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).

2015 Ford Mustang vs. Camaro and Challenger [w/poll]

The horsepower wars are tightening among the Detroit Three, as the Ford Mustang, Chevrolet Camaro and Dodge Challenger are getting bigger, more powerful, and yes, more fuel efficient.
That came into sharper focus this week as more information was revealed about the most insane Challenger ever - the 707-horsepower Hellcat - followed quickly by Ford's in-depth showcase of the 2015 Mustang in Dearborn.
It's shaping up to be a golden age for enthusiasts, and what's under the hood is becoming more important than ever.

FBI Seizes Computers, Listening Devices From Ford Headquarters

FBI agents searched Ford Motor Company's headquarters in Dearborn, Michigan, this month as part of an investigation into possible corporate espionage. Eight devices, along with documents, computers and financial records, were among the items seized by federal agents on July 11, according to documents obtained by The Detroit News. The FBI searched Leach's home on June 20 and seized more than two dozen items in that search, Reuters reported. Former engineer Sharon Leach, a 17-year Ford veteran of company, was fired last month, according to The News, which first reported the story. She admitted to placing recording devices under conference tables before meetings. She told Ford security she used the recordings to assist in her meeting notes. She couldn't remove the devices after meetings without drawing attention to herself, leaving the devices to record other meetings. Leach has not been charged for any wrongdoing. Former federal prosecutor and Wayne State University law professor Peter Henning told The News that using a search warrant, rather than a subpoena, shows the FBI suspects more employees could be implicated. "If it's an economic espionage case or trade-secrets case, that rarely involves one individual," Henning told The Detroit News. "So the concern is if you send a subpoena and ask for recording devices, those things can be erased." Leach, Ford and the FBI declined to comment on the investigation.
