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 Transit gets outfitted for prison duty

Between the Taurus-based Police Interceptor, the Explorer-based Police Interceptor Utility and the F-150 and Expedition special service vehicles, Ford has no lack of offerings for law enforcement. And now it has one more in the form of the new Transit PTV.
Based on the fullsize Transit van, the Prisoner Transport Vehicle can move as many as 12 prisoners in three separate compartments between detention facilities. Created in collaboration with Pennsylvania-based Havis Prisoner Transport Solutions and with input from Ford's Police Advisory Board, the Transit PTV takes advantage of the Transit's considerable configuration options that include three roof heights, two wheelbases, three lengths and four body-styles - not to mention engine options that include the flex-fuel 3.7-liter V6, 3.5-liter EcoBoost and 3.2-liter Power Stroke diesel.
"Transit PTV is the latest example of Ford's deep commitment to helping provide law enforcement agencies with capable vehicles. This concept proves Transit is upfit-ready and designed to Built Ford Tough standards," said Jonathan Honeycutt, Ford police marketing manager. "Many Police Advisory Board members have had the chance to drive this vehicle and they are excited about it. This new vehicle is tough, smart and efficient - ideal for the needs of law enforcement agencies."
