How did Ford keep the GT a secret before Detroit?

True secrecy is a rarity in the automotive industry. Sure, companies try to keep their future projects under wraps all of the time, but usually a spy shot or blurry development photo leaks out. The complete lack of any hard details before its unveiling likely helped make the Ford GT one of the biggest stars of the 2015 Detroit Auto Show. Not only was it the favorite of Autoblog's editors, but the supercar scored a prestigious EyesOn Design Award, too. Rumors about the vehicle had circulated for weeks before the show, but no one really knew much about the GT until it rolled onto the stage for Ford's press conference in Joe Louis Arena. Amazingly, the Blue Oval kept things mostly a secret during the car's 14- month gestation period prior to its debut. According to Automotive News, the GT project began in late 2013 by a skunk works team, including six designers, that guided the supercar along from birth until the unveiling. Ford kept things clandestine by locking the vehicle in a basement storage room, and only the group members got a key to the lock. Much of the development was also done at night to further keep the secret, but occasionally the prototype was hauled outside on weekends to check it out in natural light. Because of the speed in getting the development done and for even more stealth, the designers didn't get input from the Blue Oval's other styling teams around the world. But that was somewhat of a double-edged sword. "You don't actually get to bounce opinions off people," Ford design boss Moray Callum said to Automotive News. "We were on tenterhooks ourselves until the first people saw it." Even now, there are still mysteries surrounding the GT. There's still no official word on the supercar's power; just that it's over 600 horsepower. There are also the persistent rumors going back months that the Blue Oval plans to take the GT racing to celebrate the 50th anniversary of automaker's Le Mans victory. Although, maybe this time the secrecy wasn't so good because we might have got a glimpse of the racer, recently. Related Video:

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.

Feds open investigation into Chevy Express, Ford Freestar rust issues

'Tis the season... for road salt. And with that, comes rust. And what does rust bring? Well, for Ford and General Motors, a National Highway Traffic Safety Administration investigation. According to The Detroit News, NHTSA is looking into potential recalls issues with Chevrolet Express vans and Ford Freestar minivans.
The feds have received five complaints that rust has caused leaking fuel filler pipes on 2003 Express vans. Separately, seven complaints have been filed over excessive rust in the rear wheel wells of 2004 Ford Freestar and Mercury Monterey minivans. The Freestar and Monterey went out of production in 2007. Neither issue has resulted in any crashes or injuries, according to the report.
