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).

2015 Ford F-150 to get 2.7-liter EcoBoost?

As we prepare for the arrival of the all-new, next-generation Ford F-150, rumors about the new truck are picking up steam. Naturally, many of said rumors aren't just related to the way the truck will look (it's expected to take design cues from the Atlas concept shown above), they're tied to what's going to motivate the Blue Oval mainstay, with Ford's EcoBoost range likely to play an increasingly key role. While we're still expecting the current 3.5-liter, twin-turbocharged V6 to retain its position as a premium alternative to Ford's naturally aspirated V6 and V8, a Canadian automotive news site is proposing that the Dearborn automaker is also preparing a new, more fuel-efficient downsized EcoBoost option.
Autos.ca is reporting that a new, 2.7-liter, twin-turbocharged V6 could find its way into the lighter, aluminum-intensive truck. The new engine supposedly makes use of asymmetrical turbos to generate 320 horsepower and 370 pound-feet of torque - substantially more impressive numbers than the current 3.7-liter base engine's 302 ponies and 278 lb-ft - while offering improved fuel economy and emissions. The new 2.7 EcoBoost (internally dubbed "Nano") isn't expected to supplant the naturally aspirated V6 as the F-150's base engine, it's expected to slot in above directly it.
Naturally, we're prescribing more than a few grains of salt to go with these rumors, at least until Ford debuts the next F-150 at the 2014 Detroit Auto Show, a reveal we'll be covering in a mere two weeks.

Our love of SUVs is killing people in the streets

Americans are fond of supersized fast-food meals and colossal convenience-store fountain drinks, even though they're clearly bad for our health and U.S. adults keep getting fatter. We also like large vehicles, and our love affair with SUVs is killing people in the streets. According to a recent investigation by the Detroit Free Press/USA Today, the increase in SUV sales over the past several years coincides with a sharp rise in pedestrian deaths in the U.S. — up 46 percent since 2009, with nearly 6,000 people killed in 2016 alone. With SUV sales surpassing sedans in 2014 and pickups and SUVs currently accounting for 60 percent of new vehicle sales, it's no wonder Ford announced in April plans to cease U.S. sales of almost all passenger cars. And this followed Fiat Chrysler's move to virtually an all-truck, -SUV and -crossover lineup. While the Freep/USA Today investigation found that the simultaneous surge in SUV sales and pedestrian deaths comes down to vehicle size, it also points to a lack of action on the part of the National Highway Traffic Safety Administration (NHTSA), even though it knew of the dangers SUVs pose to pedestrians. Also blamed are automakers dragging their feet on implementing active safety features. Using federal accident data, the Insurance Institute for Highway Safety (IIHS) determined that there was an 81 percent increase in single-vehicle pedestrian fatalities involving SUVs between 2009 and 2016. Freep/USA Today's analysis of the same data by counting vehicles that struck and killed pedestrians instead of the number of people killed showed a 69 percent increase in SUV involvement. As far back as 2001, researchers at Rowan University forecasted a rise in pedestrian deaths as Americans began switching to SUVs. "In the United States, passenger vehicles are shifting from a fleet populated primarily by cars to a fleet dominated by light trucks and vans," the researchers wrote, with light trucks comprising SUVs.
