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 S-Max Concept previews new look, technology for Euro seven-seater

Ford unveiled today the S-Max Concept, which comes with a new, sleek look and loaded with innovative technology, such as a heart-rate monitoring seat. But if you're heart is set on a minivan sports activity vehicle (SAV) and you live in the States, don't wait for this one - it's a Europe-only product, and we don't expect that to change when the next-gen S-Max is released.
The styling follows Ford's global design language, looking a bit like an overgrown Focus hatchback with the company's signature grille, wraparound headlamps, steeply raked windshield and curved roof line. Ford also implemented details to make the S-Max look longer and faster, such as a feature line on each side of the vehicle and muscular-looking fenders. The engine isn't Ford's most powerful, but the new 1.5-liter EcoBoost four-cylinder engine should be potent enough with turbocharging and other efficiency related technologies.
Ford says the new interior, which seats up to seven people, features high-quality materials and fine detailing, such as an "ultra-soft" leather wrap for the instrument panel and leather and carbon-fiber details on the seats. Ford's Sync connectivity system with MyFord Touch makes the car a wireless hotspot, and there's a tablet docking station for second-row occupants.

Motorweek goes retro with '80s hot hatch shootout

Motorweek's decades of history on television make it the perfect medium to look back into the automotive past and see how things are different now. It recently added old road test videos to its YouTube channel of the Acura NSX and Toyota Supra, as well as the Ferrari F40. For one of its newest flashback clips, Motorweek has exhumed an affordable five-car challenge of 1986's premiere hot hatches.
By today's standards, this is an eclectic field that features fondly remembered classics like the Volkswagen GTI 16-valve and Acura Integra. However, it also throws in some nearly forgotten contenders like the Dodge Colt Turbo and Ford Escort GT. The angular Toyota Corolla FX16 GT-S rounds out the group.
It's fascinating to watch Motorweek run the quintet through the slalom, down the drag strip and on various roads. What's most striking in this clip is the difference in the definition of a performance car between then and now. With its 16-valve, 1.8-liter four-cylinder, the GTI is the burliest of the contenders with 123 horsepower, but it still takes 8.8 seconds to reach 60 miles per hour. By today's standards, that would make it a plain-jane economy car, and not even a particularly quick one.
