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.

2015 Ford Mustang gets pricing, configurator and less weight than expected

It's here; it's finally here. No more speculating or looking at dealer order guides, the configurator for the 2015 Ford Mustang is finally online. That means you should put down whatever you're doing and build your new 'Stang. Weight data for the new model has also leaked out, and while there is an increase, it's less than previously rumored.
The basic V6 coupe carries a base price of $23,600, plus an additional $825 destination charge for all models. Upgrading to the 2.3-liter Ecoboost costs $25,170, and the Ecoboost Premium is $29,170. If you need a V8 in your life, the Mustang GT is $32,100 or $36,100 with the Premium package. That puts the starting price up about $1,000 over the previous generation for the V6, but the turbocharged four-cylinder starts about $1,400 less than the V6 Premium, which is no longer available. Prices for both V8 models jumped about $1,000, as well.
If you need the convertible Mustang, the V6 starts at $29,100, excluding destination, $1,590 more than last year. The Ecoboost Premium 'vert is $34,670, and the GT droptop is $41,600.

Mazda Turnpike in Japan shut down for racing

The people behind Motorhead Magazine in Japan clearly have some friends in high places. Not only did they manage to shutdown eight kilometers of the Mazda Turnpike up the Hakone mountain, but they invited some of the country's premiere racers to take a drive up the hill. This wasn't just a Sunday cruise either. Featuring a BMW Z4 from the Super GT series, a classic Ford GT40, two flavors of Nissan GT-R and two takes on the Subaru Impreza WRX STI, these guys came ready to run. When an opportunity to let racecars challenge a curvy mountain road presents itself, you don't squander it. Thankfully, the folks at Motorhead knew that and outfitted the course with a plethora of cameras and high-quality sound equipment to capture the action. The result is nothing short of sublime. Take the video's urging to turn up your speakers for this one, and watch as these racers hit ludicrous speeds in a beautiful place never meant for them.
