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 doubling 1.0L EcoBoost engine production

Ford's 1.0-liter EcoBoost three-cylinder engine hasn't been around that long, but it sounds like the engine is getting to be fairly popular in the automaker's global car lineup. The Detroit News is reporting that Ford has add a second shift that will allow its German engine plant to double daily output from 500 engines to 1,000.
The increased capacity is part of a plan to sell more than 300,000 vehicles a year with this engine in Europe by 2015. Europe is currently the only market where the smallest of the EcoBoost engines is offered (including in the Focus pictured above), but US-spec Fiesta models will be getting this mill for 2014.
Three-cylinder engines are expected to continue to grow in popularity in coming years with the report indicating that global production of these engines will double by 2018 to 9.8 million units. General Motors, BMW and Mitsubishi are all expected to introduce three-cylinder engines in the near term, as well.

TX officer allegedly lets 140-mph street racer go with a warning [w/poll]

Being pulled over by the police is one of the most nerve-racking situations that a driver can go through, and it's even worse when you know that the officer has you dead to rights for speeding well over the posted limit. In this video, the driver of a heavily modified Ford Mustang with a claimed 966 horsepower at the rear wheels could have easily lost his ride for doing triple-digit speeds and street racing, but a friendly Texas police officer appears to send him on his way with a simple warning.
What's more, the driver in question wasn't just speeding - his Mustang was the camera car for a bunch of rolling street races in the wee hours of the morning on a Texas highway. The driver was more than willing to mix it up in the action, too. Eventually the cops catch on and pick the 'Stang to pull over, but not before the Ford owner runs a claimed 140 mph. With only audio to go on after the car is pulled over, the police officer seems incredibly nonchalant about catching someone who was so brazenly breaking the law. Incredibly, the patrolman actually tells the driver that he's seen everyone racing tonight but ignored them. With traffic picking up, the cop says that it's time to "cut it out" and go home for the night. As far as this video shows, that was the end of it.
