NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.

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.

How Ford secretly used customers to test its aluminum F-150 [w/video]

Automakers getting clever about disguising development vehicles isn't anything new. Between mules wearing the sheetmetal of other cars and prototypes decked out in as much camouflage as is practical, automakers know how to make it very difficult for the general public to get an exact idea of what kind of vehicle is in development. Ford, though, is rapidly becoming the master.
We knew that the Blue Oval originally tested the durability of the aluminum construction being used for the 2015 F-150 by building an all-aluminum 2014 truck and entering it in the Baja 1000 off-road race. That's no longer a secret. What we didn't know, though, is that the aluminum development dates back to before even that, and that some of the people in question had no idea what it was they were working with.
Ford says this is the first time prototypes have ever been handed over to the public.
