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.

Ford Shelby GT350 Mustang is a lean, mean, Z/28-fighting machine [w/video]

If there's one thing you can count on, it's that the renewed rivalry between the Ford Mustang and Chevrolet Camaro will never, ever cease. For every version of Ford's pony car, there's an equally potent Chevrolet. And so with the debut of the Camaro Z/28 earlier this year, Ford has responded with a track-focused 'Stang of its own, resurrecting the Shelby GT350 name.
It looks to be a fine piece of work, this Mustang, with power coming from a naturally aspirated 5.2-liter V8 that will produce "more than 500 horsepower" and "above 400" pound-feet of torque. That grunt runs to the rear wheels via a six-speed manual transmission, and a Torsen limited-slip differential keeps everything in line.
But that's hardly the most impressive piece of the GT350 puzzle. Ford has increased the Mustang GT's chassis stiffness for duty here in the Shelby, and the coupe employs MagneRide damping which automatically adjusts based on road conditions and driver inputs. It's a first both for the Blue Oval and for the segment. And speaking of firsts, the GT350 uses a flat-plane crankshaft - something Ford has never included in a production V8 before.

2015 Ford Focus ST gets sleeker style, improved dynamics

The Brits don't really have a major auto show these days. Not in a conventional sense, anyway, with stationary vehicles under floodlights in a closed exposition space. What they do have, you could argue, is much better: the Goodwood Festival of Speed, where the public can view the latest machinery not only under an open sky, but in motion as well, speeding up Lord March's front lawn. And this year, British automakers are rolling in with some very enticing new metal.
In the past few days alone we've confirmed the McLaren 650S GT3 and MSO, Jaguar F-Type Project 7, Range Rover Sport SVR and Ariel Ace will all be revealed for the first time at Goodwood this weekend. Ford isn't, strictly speaking, a British automaker, but for all its history in the UK, it might as well. So it's chosen Goodwood as the site to unveil its refreshed Focus ST.
The upgraded Blue Oval hot hatch still packs a 2.0-liter turbo four with 252 horsepower and 270 pound-feet of torque driving through a six-speed manual to the front wheels, so we're not expecting much change in measurable performance. But Ford has given the new Focus ST a new front suspension setup and a new electric power-assisted steering rack that combine to promise improved handling.
