2015 Ford Mustang leaked in Autoweek

We would have to imagine that Ford knew it couldn't keep its 2015 Mustang under wraps for too long, and with only days to go before the pony car's official unveiling, the dam seems to be cracking. SVTPerformance.com member Screamin 40th just posted some images taken of the sixth-gen Mustang prominently featured in and on the cover of the December 9 issue of Autoweek magazine.
These images show that recent renderings we saw weren't too far off. The face is just like what we saw in spy shots a few months back, but the rear of the car features some of its more striking cues. Starting with the pronounced haunches and hidden B-pillars, the rear view of the new Mustang might be its best with the ridged, three-bar taillights, a rear diffuser and the lack of a faux gas cap, which allows the galloping pony to be an even more prominent element against the black trim.
The images also reveal a small portion of the updated interior carrying over retro themes like the deep-dish steering wheel and dual-gauge instrument cluster, but it also adds some modern tech with a big infotainment displays and a clean center stack layout. No official word on powertrain or other specs, but while we can't make out most of the magazine's text, our eyes did catch mentions of an independent rear suspension and a 200-pound weight reduction.

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 EcoBoost already hitting 12-second quarters

The arrival of a new Ford Mustang means many things to many people, but not least of them is drag racers. The pony car has always been a mainstay of the drag strip, and the Ford Racing team aims to carry that reputation forward with this latest generation. So it cooked up a few basic modifications on three new 'Stangs and headed to the strips at US 131 and Milan Dragway to see what they could coax out of 'em.
Impressively, the 5.0-liter V8 Mustang GT with a few modifications (but no forced induction) managed to clock a quarter-mile time of 11.77 seconds. Another Mustang GT fitted with a supercharger clocked a blistering 10.97 seconds. But just as intriguing was the modified EcoBoost model that, with only four cylinders and 2.3 liters of displacement, still passed the gates in just 12.56 seconds - nearly half a second better than expected. This with modification limited to a new subframe, half-shaft, drive shaft loops, exhaust, engine calibration, slicks, roll cage and bucket seat. Well done, boys.
