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).

Hennessey unleashes 2015 HPE700 supercharged Ford Mustang

Thanks to the 2015 Dodge Challenger SRT Hellcat there is a new magic number in the muscle car world - 707. To raise eyebrows these days in the power war, a vehicle needs to match or preferably exceed that palindromic figure. The tuners over at Hennessey took a look at it for their 2015 HPE700 Mustang and decided to go one better. Well, ten actually, because they bestowed their latest creation with 717 horsepower and 632 pound-feet of torque.
The HPE 700 Mustang takes the standard Mustang GT with its 5.0-liter V8 and turns up the power a few hundred notches with a Roots-type supercharger running at 7.25 psi. Hennessey claims that this boosted 'Stang can rocket to 60 miles per hour in about 3.6 seconds and cover the quarter-mile in 11.2 seconds at 131 mph. For those keeping score at home, those figures are very similar to Challenger Hellcat.
To cope with all of the added boost, the engine gets a high-flow throttle body, upgraded injectors, new fuel pump, stainless steel exhaust and Hennessey's calibration for the engine management. Pricing for the package is $59,500, including the base 2015 Mustang GT, but the company is limiting production to 500 units for the 2015 model year. Founder John Hennessey told Autoblog that he has already received about a dozen orders for them.

2014 Ford Fiesta ST

Concentrated ST Formula Proves Just As Potent
I'm not the jealous type... usually. But I will fully admit to being somewhat of a Pouty Polly when I read executive editor Chris Paukert's report after driving the then-new 2013 Ford Focus ST through the impossibly pretty southern French Alps region last June. I feel like a broken record saying this yet again, but hot hatchbacks hold a special place in my heart. And while I'm always giddy to drive any sort of small, turbocharged three- or five-door at home in Detroit, my jealousy was indeed piqued after hearing Paukert tell about the challenging yet breathtaking roads he encountered while driving the flamin' yellow Focus. You know, the sort of roads that, from above, look like carelessly drizzled lines of icing on the frosted Alpen caps.
Several months later, I found myself piloting a Focus ST just west of metro Detroit, pitting it head-to-head against one of Autoblog's perennial favorite cars, the Volkswagen GTI. It was fantastic - enough so that I fully stand behind my statement that in terms of balls-out performance, the Focus ST cannot be beat as far as today's front-wheel-drive hatches are concerned.
