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).

Fitting Retirement: Grand Marquis last Mercury off the line

The signs have come down and retail production ended back in October of 2010. Now, the very last Mercury model has rolled off the assembly line. This last Mercury somewhat fittingly takes the form of a Grand Marquis reporting for fleet duty. It was built at the St. Thomas plant in Ontario, Canada, which is the same facility that continues to produce the Ford Crown Victoria and Lincoln Town Car for fleet and livery duty.
St. Thomas' days are numbered, however, as the factory is slated to close on August 31. When it goes, the Panther platform is likely to follow. So long, and thanks for all the fish memories.

Ford wants smart cruise that's speed and grade sensitive

Ford is working to make adaptive cruise control even smarter and more economical for future vehicles. The automaker now has a patent (pdf link) on a system to use information on the grade of the road, traffic data, and a driver's preferences to eke out better fuel mileage over a journey. This solution would essentially put a little hypermiling right into a model's software. The Blue Oval's patent refers to this tech as "route navigation with optimal speed profile," and the system starts by splitting the way to the driver's ultimate destination into many smaller pieces. Each one is analyzed based on GPS data, and traffic info is also constantly updated. Based on the occupants' preferred travel time, all this info is combined to figure out the most efficient speed for each leg of the journey. All of these calculations are actually more than the car's computers can handle, so some of the math is offloaded to a cloud-based network. According to Ford, some of the benefits come when tackling hills while diving. Maintaining a single speed when going up and down steep grades isn't the most efficient method, but current technology can't easily make the necessary adjustments. This system uses the GPS data to adapt the vehicle's speed and leave the situation with better fuel economy. Ford is currently making major investments into autonomous driving technology and has some prestigious partners. While the patent documents don't specifically mention the optimal speed profiles for driverless vehicles, they seem like a natural fit. Over the course of an entire trip, the fuel economy gains would likely be even greater than over a few miles on a relatively flat interstate.
