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.

What's in a trademark? Sometimes, the next iconic car name

The United States Patent and Trademark Office is a treasure trove for auto enthusiasts, especially those who double as conspiracy theorists.
Why has Toyota applied to trademark "Supra," the name of one of its legendary sports cars, even though it hasn't sold one in the United States in 16 years? Why would General Motors continue to register "Chevelle" long after one of the most famous American muscle cars hit the end of the road? And what could Chrysler possibly do with the rights to "313," the area code for Detroit?

Ford Mustang GT350 seen and heard in motion for the first time

We just recently saw our first spy shots of the next-gen hi-po Ford Mustang slated to replace the Shelby GT500, but now we're getting our first look - and listen - of prototypes captured on video. Mustang6g.com has the video (along with some different spy shots), which show that, if nothing else, SVT knows how to tune an exhaust system. The :50 mark is a good example of this, but fast-forward to around 2:00 where the driver revs the engine and really gets on the throttle hard taking off from a stop.
There's still no definitive evidence that the next-gen SVT Mustang - said to be called GT350 - will be naturally aspirated, but it sounds just as menacing as the current Shelby GT500. While the video posted below exhibits the sort of quality that is to be expected from someone driving while trying to film someone who is attempting to elude being filmed, it's still exciting to see and hear this new Mustang in motion.
