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).

Recharge Wrap-up: Ford announces e-bike project, Honda Accord Hybrid availability catches up

Supplies of the Honda Accord Hybrid have apparently caught up with demand. Honda originally launched the Accord Hybrid for the 2014 model year, but lack of availability plagued interested customers and eager dealers alike. Honda cited "component supply constraints" - likely batteries, electric motors and the like - for the lack of available vehicles. Now, "The supply of Accord Hybrids in general is in line with the supply of the regular Accord sedan," according to Honda's Angie Nucci. Read more at Green Car Reports. Apple is seeking a resolution to a lawsuit accusing the company of poaching employees from lithium-ion battery maker A123 Systems. A123 has requested a court order stopping a former employer from breaking an employment agreement, as well as keeping Apple from encouraging the person to do so. Apple has requested more time to respond to that court order. A123 has also filed a suit accusing five employees of breaking nondisclosure agreements and going or trying to go to work for Apple. Insiders say that Apple is developing an electric car that could go into production as early as 2020. Read more at Automotive News. South Dakota's Ethanol Infrastructure Incentive Program is helping retailers fund ethanol storage. The state government has set aside $300,000 as part of the program to fund ethanol storage tanks at gas stations. The program, which originally set out to reimburse retailers for building ethanol flex-pumps, is now helping them expand their ethanol capacities. Retailers can apply for funds for pumps and storage through June 30. Read more at Argus Leader. Ford is expanding its Global Mobility Plan with the Handle on Mobility electric bike experiment. The foldable MoDe:Me e-bike is for personal use and commuting, while the MoDe:Pro is built for commercial duty, with both powered by a 200-watt motor and 9-amp-hour battery. The bikes use an iPhone app called MoDe:Link, which provides various information and controls important bike functions. Through the app, the bikes offer navigation (with traffic data, available public transportation and charging locations included), with handlebar vibrations letting the rider know when and where to turn and automatically activating turn signals. The bike can sense and alert the rider to other vehicles on the roadway. Pedal assist is based on heart rate, allowing the rider to arrive at their destination comfortably. See the bikes in the video above, and read more from Ford.

Cadillac ELR, Nissan Resonance and Ford Atlas win Eyes on Design awards

This year's annual Eyes on Design awards were presented at the end of press days for the Detroit Auto Show on Tuesday. Given out for the best production and concept car designs that debuted at the show, and voted on by an esteemed panel of actual car designers, this year's award for best production vehicle design went to the 2014 Cadillac ELR. The 2014 Chevrolet Corvette, which was the show favorite among Autoblog editors, apparently did not impress the Eyes on Design judges enough with its all-new vent-festooned design.
The award for best concept design was actually split as a tie among the Nissan Resonance and Ford Atlas concepts. Last year's winners were the 2013 Ford Fusion and the Lexus LF-LC concept.
The Eyes on Design organization also presented a new honor this year called the Catalyst Award to Bob Lutz, former Vice Chairman of General Motors. Lutz is reported to have given a defense of design in his acceptance speech, arguing that advancements in quality across the industry as a whole have made good design a key differentiator for buyers.
