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.

Watch the Hennessey Ford GT makes its record run at Texas Mile

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.
There's not much in the video you haven't already seen, this just makes it official. That said, who doesn't want to see a twin-turbo Ford GT set an incredible speed record? You can watch it below.

2014 Ford Mustang GT

I was more than a year removed from my last experience with the Mustang GT and its delicious 5.0 V8 when this new 2014 example rolled up to my driveway recently. Good weather and a planned road trip across the state meant that I would get plenty of seat time in this conservatively specified example, too. In total, I logged about 400 miles in a week of driving - not a lot for some of you super commuters out there, but quite a lot for this work-from-home journalist.
The basic formula of the 5.0 has stayed the same for 2014. The 2013 model year saw a number of updates to keep the Mustang fresh until it's replaced with an all-new generation for 2015. So, for its bon voyage tour, the fifth-generation Pony Car has seen only a few modifications: a couple of new paint colors (Oxford White and Ruby Read Metallic), trim and wheel revisions and, sadly, the deletion of the Boss 302 from the Ford lineup. However, while the limited-edition Boss is likely to reappear sometime after the gen-six Mustang makes its debut in 2015, the GT Track Package cars like the one I tested provide at least a partial solution for those looking for hot laps.
