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).

Autoblog Technology of the Year Award Special | Autoblog Podcast #758

This episode of the Autoblog Podcast features Editor-in-Chief Greg Migliore, Road Test Editor Zac Palmer and Consumer Editor Jeremy Korzeniewski. The trio begin by discussing the 2022 Technology of the Year award. Ford's Onboard Scales and Smart Hitch hauling/towing tech as tested in the F-150 Lightning won this year. Why the Ford won, how testing went down and Ford's competition — including the GMC Hummer EV and Genesis GV60 — are discussed. After diving through the Technology of the Year award testing, the three take on this week's news. A mysterious vehicle based on the Corvette (that isn't a Corvette) is supposedly on its way. Audi is giving us "Performance" versions of the RS 6 Avant and RS 7 Sportback. Plus, we discuss a recent study that provides data for the 10 longest lasting vehicles on the road today. After the news, the crew dive into the cars they've been driving this week. Greg's been behind the wheel of a Nissan Pathfinder, while Jeremy and Zac have been driving some plug-in hybrids, including the Lexus NX 450h+ and Autoblog's long-term BMW 330e xDrive.

Average transaction prices climb to a record $36,270 in January

The automotive sector made a hash of the numbers last month, a mess of pluses and minuses clogging the transaction-price charts according to Kelley Blue Book. The overall industry rose one percent, even though buyers bought fewer cars and light vehicles in January 2018 vs 2017 using the selling-day adjusted rate. Due to January transaction prices rising to $36,270, a record for January, the value of new vehicles sold climbed more than $1 billion compared to January 2017. KBB's transaction prices don't include customer incentives, which changes the complexion slightly; average incentive spending rose to just over ten percent. The average transaction price in December 2017 was $36,756, so January dropped a bit - nothing unexpected, with the month annually blamed for "January doldrums." More revealing is the fact that the average transaction price in January 2017 was $34,910. This year's plumped-up figure came courtesy of the continued shift to crossovers, SUVs, and light trucks, which shouldn't surprise anyone who's read an automotive blog in the past 20 years. That category comprised nearly 70 percent of new vehicle sales for the month. Some manufacturers profited more than others, though. Fiat Chrysler managed 12.8 percent fewer sales in January compared year-on-year, but the company's vehicles sold for $1,300 more. The Ford brand suffered a 6.3-percent dip in sales, but brand transaction prices increased $2,000, while a Lincoln sold for $8,700 more on average. General Motors sold more cars and sold them for more money; overall GM transaction prices rose four percent, or $1,270, while a GMC traded hands for seven-percent more than in January 2017 and a Cadillac got $2,300 more on average. Of KBB's listed automakers, the Volkswagen Group got the most of out its customers, transaction prices rising at the German automaker by 5.6 percent to $42,243 in January 2018 compared to a year earlier. American Honda followed with a 4.3-percent increase to $28,991, GM in third at 4.1 percent to $40,313. Find your next car at Autoblog using our new and used car listings or the Car Finder tool. Broken out by segment, minivans rocked the table, transaction prices leaping by 7.9 percent to $35,380 compared to January a year earlier. Luxury cars boasted the next-highest rise, at 3.6 percent to $58,533.
