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).

2016 Ford Explorer First Drive [w/video]

I was still young and impressionable when Jurassic Park hit the big screen, and that movie forever imprinted the Ford Explorer in my mind. You remember the scene, but I'll describe it anyway: It's dark, raining and there's no power. The off-screen footsteps of a tyrannosaurus send shockwaves through the standing water in a plastic cup and the rain-soaked muddy roads. Seconds later, the toothy end of the movie's biggest predator crushes through the roof of a highligher-green-and-yellow Ford Explorer, causing all manner of mayhem to the SUV's occupants inside. It's not lost on me that the Ford Explorer used in the movie is, in reality, a dinosaur itself. When the seminal Explorer hit the scene in 1991 it was based on the guts of the Ranger pickup truck, which was no spring chicken itself. Ford's first real foray into the then-burgeoning SUV marketplace was meant to compete against vehicles like the Jeep Cherokee and Chevy Blazer, along with Japanese models such as the Nissan Pathfinder and Toyota 4Runner. In those early days, none of these vehicles were sold based on the merits of their car-like ride and handling or superior fuel economy. Nowadays, the discerning car shopper wants the looks of an off-road-ready SUV, but the inherent compromises and need for any serious rock-crawling capability faded away years ago. The current Ford Explorer is a prime example of this successful visual hypocrisy, with its SUV-like styling listed as the number-one reason for buying on customer surveys. SUV-like styling is one thing, SUV-like guts are another. In 2011 the Explorer went from its traditional truck-based chassis to Ford's D4 platform, based loosely on the Taurus and shared with the Flex. As with the rest of the unibody crossover world, that means the current Explorer offers an excellent ride, the higher seating position that buyers want, and a useful third row for growing families. None of that inherent family-car goodness goes away for 2016. With class-leading sales already in the bag, Ford hopes its latest Explorer will attract new buyers due to the availability of a 2.3-liter EcoBoost four-cylinder engine and an upper-crust Platinum trim level. Based on some time sitting inside and inspecting the high-content Platinum model (albeit without a drive in this trim level) I believe Ford's claim that this is most luxurious vehicle ever to wear a Blue Oval. Only not all its ovals inside are blue.

Automakers drop support for Trump effort against California emissions

WASHINGTON — Toyota, Fiat Chrysler (now known as Stellantis following its merger with Peugeot) and other major automakers said on Tuesday they were joining General Motors in abandoning support for former President Donald Trump's effort to bar California from setting its own zero emission vehicle rules. The automakers, which also included Hyundai, Kia, Mitsubishi, Mazda and Subaru, said in a joint statement they were withdrawing from an ongoing legal challenge to California's emission-setting powers, "in a gesture of good faith and to find a constructive path forward" with President Joe Biden. The automakers, along with the National Automobile Dealers Association, said they were aligned "with the Biden administrationÂ’s goals to achieve year-over-year improvements in fuel economy standards." Nissan in December withdrew from the challenge after GM's decision in November shocked the industry and won praise from Biden. On Monday, the Justice Department asked the U.S. Appeals Court for the District of Columbia to put the California emissions litigation on hold to "ensure due respect for the prerogative of the executive branch to reconsider the policy decisions of a prior administration." Biden has directed agencies to quickly reconsider TrumpÂ’s 2019 decision to revoke CaliforniaÂ’s authority to set its own auto tailpipe emissions standards and require rising numbers of zero-emission vehicles, as well as Trump's national fuel economy rollback. Asked to respond to the automakers' action, White House climate adviser Gina McCarthy said in a statement that "after four years of putting us in reverse, it is time to restart and build a sustainable future, grow domestic manufacturing, and deliver clean cars for America." California Governor Gavin Newsom praised the automakers on Twitter for "dropping your climate-denying, air-polluting, Trump-era lawsuit against CA" and urged them to join the voluntary framework. TALKS WITH BIDEN Separately, an industry trade group on Tuesday proposed to start talks with Biden on revised fuel economy standards that would be higher than Trump-era standards but lower than ones set during the prior Democratic administration. The Trump administration in March finalized a rollback of U.S. Corporate Average Fuel Economy standards to require 1.5% annual increases in efficiency through 2026, well below the 5% yearly boosts under the Obama administration rules it discarded.
