GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

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).

Trump wants a trade deal, but South Korea doesn't want US cars

SEOUL - US auto imports from the likes of General Motors and Ford must become more chic, affordable or fuel-efficient to reap the rewards of President Donald Trump's attempts to renegotiate a trade deal with key ally South Korea, officials and industry experts in Seoul say. Meeting South Korean President Moon Jae-in last week in Washington, Trump said the United States would do more to address trade imbalances with South Korea and create "a fair shake" to sell more cars there, the world's 11th largest auto market. "What we really want to say to the United States is: Make good cars, make cars that Korean consumers like." While imports from automakers including Ford, Chrysler and GM more than doubled last year largely thanks to free trade deal which took effect in 2012, sales account for just 1 percent of a market dominated by more affordable models from local giants Hyundai and affiliate Kia. Imports make up just 15 percent of the overall Korean auto market, and are mainly more luxurious models from German automakers BMW and Daimler AG's Mercedes-Benz, which also benefit from a trade deal with the European Union. "Addressing non-tariff barriers would not fundamentally raise the competitiveness of US cars," a senior Korean government official told Reuters, declining to be identified because of the sensitivity of the subject. "What we really want to say to the United States is: Make good cars, make cars that Korean consumers like." TASTE BARRIER In Korea, US imports are seen as lagging German brands in brand image, sophistication and fuel economy, industry experts say. US imports do have a competitive advantage in electric cars: Tesla Motors' electric vehicles are seen as both environmentally friendly and trendy, while GM has launched a long-range Bolt EV. US Commerce Secretary Wilbur Ross had cited a quota in the current trade deal as an obstacle to boosting imports. The quota allows US automakers to bring in each year 25,000 vehicles that meet US, not necessarily Korean, safety standards. Should GM, for example, decide to bring in more than its quota of one model - the Impala sedans - it would cost up to $75 million to modify the cars to meet Korean safety standards, the company told its local labor union. Asked about non-tariff barriers, a spokesman at GM's Korean unit said removing them could expand the range of models the company can bring in from the United States. No US company, however, has yet to make full use of the quota, industry data shows.
