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).

Enterprise working with renter's insurance to cover $47k Mustang stolen from its lot

There was more than a bit of public indigence following the recent story of Enterprise Rent-A-Car billing a customer $47,000 to replace a Ford Mustang GT Convertible stolen from a Nova Scotia lot. To recap: Kristen Cockerill rented the Mustang for two days, returned it to the lot on a Sunday and left the keys in a secure dropbox only for Enterprise employees to find the car gone the next day.
Despite Enterprise policies stating that customers are responsible for vehicles dropped on off-days, the company has admitted that the situation could've been handled a bit better.
In a recent statement, Enterprise has backed off the big-bill story, and claims to be working with Cockerill and her insurance company to resolve the issue. Further, the Enterprise general manager overseeing Nova Scotia has spoken with the harried renter, and apologized "for the way this claim was handled during the last few months."

Ford calling in 28k Edge crossovers over fuel line leak

A problem with the fuel line on certain examples of the Ford Edge has prompted the National Highway Traffic Safety Administration to issue a recall. The issue revolves around the metal housing on the fuel line pulse damper, which was apparently improperly manufactured in the first place and is prone to crack in certain circumstances, leading to a fuel leak. And as we all know, a fuel leak is not a good thing.
The problem affects model year 2012 and 2013 Edge crossovers equipped with the 2.0-liter engine and manufactured between September 2, 2010 and April 25, 2013 - a total of 27,933 units. Although the Lincoln MKX is closely related to the Edge, since it isn't offered with the same engine (to which the problem is related), the recall does not include the premium-badged version. See the recall notice below for further details.
