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).

For EV drivers, realities may dampen the electric elation

The Atlantic, a decades-old monthly journal well-regarded for its intelligent essays on international news, American politics and cultural happenings, recently turned its attention to the car world. A piece that ran in The Atlantic in October examined the excesses of the GMC Hummer EV for compromising safety. And now in its latest edition, the magazine ran a compelling story about the challenges of driving an electric vehicle and how those experiences “mythologize the car as the great equalizer.” Titled “The Inconvenient Truth About Electric Vehicles,” the story addresses the economics of EVs, the stresses related to range anxiety, the social effects of owning an electric car — as in, affording one — and the overarching need for places to recharge that car. Basically, author Andrew Moseman says that EV life isn't so rosy: “On the eve of the long-promised electric-vehicle revolution, the myth is due for an update. Americans who take the plunge and buy their first EV will find a lot to love Â… they may also find that electric-vehicle ownership upends notions about driving, cost, and freedom, including how much car your money can buy. "No one spends an extra $5,000 to get a bigger gas tank in a Honda Civic, but with an EV, economic status is suddenly more connected to how much of the world you get to see — and how stressed out or annoyed youÂ’ll feel along the way.” Moseman charts how a basic Ford F-150 Lightning electric truck might start at $55,000, but an extended-range battery, which stretches the distance on a charge from 230 miles to 320, “raises the cost to at least $80,000. The trend holds true with all-electric brands such as Tesla, Rivian, and Lucid, and for many electric offerings from legacy automakers. The bigger battery option can add a four- or five-figure bump to an already accelerating sticker price.” As for the charging issue, the author details his anxiety driving a Telsa in Death Valley, with no charging stations in sight. “For those who never leave the comfort of the city, these concerns sound negligible," he says. "But so many of us want our cars to do everything, go everywhere, ferry us to the boundless life we imagine (or the one weÂ’re promised in car commercials),” he writes. His conclusions may raise some hackles among those of us who value automotive independence — not to mention fun — over practicalities.

2013 Shelby 1000 unleashes its 1,200 horsepower ahead of NY show reveal

True story: Last fall, I had the opportunity to spend a week with Ford's new 2013 Shelby GT500 - the Blue Oval's factory Mustang with 662 horsepower and 631 pound-feet of torque. It's an amazing beast, to be sure. I'm not sure if it was Michigan's damp streets strewn with potholes and wet leaves, but at no point did I ever say to myself, "You know, Ford is on to a really good thing here, but what it really needs is about twice the power." And yet, for people in warmer climes with infrastructure in better nick - or for those whose muscle cars live their lives out on the track, there's apparently sufficient demand to warrant just such a beast.
Quick studies will recall that Shelby American launched its 1000 last year to commemorate its 50th anniversary, but it is returning to the New York Auto Show with a fresh version based on the 2013 GT500 I drove. The 2013 Shelby 1000 whips up 1,200 horsepower on pump gas thanks to beefed-up forced induction, engine internals and cooling. Wisely, it also incorporates an adjustable suspension and big brake package to make sure those ponies have the best chance being safely deployed to the ground.
What price the world's most powerful "production" muscle car? $154,995 for starters - donor GT500 not included. What, no convertible variant?
