Ford Mustang SVT caught looking fierce on the 'Ring

The next-generation Ford Mustang SVT is one of the most anticipated performance cars of the moment. We've already seen it testing multiple times, but it has always been covered is some very heavy camouflage. However, Ford has just given us our best view yet of the new muscle car. According to our spy photographer, the Mustang was at the Nürburgring for high-speed testing, which meant that the Blue Oval had to remove most of the heavy obfuscation that the SVT has worn previously.
The stylish, more revealing camo makes picking out some of the more interesting details about the SVT rather easy. Starting from the front, there is the big hood scoop to feed cold air to its still mysterious engine. You can also immediately make out the model's new grille and lower front air dam. It has a vertical piece running from the bottom of the hood all the way to the ground. The aggressive styling almost gives the 'Stang the look of two fangs ready to bite down. The hood seam is even taped off here, which shows us its outline.
Around the side, it appears that the front and rear fenders are wider than stock, and the sills are certainly much larger. You can also just make out the SVT's bigger brakes behind its black wheels with a polished lip. Finally, at the rear, things appear mostly stock other than the diffuser that the exhaust outlets nestle into.

GM also sheds parts from its pickups to boost payload ratings

The row between Ford and Ram over who boasts the best-in-class tow rating for heavy duty pickups has revealed a number of things. Chief among them is a report that Ford removes items like the spare tire, jack, radio and center console from its vehicles in a bid to lower its base curb weight and therefore keep the truck's gross vehicle weight rating down.
For those that need a refresher, GVWR is the vehicle's curb weight plus its maximum payload. A lower GVWR allows Ford to station its F-450 among the so-called Class III pickups, despite the fact that internally, it has the makings of a more brutish Class IV truck.
Ford explains away these deletions, saying a customer could order their vehicle in such a manner. It has also come to light that Ford is not the only automaker to engage in such practices.

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.
