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).

Pickup prices rising at 2x industry average

We've said it before, but bears repeating: Pickup trucks are the financial engines of America's automakers. Good thing, then, that the segment is in rude health - in fact, Automotive News is suggesting that pickup truck sales are arguably healthier than they were pre-recession, even though the segment's volume is still significantly down from where it was before the bottom fell out of the US economy. That's because per-unit profits on full-size trucks are skyrocketing, outpacing the industry's average price increases by more than double since 2005. According to data from Edmunds, the average transaction price of a full-size pickup is now $39,915 - a heady increase over the $31,059 average price in 2005 - a gain of over 8 percent after inflation is factored in.
Just how important are trucks to automakers' bottom lines? Automotive News quotes a Morgan Stanley analyst as saying the Ford F-Series is responsible for 90 percent of the company's 2012 profits, and General Motors isn't far behind, with the Chevrolet Silverado and GMC Sierra twins chipping in about two-thirds of the automaker's earnings.
Automotive News points out that Detroit's automakers now have the money to invest in modernizing their full-size truck offerings, in part because they don't have the same overhead and legacy costs that pushed General Motors and Chrysler into bankruptcy. Certainly, the pickup segment has seen a lot of innovations as of late, including turbocharged V6s, coil-spring rear suspensions and active aero. Those improvements in important areas like fuel economy and ride comfort have given existing pickup buyers new reasons to upgrade. In addition, automakers are piling on the tech and luxury goodies, creating more and more high-content, high-profit models like the Ford F-150 King Ranch, Ram 1500 Laramie Longhorn and Chevrolet Silverado High Country (shown).

Chris Harris pits Fiesta ST against Mercedes G63 AMG in 0-60 battle... sort of

Vehicle performance tests are serious business, with reputations made or broken by things like braking distance, top speed, and lateral g-forces. King of the metrics, though, is the 0-60 run, which for unknown reasons has become the benchmark for what truly makes a car a performance machine.
Now, Chris Harris from Drive has turned the whole idea behind the sprint to 60 on its ear. Taking a new Ford Fiesta ST, Harris asks a simple question: would the ST be quicker to 60 on its own, or on a trailer being towed by a Mercedes-Benz G63 AMG?
It's a fair question, really. The Fiesta Harris tested hit 60 in 7.2 seconds on a slightly uphill section of runway. It should be noted that Harris quotes his ST at 182 horsepower, which is about 15 ponies less than what we're getting in the US, so these numbers might not hold up all that well against an American model. The G63 AMG, meanwhile, is a 536-horsepower monster, powered by a twin-turbo V8 that, able to propel the big SUV to 60 mph in just 5.2 seconds without towing a Fiesta.
