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.

2013 Ford Explorer Sport

When one speaks of sporty and fun-to-drive utility vehicles, few would put the Ford Explorer in the same category as the Jeep Grand Cherokee SRT8, BMW X5 or Porsche Cayenne. Yet, with just a few reservations, I'd toss the new-for-2013 Ford Explorer Sport close to that arena for consideration.
As a recap, the sportiest of Explorers is fitted with Ford's twin-turbocharged 3.5-liter Ecoboost V6, making 365 horsepower and 350 pound feet of torque. Acceleration is brisk (figure about 7 seconds to 60 miles per hour), as power goes to all four wheels through a six-speed automatic transmission. Contributing to its more athletic demeanor are larger front brakes, a sport-tuned suspension, chassis upgrades, quicker steering ratio and a more aggressive wheel/tire package. Cosmetically, the Sport is distinguished by its blacked-out lights, black trim and noticeable lack of chrome (with the exception of the door handles).
Ford recently handed me the keys to a Ruby Red Metallic Explorer Sport. Rather than mindlessly drive the big seven-passenger all-wheel drive hauler in soccer mom circles around Los Angeles, I loaded up my family and embarked on a long weekend road trip to Yosemite National Park.

70% of pickups could use aluminum by 2025

In the next decade, the auto industry will see an explosion in its use of aluminum to cut weight and increase fuel economy, according to a study from market analysts Ducker Worldwide cited by The Detroit News. We are already seeing the lightweight metal show up extensively in luxury models from Europe, but with the impending launch of aluminum-intensive 2015 Ford F-150 (pictured above), North America is using it even more, as well. The report predicts 70 percent of US pickups to have aluminum bodies by 2025.
It won't just be pickups that see the benefit, though. The average amount of aluminum in US vehicles is forecasted by the study to grow from an average of 350 pounds in 2013 to about 550 pounds by 2025. The most common parts to use it will be hoods, doors and - to some extent - roofs, as well.
The massive increase in pickups' aluminum content hardly seems surprising. The F-150 is predicted to use so much that it might cause a short-term shortage, according to one earlier report. At the same time General Motors is heavily rumored to be negotiating with suppliers for the next generation Chevrolet Silverado and GMC Sierra. Ram is the last holdout of the Big Three, but the study predicts that not to last.
