Expert: 54.5 mpg CAFE standard can be reached without many plug-ins

Johnson Controls executive Brian Kesseler isn't likely to get any holiday presents this year from Nissan chief Carlos Ghosn or Tesla Motors head Elon Musk, but lots of other folks might be happy with what he has to say about automakers' efforts to reach stricter fleetwide fuel-economy standards. Speaking at the Automotive News World Congress, Kesseler said automakers wouldn't need to sell an extensive number of plug-in vehicles in order to meet the 54.5 mile per gallon Corporate Average Fuel Economy (CAFE) standard the US government set in 2012 for 2025 model-year vehicles. In fact, he said, components such as stop-start engine technology, turbochargers and direct injection may actually do the trick. Already, things like smaller engine sizes and lighter cars are already playing major roles in spurring fuel-efficiency gains. Of course, Johnson Controls sells batteries specially built for stop-start systems, so Kesseler does have a bit of skin in this game. The 54.5-mpg CAFE standard equates to about a 40-mpg "real world" fuel-efficiency level. To put that into perspective, the Environmental Protection Agency (EPA) said in a report late last year that model-year 2013 average fuel economy was an even 24 mpg. That was up from 23.6 mpg for the 2012 model year and 22.4 mpg for 2011.

Toyota Camry, Honda Civic inventories mounting as US automakers make inroads

Two of the hottest-selling cars in America aren't quite as hot as they used to be. The Toyota Camry and Honda Civic are both seeing dealer supplies increase in the face of renewed competition from the much-improved Detroit Three.
According to a report from The Detroit News, the Camry's dealer inventory is 15 days higher than its seasonal average, while the Civic is 25 days above average. Things aren't expected to get better for Toyota and Honda, as RBC Capital Markets analyst Joseph Spak marked the two Japanese offerings as "at risk for reduced output."
The Detroit Three, meanwhile, are seeing supplies dwindle as demand increases, especially for the Ford Fusion, which has seen an 18-percent increase in 2013 sales, and the Chevrolet Cruze, which was second only to the Camry in June 2013 sales.

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).
