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 recalling 433k cars for engines that don't shut off

Ford Motor Company has announced an enormous recall affecting 433,000 vehicles built between April 2014 and June 2015. There's a problem with the body control module in the affected vehicles that can prevent them from turning off, even if the key is removed from the ignition or stop/start button has been pressed. Individual models include the Focus and C-Max, both built at the Michigan Assembly Plant. The defective Foci were built between June 17, 2014 and June 12, 2015, while the C-Maxes were built between April 22, 2014 and June 12, 2015. Also affected are model year 2015 Escape CUVs, built at the Louisville Assembly Plant in Kentucky, between April 1, 2014 and June 12, 2015. As is usually the case, the overwhelming majority of vehicles – 374,381 – are registered in the United States, while the 52,180 are in Canada and 5,135 are in Mexico. The Blue Oval is not aware of any injuries or accidents due to this defect. Individual consumers, meanwhile, will need to report into dealers to have the body control module's software updated. Scroll down for the brief press release from Ford.

In these vehicles, it could be possible for the engine to continue to run after turning the ignition key to the "off" position and removing the key, or after pressing the Engine Start/Stop button. This is a compliance issue with FMVSS 114 regarding theft protection and rollaway prevention. Ford is not aware of any accidents or injuries associated with this issue. Affected vehicles include certain 2015 Focus vehicles built at Michigan Assembly Plant from June 17, 2014, through June 12, 2015; certain 2015 C-MAX vehicles built at Michigan Assembly Plant from April 22, 2014, through June 12, 2015; and certain 2015 Escape vehicles built at Louisville Assembly Plant from April 1, 2014, through June 12, 2015. There are 432,096 vehicles in North America, including 374,781 in the United States and federalized territories, 52,180 in Canada and 5,135 in Mexico. Dealers will update the body control module software at no cost to the customer.

Goodbye Chevy Bolt, hello baby Ram and electric Chrysler 300 replacement? | Autoblog Podcast # 779

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor Jeremy Korzeniewski. They kick things off this week with some news. The Chevy Bolt and Bolt EUV will be discontinued. The McLaren 750S gets revealed and a four-door new flagship McLaren are rumored. Did Chrysler show dealers an electric 300 replacement, did we spy a new compact Ram, and are we closer to a production version of the Genesis X Convertible? Also, Greg recently visited Michigan Central Station, which Ford is revitalizing. In this week's fleet, your hosts discuss driving the Genesis Electrified GV70, Chevy Tahoe RST Performance Edition and the Polaris RZR XP.
