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 director says company has big efficiency plans, but no dedicated EV

The annual autofest known as the North American International Auto Show previews a plethora of exciting new products that we'll see and drive later in the year, from tiny urban commuters to family sedans and crossovers to hard-working big pickups and SUVs. It's also a once-a-year cornucopia of auto executives and leaders from around the world. "There will be some really fun stuff that you'll hear about in the future" - Ford's Kevin Layden So, in-between dozens of cool new-product unveilings on rotating stages during the two press days preceding the public show, we auto scribes grab what planned and impromptu interviews we can. Sessions with top industry leaders can be hard to get, but I was able to score a seat in a group session with then-General Motors North America president (now executive VP of global product development) Mark Reuss, and I also managed brief one-on-ones with a trio of vehicle electrification leaders, one each from Ford, BMW and GM, and what they said then remains relevant now. First up is Kevin Layden, Ford's Director of Electrified Powertrain Engineering. ABG: Where will Ford go beyond its current Focus EV and hybrids, and will there be a Ford EV and/or hybrid on its own energy-optimized platform one day. KL: We don't want to do a dedicated electric vehicle with all the development costs borne by a niche product. At the Michigan Assembly plant right now we're building the Focus electric, PHEV and EcoBoost on the same assembly line. Also the C-Max, with both a hybrid and an Energi plug-in, and we use that same power pack in the Fusion Hybrid and Energi. We want to be, "The power of choice" [a Ford marketing slogan], so having that choice for customers is very important. And if I want to sell the Fusion, Focus and C-Max globally, we can use these power packs wherever it makes sense. So as we go forward, you'll see us proliferating the power packs we have today. Then the question is, what do we do next? There will be some really fun stuff that you'll hear about in the future. ABG: Is the efficiency difference between a dedicated ultra-efficient vehicle platform and a shared multi-use platform getting smaller as all platforms get more efficient? KL: Exactly. Were going through aero studies now on wheels and tires and hood sealers on base vehicles. We have full aerodynamic wind tunnel studies going on with the base Focus and C-Max, so all of that [aerodynamic improvement] will be there for EVs.

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.
