Ford has officially pulled the wraps off its new Shelby GT350. Judging by the spec sheet and the promises being made - especially that the Shelby GT350 will be "an all-day track car that's also street legal" - the wait appears to have been worth it.

Takata adds millions to recall expansion in US [UPDATE]

UPDATE: Ford spokesperson Kelli Felker has advised Autoblog that of the 1,509,535 total vehicles worldwide that the company is recalling, 966,504 of them are new additions for this expanded safety campaign. Last week, the National Highway Traffic Safety Administration announced that the Takata airbag inflator recalls would expand to an estimated 33.8 million vehicles in the US. However at the time, automakers weren't sure specifically which of their models might be affected under this enlarged campaign. Now, the numbers for BMW, FCA, Ford, and Mitsubishi are being released by the agency. Additionally, Honda is outlining the broadening of its own campaign. BMW's recall amounts to 420,661 vehicles in the US, an increase from 140,696 previously. All of the following models need their front, driver's side airbag replaced: 2002-2005 BMW 325i/325xi/330i/330xi Sedan 2002-2005 BMW 325xi/325i Sportswagon 2002-2006 BMW 330Ci/325Ci/M3 Convertible 2002-2006 BMW 325i/330i/M3 Coupe 2002-2003 BMW M5/540i/525i/530i Sedan 2002-2003 BMW 540i/525i Sportswagon 2003-2004 BMW X5 3.0i/4.4i BMW has received no reports of any injures or deaths from this problem in its vehicles. FCA has 5,224,845 vehicles globally in need of inflator replacements, according to its statement. However, the company is only aware of one injury related to the issue, which occurred in a 2006 Dodge Charger in southern Florida. There are 4,747,202 vehicles worldwide from the company that are affected on the front, driver's side. Among these, 4,066,732 are in the US, 374,508 are in Canada, and the rest are in other countries. The models are: 2005-2009 Dodge Ram 2500 Pickup 2004-2008 Dodge Ram 1500 Pickup 2006-2009 Dodge Ram 3500 Pickup 2007-2009 Dodge Ram 3500 Cab Chassis 2008-2010 Dodge Ram 4500/5500 Cab Chassis 2008-2009 Sterling 4500/5500 Cab Chassis 2004-2008 Dodge Durango 2007-2008 Chrysler Aspen 2005-2010 Chrysler 300/300C/SRT8 2005-2010 Dodge Charger/Magnum 2005-2011 Dodge Dakota 2006-2010 Mitsubishi Raider Also, there are 438,156 vehicles in the US, according to the NHTSA documents, that need their front passenger's side inflators replaced in the expansion of an earlier regional recall: 2003 Dodge Ram 1500 2003 Dodge Ram 2500 2003 Dodge Ram 3500 The total number of vehicles from Ford now covered under these campaigns stands at 1,509,535 worldwide. Of this total, there are 1,380,604 in the United States, 93,207 in Canada and 16,953 in Mexico.
