NHTSA closes investigations into Ford Taurus, Hyundai Santa Fe

Ford and Hyundai are out from under the scrutinizing eyes of the National Highway Traffic Safety Administration after the government agency said it was closing investigations against both automakers over vehicle safety concerns.
Ford was being investigated for reported damaged speed control cables on Ford Taurus (shown above) and Mercury Sable models, both built between 2000 and 2003. Vehicles with the company's Duratec engines allegedly failed to allow owners to brake as expected. Owners lodged 100 complaints and were involved in five accidents, according to NHTSA records. The American automaker responded to the reports, and on June 21 of this year, said that it would inspect and repair all affected vehicles, regardless of the mileage.
Hyundai was under investigation for a reported loose fastener on the steering shaft of its 2011 Santa Fe (shown in the gallery below). After NHTSA launched its inquiry, the Korean automaker responded with its own investigation that yielded four affected vehicles. Following the inspection of 680 vehicles at its assembly plant, Hyundai said the issue was due to employee error and that no further defects have been found.

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).

Ford's first PHEV in Europe could be C-Max

Ford could start selling a plug-in hybrid in Europe pretty soon, according to at least one of its executives. Whether it's willing to do so is another story. But if the market perks up, so will the company. The automaker can "quickly" develop a plug-in hybrid version of its Mondeo, the sister car to the Ford Fusion, Automotive News Europe says, citing Ford executive Uli Koesters. The subject of Ford selling plug-in hybrids in Europe is more vital than ever since Volkswagen recently started selling its first PHEV (a Golf) there. VW will also debut a Passat PHEV next year. Koesters was less certain about whether there was sufficient European demand to warrant a production PHEV from Ford. Europe's biggest-selling plug-in hybrid through the first half of the year was the Mitsubishi Outlander PHEV. That model, according to JATO Dynamics, moved almost 9,000 units through June. Toyota sold almost 4,300 Prius Plug-in Hybrids in Europe during that time period. And we can't be sure Ford's first European PHEV will be the Modeo/Fusion, either. In fact, Ford's first plug-in hybrid for Europe is more likely to be the C-Max, John Gardiner, a Ford spokesman in Europe, told AutoblogGreen. He would only say that it would be sold "in selected markets soon," without being more specific. Ford's two PHEVs in the US have been selling well this year. Through September, sales of the Fusion Energi PHEV almost tripled to 9,323 units, while Ford C-Max Energi PHEV sales were up 51 percent to 6,486 units.
