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.

Subcompact sales slump, yet again

US Ford Focus RS to be imported from Europe

Rumors about the forthcoming Ford Focus RS are flourishing into what sounds like a very impressive new hot hatch. The latest scuttlebutt gives the first indication about when we might see a few of these fast Focuses on roads here in the US.
Unnamed insiders reportedly confirmed to The Truth About Cars that Ford plans to launch the Focus RS in the US in 2016. However, getting one might not be so easy - the boosted powertrain means the car would likely need to be imported from Europe. That's likely going to keep the total number available in the US rather low. The sources estimate a price tag that's a bit more expensive than the top Focus ST3, which starts around $28,500, plus $825 destination.
It seems that a pretty potent package comes for all of that cash, though. The Focus RS reportedly uses a 2.3-liter turbocharged four-cylinder making between 325 and 350 horsepower, with a torque-vectoring all-wheel drive system to get that muscle to the road. The test mules also wear more aggressive front and rear fascias, dual exhaust tips, larger brakes and sticky tires. It sounds like a great formula on top of the already enjoyable Focus ST.
