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).

Motor Trend pits Camaro 1LE vs Mustang with Performance Pack, surprises ensue

With the 2015 Ford Mustang firmly on the scene, the inevitable comparisons with its arch rival, the 2015 Chevrolet Camaro are just starting to trickle out. Over the next several months, you're likely to be inundated by every outlet's muscle car comparison, whether it be the turbocharged Ford against the V6 Chevy, a V8-powered convertible comparo or what we have here, a competition between each vehicle's performance upgrade.
Motor Trend has pitted the Camaro SS 1LE against a Mustang with the GT Performance Pack for a comprehensive series of comparisons on the test stage, street and finally, at Willow Springs with ace Randy Pobst behind the wheel. As per usual, we aren't about to spoil this one for you.

Are we about to see a real SUV revival?

Now that the marketplace has been oversaturated with cute-utes, crossovers, and CUV coupes, are we about to see a resurgence of real, honest-to-God SUVs? Ummm... maybe. The stars seem to be aligning in that direction, at least that's the sense I'm getting. We know an all-new Jeep Wrangler is only a few auto shows away; and that Jeep is about to introduce a new Grand Cherokee Trailhawk for 2017, in the same rugged spirit of the successful Cherokee and Renegade Trailhawks. Ford has hinted at a neo-Bronco, after showing the concept above in 2014 to wet the mouths of all those Duck Dynasty-types out there. And, and... wait for it... I recently learned that Subaru sent a questionnaire out to some Forester owners asking if they might be interested in an off-road package if it were offered. The items listed were pretty hardcore, serious stuff, such as: integrated tow/recovery hooks, additional ground clearance, more rugged wheels, skid plates, altimeter, front-view off-road camera, improved approach and departure angles, advanced differentials, Inclinometer, full-size spare tire, upgraded off-road suspension components, more aggressive tires, off-road driving mode (engine, transmission, throttle, and steering settings), more rugged styling, low-range gearing, and a more advanced traction management system. Folks that's not my wish list (well, actually it is), but those are words from Subaru, asking if that's what customers would like to see. Need proof? Go to the SubaruForester.org website. It's in a discussion there. So... no promises or guarantees here, and feel free to call me a rumormonger if you like; but the next few years could prove very interesting for those who actually do go off road. If this pans out, remember, you read it here first. Related Video: Image Credit: Ford Ford Jeep Subaru Crossover SUV Off-Road Vehicles open road
