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.

2015 Ford F-150 specs revealed, EcoBoost 2.7L to make 325 hp and 375 lb-ft [w/video]

Our new man Greg Migliore is in attendance at a Ford media event at the Blue Oval's Dearborn, MI headquarters today, and he's reported in with a handful of the 2015 F-150 stats that we've been dying to know. Ford is slow-playing the news release here, but we can still offer up some interesting output and performance figures after half-year of waiting.
We have all be quite aware that Ford's shift to aluminum construction would save a lot of weight for F-150 models, and the results we're hearing now are duly impressive. For instance: in Super Crew trim, a 2015 F-150 is a whopping 732-pounds lighter than was its closest 2014-model-year equivalent. That's like hauling three middle-aged dudes to your bowling alley's league night for free. Polish your balls, guys.
Ford isn't willing to offer up any actual curb weights just yet, but if we take that 732-pound loss and extrapolate with the 5,128-pound curb weight of the 2014 F-150 Super Crew with the 3.7-liter V6, we can guesstimate that 2015 models will measure out in the 4,400-pound range. That's impressive.

2016 Ford Focus RS may yet be AWD, US sales likely

When it comes to forbidden fruit, few vehicles are spoken of in as hushed a tone as the Ford Focus RS. The turbocharged, five-cylinder hot hatch could only be seen from afar by American customers as it tore up the roads of Europe. And while it's safe to say that Ford's Yankee fans are quite happy to now be on equal footing with drivers in the old country thanks to the Focus ST, we doubt there'd be much protestation over a successor to the RS arriving stateside.
Of course, we've seen images of the new RS undergoing testing, but a new story by Road and Track aims to fill in some very large blanks in our knowledge of that car, thanks to a pair of mysterious insiders at the Ford. Chief among those is this - the RS will almost certainly make its way to the US, albeit in limited quantities. It gets better, though.
Under hood, the new RS is unsurprisingly expected to borrow the 2.3-liter, turbocharged four-cylinder from the 2015 Ford Mustang and 2015 Lincoln MKC. While that twin-scroll turbo produces 310 horsepower in the Mustang and 285 ponies in the MKC, R&T expects the RS to deliver quite a bit more firepower - 325 to 350 hp, with preference going to the higher output due to the limited-edition nature of the RS. This roughly fits with previous reports.
