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 says 70% of its models to get stop-start by 2017

Ford is following up on a report we posted a few weeks back that the Blue Oval would be adding stop-start technology to its entire model range. Now, the Dearborn-based automaker has announced that the fuel-saving feature would be available on 70 percent of the company's range by 2017.
Ford claims the technology will improve fuel economy by around 3.5 percent, although its actual effect will vary based on how the owner drives - apparently up to a 10-percent improvement is possible for those who sit in heavy traffic (Los Angelenos, this means you). The latest recipient of the technology is the updated 2014 Ford Fiesta with the company's three-cylinder EcoBoost powerplant.
Part of the reasoning for the new addition has to do with cost. Ford claims the tech is affordable and easy to implement. "Simply put, Auto Start-Stop helps customers use less fuel, which is an important component of Ford's Blueprint for Sustainability," Ford's global powertrain vice president, Bob Fascetti, said.

Ford unveils all-new 2016 F-650 and F-750 at NTEA

Medium-duty work trucks might not be the most exciting vehicles, but they perform necessary jobs everyday. Ford is in the process of a complete refresh of its entire commercial vehicle lineup over the next 18 months, and it is debuting the all-new versions of its F-650 and F-750 trucks at the NTEA Work Truck Show in Indianapolis, IN.
"The all-new F-650/F-750 allow us to leverage our strengths and sales leadership in Classes 1 to 5 to create a better F-650/F-750 that's designed, engineered and built by Ford in the USA," said Ford spokesperson Mike Levine to Autoblog via email.
Huge amounts of torque is vital for trucks like these, and both models are offered with some of Fords biggest engines. Buyers can opt for either the 6.7-liter Power Stroke V8 diesel with TorqShift 6-speed automatic with available power takeoff or a gasoline-fueled 6.8-liter V10 with a 6-speed automatic. The V10 can also be ordered from the factory to be fueled by compressed natural gas or liquid propane gas.
