Feds looking into Ford Explorer exhaust leak complaints

There may be a burgeoning problem with exhaust leaks in the 2011-2014 model year Ford Explorer. The National Highway Traffic Safety Administration is examining multiple complaints of a gasoline smell in the cabin of these SUVs. However, the exact cause of this problem is still unknown.
"The agency is reviewing all available data and will take appropriate action as warranted," said a NHTSA spokesperson in an email to Automotive News. Owners seem to generally complain on the regulator's website of the smell entering the cabin through the air vents. At this time, the government organization has not yet opened an official investigation into the problem, though. When it does begin inspecting vehicles, NHTSA posts a detailed breakdown of its public data online.
Similar problems have been reported about the Explorer in the past, though. In 2013, Ford issued a recall for the 2013 model year of the SUV due to a fuel leak that could cause drivers to smell a gasoline odor and repaired them again later for another possible leak. In response to Autoblog's questions, Ford responded via email: "We are not aware of a NHTSA investigation. We are currently reviewing the case and in the event that any action is required, we will address it promptly."

Aluminum lightweighting does, in fact, save fuel

When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).

Project Ugly Horse alive and kicking at Road & Track

The hallways of the Autoblog campus are much quieter now that Zach Bowman has taken his prose, along with his welders, wrenches and hammers, over to the digital pages of Road & Track, but that doesn't mean our favorite project Mustang is gone forever. Project Ugly Horse is still coming along, and Zach has gifted us another update on his unfoxy Fox Body.
Last we saw of the Ugly Horse, Zach was strengthening up the '89 Mustang's chassis as he prepares to stuff the turbocharged, direct-injected EcoBoost engine of a Ford Focus ST under the hood. First things first, the old mill must go. Head on over to Road & Track to catch the latest chapter of Project Ugly Horse.
