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).

Watch the Hennessey Ford GT makes its record run at Texas Mile

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.
There's not much in the video you haven't already seen, this just makes it official. That said, who doesn't want to see a twin-turbo Ford GT set an incredible speed record? You can watch it below.

John Hennessey's personal 2015 HPE700 Supercharged Ford Mustang GT hits 195 mph

Dressed in a coat of menacing black paint, the 2015 Hennessey Performance HPE700 Supercharged Ford Mustang GT definitely looks like one mean muscle machine. The 717-horsepower 'Stang proved that it can back up that aggressive appearance recently when company founder John Hennessey took his personal example to see just how fast it would go. The result down the 1.1-mile straight at the Continental Tires Proving Grounds in Uvalde, Texas, was over 195 miles per hour. The Mustang is nothing but a black blur and wall of supercharger wail as it buzzes by the camera at top speed. Despite the strong result, Hennessey doesn't seem done with the 'Stang yet. The car still seems to be pulling when it hits the rev limiter, and there's some straight track left ahead. After getting out, John Hennessey immediately says he thinks 200 mph is possible. The heart of the HPE700 is a 2.9-liter Roots-Type supercharger running at 7.25 psi. That's a pretty massive blower, especially when considering the 2.4-liter unit on the Hellcat V8. The engine also gets upgrades like improved injectors, a new fuel pump, stainless steel exhaust and recalibrated management. The company claims the upgraded Mustang can hit 60 in around 3.6 seconds and do the quarter-mile in 11.2 seconds at 131 mph. Prices for the package start at $59,500, but this one would would ring up for $65,874. Hennessey Performance is limiting production to 500 of them for the 2015 model year. 2015 HPE700 Supercharged Mustang Rockets to 195.2 mph John Hennessey takes his personal Mustang GT on a Texas road trip Uvalde, Texas-Everything is bigger in Texas, especially when it comes to automotive performance. Texas also lays claim to the highest posted speed limit in America at 85 mph. Enter the team from Hennessey Performance Engineering (HPE) who are located just west of Houston. John Hennessey and his merry band of performance car builders like to go fast, so much so that they have their own 1/4 mile dragstrip next to their workshop. Recently, the Hennessey team wanted to test their 717 horsepower HPE700 Supercharged Mustang development car (John's personal car and occasional daily driver) beyond the 130+ mph speeds that they have seen on the dragstrip. "Thankfully, we had recently received an invitation from the guys at the Continental Tires proving grounds in Uvalde to come over and do some testing on their 8.0 mile high speed oval", said Hennessey.
