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.

Report: GM struggling to market turbo technology

In the automotive realm, marketing can sometimes prove just as important as the actual product. Take, for instance, Ford's well regarded EcoBoost technology, which couples turbocharging with direct injection to produce more horsepower and reduce fuel consumption. Would it surprise you to hear that General Motors has had similar technology on the market for over three years?
It's true. GM's first turbocharged, direct injected powerplants hit the market for the 2007 model. The 2.0-liter Ecotec mills put down an impressive 260 horsepower and a matching 260 pound-feet of torque, and they were lauded by the press in the engine bays of the Pontiac Solstice, Saturn Sky, Chevrolet Cobalt SS and Chevrolet HHR SS. But few people outside a core group of enthusiasts actually remember this fact.
Says Uwe Grebe, executive director of GM's global advanced engineering, "We didn't have a badge and say, 'This is the most important thing we will put on all our brochures.'" Ford, however, did just that, and it's EcoBoost engines are right at the tips of all our tongues when we discuss today's most advanced powerplants. So, how does The General fix its mistake?

2015 Galpin Ford GTR1

Last year in Monterey, we met GTR1 for the first time. Galpin Auto Sports pulled the wraps off its Ford GT-based supercar, powered by a twin-turbocharged 5.4-liter V8 good for a whopping 1,024 horsepower and 739 pound-feet of torque. The thing was totally custom-made and reportedly took some 12,000 man hours to create. And there it sat on the Pebble Beach grass, $1,000,000-plus price tag and all.
This year, the Galpin was back, albeit with one big change. That twin-turbo engine? Gone. In its place, a 5.4-liter V8 with a 4.0-liter Whipple supercharger bolted on, delivering an astonishing 1,058 hp and 992 lb-ft of torque on 110-octane fuel. 0-60? 2.9 seconds. Top speed? Somewhere above 225 miles per hour.
"Some things to keep in mind: no stability control, no traction control," were the only warnings given by Galpin's Brandon Boeckmann before taking me on a quick spin in the supercar. And after having my eyes thrown into the back of my skull a few times, laughing hysterically and trying to regain full use of my hearing after my ear drums being bombarded by the apocalyptic roar behind me, Brandon pulled over and said it was my turn, if I was ready to take the wheel.
