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).

2018 Honda Accord charges into slumping sedan market

DETROIT - Honda on Friday revealed its newest-generation Accord, one of four re-engineered midsize sedans that Asian automakers are betting on to win market share as Detroit automakers shift focus to SUVs, crossovers, and pickup trucks. The new Accord, like rival Toyota's all-new Camry arriving this month, offers major improvements in fuel economy, technology, styling and safety. Honda declined to discuss details ahead of Friday's event in Detroit. The Accord and Camry are pillars of their manufacturers' US businesses, each selling well over 300,000 vehicles a year. In the coming months, Nissan is expected to launch a new Altima midsize sedan, and Hyundai will launch a new Sonata. Both are popular marques that will be promoted heavily. "There has been no new news on the midsize sedan side for three years, and we think this is a great opportunity to bring attention back to the segment," said Jack Hollis, Toyota's head of marketing for North America. Year to date, US passenger car sales are down 11.4 percent, and sales of midsize sedans are down 14.2 percent. Still, Americans bought 7.1 million sedans in 2016. With General Motors and Ford cutting sedan production, and Fiat Chrysler Automobiles abandoning the segment, Honda and its Asian rivals could boost sales with updated models, dealers said. "They could take share from other brands, which is traditionally what happens when a new product is launched," said Pete DeLongchamps, vice president for manufacturer relations at Group 1 Automotive Inc, the third-largest US auto dealer group. "NOT FINDING A PLACE WITH CONSUMERS" The Accord for years was Honda's top-selling model in the United States. Within the past year, US sales of the Honda CR-V have eclipsed the aging Accord, and Honda has expanded production capacity for the compact crossover. Passenger-car sales have steadily declined since 2012, when they made up 51.2 percent of the US market. Sedans have sagged to a 38.1 percent share in the first half of this year. IHS Markit said US consumer loyalty to SUVs and pickup trucks has risen since 2012, but declined for sedans. The new Accord and Camry "may stem the decline," said IHS Markit's Tom Libby. "I don't think they will cause a marked reverse." Improvements to the Accord should boost sales at Galpin Honda in San Fernando, California, general manager Ed Hartoonian said.

2024 CES Mega Photo Gallery: Honda concepts, a VinFast truck and flying cars galore

The 2024 rendition of CES is coming to a close, and per usual, it was full of all the funky, futuristic tech the show is long known for. It’s also full of cars and legitimately forward-thinking tech related to cars, and we were on the ground to see it all and bring photos to you in this Mega Gallery.  A boatload of manufacturers attended and made big reveals, from the Star Wars-like Honda concept cars to a pickup truck from VinFast, the sort of debuts we got to see ran the gamut. Of course, there were plenty of reveals and vehicles on the floor that were even more outlandish than concepts from traditional OEMs like Honda and Mercedes. Check out this flying Xpeng car as an example. Or perhaps the flying Mansory car. Apparently, flying cars were a theme. Anyway, make sure you scroll down to check out the various reveals and photos of the cars and technologies revealed at the 2024 CES in our barrage of galleries.
