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).

Buyers ditching expensive European sedans to buy expensive American trucks

The New York Times ended the automotive week with a story that adds numbers and context to a range of other stories, from the crossover craze to the increasing median price of a new car to ever more grandiose pickup trucks. The NYT piece reveals that the shift to larger vehicles isn't merely about the average U.S. buyer swapping the midsize sedan for a Ford Edge. Luxury buyers are migrating from plush sedans to plush SUVs and trucks that creep close to six-figure prices, and the Detroit Three are running Treasury presses because of it. From 2013 to 2017, the truck category — everything from pickups to minivans — climbed from 30 percent of the market to 41 percent. In January of this year, trucks claimed 66 percent of new vehicle sales. At the milk-and-honey end of profits, GMC alone accounted for 11.3 percent of all vehicle sales over $60,000, not just trucks. That puts the luxury truck maker behind Mercedes-Benz and Ford, The Blue Oval's feasting on Lariat, King Ranch and Raptor versions of the F-150, which make up more than half of that pickup's sales, putting it ahead of Chevrolet, Porsche and Lexus on the high-dollar sales list. The average transaction price of a GMC in Denali trim last year was $56,000; it's easy to see why, when one dealer told the NYT he just swapped a 2012 BMW 550i for a $71,000 GMC Sierra Denali. That truck starts at $52,900. The NYT started its story with a buyer who took home a Ford Raptor instead of an Audi A6, and optioned that $50,020 Ford Raptor close to $80,000. Over at Lincoln, the new $72,055 Navigator — the one so popular that Ford will increase production — crossed hands for an average sale price of $77,000 in January. And a Jeep dealer told the NYT that the two $93,000 Trackhawks he had on his lot "won't be here more than a few weeks." While trucks head up in sales volume and price, cars are headed so viciously in the opposite direction that "the Detroit Three and even some foreign manufacturers acknowledge they are now losing money on many of the cars they sell." So ... get ready for a lot more crossovers and trucks. Related Video: Find out what vehicle is right for you. Give our Car Finder tool a try.

Ford recalling 126,000 Fusions and Milans over wheel separation concern

Ford has announced a recall of certain Ford Fusion and Mercury Milan vehicles after an investigation by the National Highway Traffic Safety Administration. A total of 128,616 2010 and 2011 models equipped with steel wheels may have been manufactured with wheel studs that could crack and split over time. If that happens, the vehicle may experience a wheel separation.
According to The Detroit News, the company is aware of a total of 30 wheel separation incidents, one of which occurred on the front of the vehicle. Even so, no injuries have been reported as a result of the defect.
The problem apparently stems from the fact that the mounting pads on the vehicles' steel wheels may have been faulty from the factory. In addition, the wheel mounting face on rear disc brakes may not have been installed properly. Ford will inspect the rear disc face and replace them as necessary. In addition, the company will replace all of the vehicle's wheel studs free of charge. Head to the NHTSA website for more information, and click past the jump to view the full recall notice.
