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.

Hertz Penske GT latest hot Ford Mustang at the rental counter

Just a couple days after announcing the resurrection of its Rent-A-Racer program, Hertz has revealed a new car being added to its Adrenalin Collection of rental cars. To signify its new partnership with Penske Racing in NASCAR, Hertz introduced a limited-edition version of the Ford Mustang GT, officially called the Hertz Penske GT, at last weekend's NASCAR races in Daytona. If you're like us, the rental specials remind with the original 1966 Shelby GT350-H and its later homage, the 2006 Shelby GT-H.
Visually, the Hertz Penske GT starts out with a black and yellow paint and graphics scheme as well as identifying badges, and Hertz has raided the Mustang parts bin for bits and bobs like a Boss 302 front splitter and Shelby GT500 rear valence to give the coupe its own unique look. The model has also receives performance improvements including upgraded suspension and exhaust, Brembo brakes, a retuned ECU and Recaro bucket seats. As a bonus, Penske Racing's Nationwide Series No. 22 Ford Mustang has been painted to match the new Hertz Penske GT. Other cars in the Hertz Adrenaline Collection include the standard version of the Ford Mustang GT, Chevrolet Camaro SS, Chevrolet Corvette convertible and Dodge Challenger R/T. Scroll down for the official press release for the Hertz Penske GT, or you can always head to your local Hertz airport location to see if they have one on the lot.

Airbag recall widens to include BMW, Chrysler, Ford and Toyota

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a roll in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time.
BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall.
Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands
