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).

China-market Ford Edge spotted testing in Spain with a mystery wagon

There are a few threads to put together for this one. The U.S.-market Ford Edge and Lincoln Nautilus have been rumored to meet their ends during the 2023 model year; contract negotiations pointed to the Oakville Assembly Plant that that builds being converted to build five Ford electric vehicles in 2025. On top of that, we've heard years of rumors about a Ford Fusion Active wagon-esque product that would challenge the Subaru Outback and fill a perceived gap in the U.S. lineup. We're not sure what the Ford vehicles in the spy shots above are, nor were the spy photographers who caught them during hot weather testing in Spain. And we mean vehicles, plural, details like the side mirror attachment points, DRL signatures, rear bumpers and muffler orientations pointing to these being two products. Here are our guesses. One of them is almost certainly the new Ford Edge that will debut soon for the Chinese market (above and below). Motor1 saw that the Chinese Ministry of Industry and Information Technology published photos of that country's newest Edge in two configurations, a lesser trim that can seat five or seven, and a top trim that seats seven only. The camouflaged car in the gallery above with the mirrors that mount on the door would be the same vehicle. The headlights on the China-market Edge feature the same central, stacked DRLs instead of the single lower and side DRLs of the other vehicle. The taillights are temporary units, but they match the squared vertical design of the new crossover. And the rear bumper of the Chinese Edge features the same slanted cutout in the middle, and beneath that, the same enormous muffler on the driver's side of the car. Look more closely, and one can also spot the way the sheetmetal flicks up at the C-pillar then descends to the D-pillar. Engineers tried to hide it with camo, but it's there. Ford Authority believes the other vehicle, the one with the side mirrors mounted at the base of the A-pillar, could be a new Lincoln Nautilus. Ford's Changan Hangzhou plant in China builds the Edge and its sister Lincoln product for that market. Although both are presumed to be headed for the grave here, one is clearly carrying on over there, so there's no reason to believe the other wouldn't as well.       The big mystery is whether one of these is the Ford Fusion Active. Well, a bigger mystery would be to figure out if the Fusion Active is even a thing anymore, or if we — including Ford — collectively imagined it.

Takata adds millions to recall expansion in US [UPDATE]

UPDATE: Ford spokesperson Kelli Felker has advised Autoblog that of the 1,509,535 total vehicles worldwide that the company is recalling, 966,504 of them are new additions for this expanded safety campaign. Last week, the National Highway Traffic Safety Administration announced that the Takata airbag inflator recalls would expand to an estimated 33.8 million vehicles in the US. However at the time, automakers weren't sure specifically which of their models might be affected under this enlarged campaign. Now, the numbers for BMW, FCA, Ford, and Mitsubishi are being released by the agency. Additionally, Honda is outlining the broadening of its own campaign. BMW's recall amounts to 420,661 vehicles in the US, an increase from 140,696 previously. All of the following models need their front, driver's side airbag replaced: 2002-2005 BMW 325i/325xi/330i/330xi Sedan 2002-2005 BMW 325xi/325i Sportswagon 2002-2006 BMW 330Ci/325Ci/M3 Convertible 2002-2006 BMW 325i/330i/M3 Coupe 2002-2003 BMW M5/540i/525i/530i Sedan 2002-2003 BMW 540i/525i Sportswagon 2003-2004 BMW X5 3.0i/4.4i BMW has received no reports of any injures or deaths from this problem in its vehicles. FCA has 5,224,845 vehicles globally in need of inflator replacements, according to its statement. However, the company is only aware of one injury related to the issue, which occurred in a 2006 Dodge Charger in southern Florida. There are 4,747,202 vehicles worldwide from the company that are affected on the front, driver's side. Among these, 4,066,732 are in the US, 374,508 are in Canada, and the rest are in other countries. The models are: 2005-2009 Dodge Ram 2500 Pickup 2004-2008 Dodge Ram 1500 Pickup 2006-2009 Dodge Ram 3500 Pickup 2007-2009 Dodge Ram 3500 Cab Chassis 2008-2010 Dodge Ram 4500/5500 Cab Chassis 2008-2009 Sterling 4500/5500 Cab Chassis 2004-2008 Dodge Durango 2007-2008 Chrysler Aspen 2005-2010 Chrysler 300/300C/SRT8 2005-2010 Dodge Charger/Magnum 2005-2011 Dodge Dakota 2006-2010 Mitsubishi Raider Also, there are 438,156 vehicles in the US, according to the NHTSA documents, that need their front passenger's side inflators replaced in the expansion of an earlier regional recall: 2003 Dodge Ram 1500 2003 Dodge Ram 2500 2003 Dodge Ram 3500 The total number of vehicles from Ford now covered under these campaigns stands at 1,509,535 worldwide. Of this total, there are 1,380,604 in the United States, 93,207 in Canada and 16,953 in Mexico.
