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 hybrids getting update to improve fuel economy

Ford has announced that it is introducing "calibration updates designed to improve on-road fuel economy for owners of the 2013 Ford C-Max Hybrid, 2013 Ford Fusion Hybrid and 2013 Lincoln MKZ Hybrid."
We can speculate that these changes are at least due in part to lawsuits over mileage claims of hybrid vehicles. The automaker is enhancing 2013 models starting in August by raising their electric cruising speed to 85 miles per hour from 62 mph, optimizing the use of active grille shutters and the climate control system, shortening the engine warm-up period by 50 percent and reducing electric fan speed to minimize the fan's energy consumption.
It bears mentioning that Ford is doing pretty well in the US electrified vehicle market this year. The company claims to have grown its share in the segment by 12 points to 16 percent while taking a high number of Toyota Prius trade-ins in the process. Conversely, Toyota has experienced a five-percent drop in new-Prius sales over the same period. Additionally, Ford states that it has increased its share of the US vehicle market by one percent this year, more than any full-line automaker.

Ford Explorer, Expedition next to go aluminum?

Ford made some serious waves when it unveiled the latest F-150. Instead of making its bodywork out of steel, like just about every other truck on the market, Ford went with aluminum. And you can bet the F-150 won't be the last Ford model to go with the lightweight alloy construction, either.
Our compatriots at Edmunds report that Dearborn is considering replacing two of its most popular SUVs with aluminum versions. One candidate is the Expedition, which would make sense considering that the current model (like the two preceding generations and the fullsize Bronco before it) is based on the F-150's underpinnings. Another is the Explorer, which was traditionally based on the Ranger pickup but went with a car-like unibody chassis in its current iteration. If the Explorer does go the way of aluminum, don't expect it to be a part of its very next update, which is likely due too soon for such major changes.
It would stand to reason that, if the Expedition were to go aluminum, so would the next-generation Lincoln Navigator. Ditto the MKT together with the Explorer. But those aren't likely to be the only models in contention for aluminum construction. Like any other automaker, Ford is under pressure to steadily reduce its carbon emissions and improve its fuel economy figures, prompting it to look at a whole range of measures - including more efficient engines, lower rolling-resistance tires, active aerodynamics and lightweight construction. Expect aluminum to play a big part in that equation moving forward.
