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.

2013 Shelby GT350

Shelby is a name as synonymous with the Ford Mustang as marshmallows are with campfires. But unlike the short-lived sugary confection that is prepared on a stick, the late Carroll Shelby's name on the placard means added performance and exclusivity. Launched in 1965, the automaker's celebrated early cars were in production for a limited run - today, a mint concours-quality 1965 Shelby GT350 can sell for upwards of $350,000.
To coincide with the 45th anniversary of the original Shelby GT350, Shelby American reintroduced the GT350 in 2011. Like the original, it was only offered in white with blue stripes. Customers were offered a choice between naturally aspirated (440 horsepower) and two levels of supercharging (525 horsepower with a warranty or 624 horsepower without). The manufacturer calls the GT350 a "post-title" package, a term that means it starts out life as a stock Mustang and is modified outside Ford's factory (this is in contrast to the Shelby GT500, which is a standard Ford production car).
As the GT350 enters its third year, Shelby has made several changes. Mechanically, Wilwood brakes replace Baer units and Recaro seats and a tinted glass roof are on the options list. Cosmetically, the vehicle is now offered in most of the Blue Oval's factory colors, new multispoke wheels are available in Satin Black or Bright Silver Metallic finish, and customers can choose between Satin Black, Silver or Gloss White stripes (or Azure Blue Metallic on Performance White or Ingot Silver). Aesthetically, the look of the car has also changed somewhat - keen eyes will note that it actually appears more 'stock' than it did last year.

Forza Horizon announces January Recaro Car Pack with LFA N"urburgring Edition

Another month, another car pack for Forza Horizon. This time it's the Recaro Car Pack featuring a motley gang of cars and trucks: the 1983 GMC Vandura G-1500, 1995 Ford Mustang Cobra R, 2012 Cadillac Escalade ESV, 2005 Mercedes-Benz SLR, 2012 Lexus LFA Nürburgring Edition and 2012 Lotus Exige S.
It'll be up for download on Xbox Live on Tuesday, Jan. 1, 2013 for 400 MS Points. As usual, if you have the Forza Horizon Season Pass you can get them all free, and Season Pass holders will also get a bonus car that's not pictured: the 2009 Pagani Zonda Cinque Roadster.
The Pagani is everything opposite to that Vandura, but while you might not ever win anything with the van, you can always use the back of it as a place to give out free hugs. Check out the video and press release below for more details.
