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).

Ford Mustang EcoBoost has fake engine soundtrack

The 2015 Ford Mustang EcoBoost represents a huge change for the Blue Oval as the first pony car in decades to be available with a four-cylinder engine. But a recent tweet (below) from Road & Track raised our curiosity about the new vehicle. Editor Jason Cammisa pulled a fuse while driving the latest 'Stang with the 2.3-liter EcoBoost engine, and he found that both the stereo and engine went quiet in the cabin. That indicated the coupe might have some form of artificial engine sound being piped in - a feature not previously heavily reported for the model. Autoblog spoke with Ford engineer Shawn Carney who confirmed that only the turbocharged four-cylinder Mustang comes with this system, called Active Noise Control.

Ford Fiesta ST in startling track battle against Toyota GT86

On the surface, there's very little that the Ford Fiesta ST and Toyota GT86 (or the Scion FR-S that is sold in the US, or the largely similar Subaru BRZ) share in common. One is a hatchback with power coming from a turbocharged engine routed to the front wheels. The other is a coupe with power coming from a naturally aspirated four-cylinder boxer engine routed to the rear wheels.
Thing is, both of them are reasonably priced performance cars aimed at a similar segment of the automotive marketplace, so a comparison isn't out of the question. It is with all of this in mind that we direct you to the video below, in which the blokes from Evo pit the two manic little machines against one another on a race track. The result? Well, it can be summed up this way: Fast versus fun.
See how the track battle goes down in the video below.
