Ford not backing down on MPG-based marketing strategy

The Blue Oval may have to back off a bit from the green messaging. Ford has had to lower fuel-economy ratings on a number of 2013 and 2014 model-year vehicles, namely its hybrids. And that may force the US automaker to rethink some of its marketing strategy, Automotive News reports. Ford has spent much of the year pushing its fuel-efficiency improvements, with everything from a Super Bowl ad saying its Fusion Hybrid gets "almost double" the fuel efficiency of an average vehicle (after the recalculation, it's now more like 75 percent better) to claiming the Fiesta is the most fuel-efficient non-hybrid in the US (it's actually the Mitsubishi Mirage) to stating the C-Max Hybrid gets better fuel economy than the Toyota Prius V (it doesn't). Nonetheless, Ford doesn't plan on changing its mpg marketing emphasis anytime soon, the company said in an e-mailed statement to AutoblogGreen. "Providing customers great fuel economy is a key part of our Ford vehicle DNA." "Providing customers great fuel economy is a key part of our Ford vehicle DNA," the company said. "We will continue to highlight our vehicles features and attributes in our advertising and marketing, which includes fuel economy and fuel-saving technologies like EcoBoost and hybrids." Earlier this month, Ford said it would lower the fuel-economy ratings of models such as the C-Max, Fusion and Lincoln MKZ Hybrids as well as most of the Fiesta line because of mistakes in the company's internal testing data. It was the second change for the C-Max Hybrid. The good news for Ford is that its fleetwide fuel economy is up almost 40 percent from a decade ago, compared to an improvement of around 23 percent for Toyota. Still, while sales of Ford hybrids and plug-ins are about even with last year through the first five months of 2014, C-Max Hybrid sales have plunged 49 percent from a year earlier. Earlier this year, Ford admitted that the first fuel economy downgrade had a negative effect on sales and we can find proof in the numbers. Before that the change was announced, in August 2013, Ford was consistently selling over 2,000 – and sometimes over 3,000 – C-Max Hybrids a month. In September, it dropped to 1,424, then to 1,438 in October. It didn't climb back above 2,000 until May 2014. The second mpg adjustment was announced in June.

NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.

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).
