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.

First Ford Mustang prototype shots caught by legendary spy shooter Jim Dunne

You know how people refer to someone as having "been around the block" to mean they're very experienced? Well, when it comes to automotive spy photography, Jim Dunne actually laid down the concrete slabs of the block's sidewalk. The unforgettable Dunne more or less invented the car spy game - a fact he cemented by writing book called Car Spy - and has been delivering spy shots and reporting on the industry for some 45 years now. (He also once employed this writer as his impromptu personal chauffer on a Volkswagen trip in Germany, while he slept, but that's a story for a different time.)
In any event, Dunne must be on a mission to prove that "elder statesman" doesn't also mean "washed up" as it is his shots of the upcoming new 2014 Ford Mustang that we've been handed by our friends at KGP Photography.
Mr. Dunne has likely spent the last few years obtaining powerful telescopic lenses, as the Ford in question has clearly been photographed from some distance. Nevertheless, what you see here is visual evidence that the sixth-generation Mustang has moved beyond the mule stage, and is now testing in proper prototype form. Sources indicate that there are production-spec body panels under that baggy canvass dress; but the slightly less bulky silhouette of the new car can be just made out. While the car's bumpers have been removed to obfuscate things, we can tell by way of the camo's apertures that the car's taillights have moved upwards and towards the lip of the tail. A fender vent appears to be visible, too, just behind the front wheel.

Shelby Mustang stars with Ethan Hawke, Selena Gomez in Getaway movie

Car movies. We keep watching them, they keep making them. Despite Fast & Furious 6 still blowing up the box office (No. 1 in theaters for the second straight week) and production on Transformers 4 being well underway (check out the Bugatti Veyron and Corvette Stingray as new cast members), there's still room on the marquee for more car movies. Next one up is an Ethan Hawke joint called Getaway, which prominently co-stars a Ford Shelby GT500. The first trailer for Getaway, which opens in theaters on August 30, was released yesterday and can be watched below.
The movie's plot centers around Hawke's character, former race car driver Brent Magna, who must somehow use this car, what appears to be a generation-old Shelby GT500 Super Snake he "commandeered," to save his wife. The movie's third co-star is Selena Gomez, whose character we're told is the owner of said Shelby. A 20-year-old having a car like this seems a bit far-fetched - especially in Europe - and on paper, this plot looks like it cribs liberally from Charlie Sheen's 1994 The Chase. But all we've got to go on is a brief plot description and the trailer below, so we'll withhold judgment until the studio firmly has our ticket money in its grasp.
The Shelby GT500 is, of course, no stranger to acting. Before this jump to celluloid, the most fearsome of all Mustang models starred in the return of Knight Rider to television on NBC back in 2008. That gig didn't pan out for the car, the show lasting only one season and 17 episodes. In fact, with its casting in Getaway, the Shelby GT500 is one of the few actors who escaped that debacle with a future in show biz.
