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.

1964 Ford GT40 prototype sells for $7M

Seven-figure Ferraris are not horribly rare. Heck, an eight-figure Ferrari isn't a rare occurrence. Between modern masterpieces like the Enzo and more classic offerings, cracking the million-dollar mark isn't a particularly tall order for the cars from Maranello. For a Ford, though, it's a big deal.
Now, this is not just some rare Mustang. This is a GT40, the car that Henry Ford II commissioned to whip Enzo Ferrari around a track in France. As far as the Le Mans-winning racers go, they don't get much rarer than this one. Sold at the Mecum Auctions in Houston, this is one of the prototypes, meaning it's one of the very first GT40s ever built. That makes its $7 million winning a bid, a record for on-air coverage of the auction, a pretty darn impressive figure.
You can watch the auction below, but first, take a look back at our original story on this rare Blue Oval.

Ford shows off V8-powered Ranger headed to Dakar Rally

Avert your eyes now if you're jealous that the global version of the Ford Ranger is not offered in the US. Ford's midsize pickup is being tuned up to take on the 2014 Dakar Rally, and the result is a truck that is probably even cooler than any F-150 SVT Raptor we've ever seen in the States. Ford is actually building two versions of the truck for Dakar, which will run from January 5 through January 18, covering more than 5,000 miles from Argentina to Chile.
Starting with a fully composite body and a 5.0-liter V8 plucked from a Mustang, nearly every aspect of the trucks have been purpose built to take on the grueling race. This includes things like the six-speed sequential gearbox, liquid-cooled rear brakes and the 132-gallon fuel tank. As proof that Dakar is more about endurance than speed, the engines used in these race trucks will be limited to around 350 horsepower and 413 pound-feet of torque, and will max out at a top speed of just 105 miles per hour. Scroll down for Ford's official press release offering more information about the trucks and teams being prepped for Dakar.
