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 tops GM in US vehicle sales in May, driven by fleets

DETROIT - Ford, bolstered by heavy sales to fleet customers, surpassed General Motors in US new vehicle sales in May, according to figures reported Thursday. Ford said May sales rose 2.2 percent from a year ago to 241,126 units. GM sales dropped 1.3 percent to 237,364. GM said it had been trimming sales of heavily discounted vehicles to car rental companies. Such fleet sales made up about 19 percent of its total sales in May. Ford's fleet sales rose 8.4 percent, representing more than 34 percent of total sales. The industry average is around 20 percent. Analysts had expected mixed results for the industry, with sales likely propped up by heavy discounts. Fiat Chrysler Automobiles said May sales dipped 0.9 percent to 193,040. Toyota's US sales dropped 0.5 percent to 218,248. Nissan said US sales in May rose 3.0 percent, to 137,471. After demand fell in March and April, analysts estimated May sales at just over 1.5 million. The seasonally adjusted annual rate of sales in May was estimated at 16.8 million to 16.9 million vehicles, about the same as April. A year earlier, sales stood at 17.55 million vehicles. Early reports indicated that sales over the three-day Memorial Day weekend were helped by heavy discounts. "While demand for new vehicles is still relatively strong, it's a bit of smoke and mirrors," said Jessica Caldwell, executive director of industry analysis at Edmunds, the car shopping website. Manufacturers and dealers "really pushed the deals over the holiday weekend to prop up their May numbers," she said. "Incentives were up sharply, and it seems automakers are putting more cash on the hood to nudge car shoppers to buy versus lease." General Motors dealers were offering discounts of up to $12,000 on the full-size Chevrolet Silverado pickup, while some dealer discounts on Ford Motor Co's F-series pickups were more than $10,000 on 2017 models and more than $14,000 on leftover 2016 models. The 2017 model year started eight months ago. Reporting by Paul LienertRelated Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

2015 Ford Focus

Sitting down at the pre-drive briefing with Ford engineers ahead of sampling the refreshed 2015 Focus, water bottles clinked as we wet our whistles before Q&A. While pouring a glass, we noticed something stamped on the bottle label: "1L." One liter. We were palming the exact displacement of the EcoBoost engine our group was about to drive. This was undoubtedly coincidence (such bottles litter every conference and dinner table in Europe) but it served to drive home just how small the total swept volume of Ford's wunderkind powerplant really is. It's tiny.
Of course, this isn't our first run-in with the little triple - we've sampled its turbocharged charms before in Ford's smaller Fiesta. At that time, we found it had plenty of poke for the subcompact, but the larger C-segment Focus carries around another 450 pounds or so and pushes a wider profile through the air. Would the three-cylinder have the stuffing to make the most of the Focus' athletic chassis, or would it be a letdown? Would it be the same as it was when we tested it in a Euro-spec Focus a couple of years ago? There was nothing left for it but to head out on the bucolic roads surrounding Versailles the day after the Paris Motor Show and find out for ourselves.
