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).

Lincoln Continental production likely to shift to Flat Rock

Lincoln production may be returning to Michigan, according to a new report from Automotive News. While the brand's current big sedan, the MKS, is built alongside the Ford Taurus, Ford Explorer, and their Police Interceptor counterparts at the Blue Oval's Chicago, IL factory, the production version of the Continental won't be screwed together in the Windy City. According to AN, "industry sources" claim the Continental will join the Ford Mustang and Ford Fusion – on which the big Lincoln is loosely based – at the company's Flat Rock, MI factory. The move isn't just based on convenience, though. Ford is selling a lot of Explorers, and shifting Lincoln production away from Chicago Assembly frees up production capacity for the popular SUV. "Chicago Assembly Plant is vital to our global manufacturing footprint and will continue to manufacture the Ford Taurus, Ford Explorer and Police Interceptor vehicles even after we phase out production of the MKS in 2016," Ford told Automotive News. "We will continue to match production to demand." Looking at the numbers further backs up the argument against Lincoln production in Chicago. Last year alone, Ford built nearly 285,000 Explorers and over 73,000 Taurus sedans, compared to just 8,300 Lincolns. Finally, as AN tells it, Ford is almost telegraphing the Continental's arrival in Flat Rock. The facility has a four-week shut down scheduled from June 15 through July 13, which is twice as long as the typical summer vacation, while there's another two weeks off slated for September.
