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).

2020 Toyota Highlander vs other 3-row crossovers: There can only be one!

We've done quite a few spec comparison posts involving three-row family crossovers, and when included, the Toyota Highlander has always been the runt of the group. While the rest increasingly seemed to be benchmarking each other toward greater girth, the Highlander was the outlier.  That changes a bit for the 2020 Toyota Highlander, but only a bit. It's now larger and more competitive, specifically in regards to the amount of cargo space aft of the third-row seat. As you can see below, this aligns the Highlander most closely to its long-time competitor the 2020 Honda Pilot. However, let's see how it stacks up to others in the segment, which is heavily populated now, so for the sake of space, we've selected the newest entries: Kia Telluride, Hyundai Palisade, Subaru Ascent and Ford Explorer. The order in which they are presented is random.  Performance and fuel economy The 2020 Highlander is more than 200 pounds lighter than its predecessor, but has the same 295-horsepower V6 engine that was already one of the strongest in the segment. We'd say that would give it a leg up, but the Pilot and Explorer have proven to be sprinters, delivering 0-60 times in the low-6 range by some publications' stopwatches (or VBoxes, whatever). We don't expect the Highlander to beat them, but it may dip into the 6's. The heavy, less-powerful Subaru Ascent is most likely to take up the rear. It's fuel economy of 23 mpg combined also matches the Highlander and Explorer for segment-best. Remember, however, that the Explorer's turbocharged inline-four engine is likely more susceptible to differences in driving style (read: a heavy foot).  Of course, if you're really interested in fuel economy, the Highlander and Explorer are the only vehicles in the segment to offer hybrid versions. The Ford Explorer Hybrid puts a greater emphasis on performance, however, resulting in lower estimates of 25 mpg combined (AWD) and 28 mpg combined (FWD). By contrast, the new 2020 Toyota Highlander Hybrid is estimated to return 36 mpg combined.  Passenger and cargo space According to Highlander chief engineer Yoshikazu Saeki, he had a choice of two directions with the new Highlander. He could have indeed made it bigger, matching these very competitors, especially in terms of third-row and cargo space. Or, he could have maintained a smaller-than-average size. He obviously chose the latter. First, it was the size customers had come to expect. Would they be put off by something bigger?

Ford highlights new F-650 and F-750 with full-size Tonka show truck [w/videos]

Who among us hasn't been tempted by the prospect of buying a big yellow truck and painting the name Tonka along the side? Well apparently there were some folks over at Ford who were just as tempted, only they actually had the means to make that childhood fantasy a reality in the form of the truck you see here. Revealed at the NTEA Work Truck Show this week in Indianapolis, this Tonka show truck stands nearly 10 feet tall. It's painted bright yellow, just like the one you played with in the sand box (and probably still would given the opportunity and maybe no one else looking) and has a blacked-out nose treatment and special graphics. As you can see, it's also equipped with a working dump bed, and has a truly staggering 33,000-pound gross vehicle weight rating, built to showcase the Blue Oval's new line of medium duty trucks. Of course "medium duty" is a relative term, and the new F-750 is clearly a heavier piece of machinery than the company's own Super Duty pickups, but they're lighter-duty than a proper big rig. The new 2016 Ford F-650 and F-750 are just as tough as the models they replace, but they're now quieter and more comfortable to use. In fact, Ford says its 6.7-liter Power Stroke V8 diesel is now 25-percent quieter inside the cabin at highway speeds, 45-percent quieter at idle and 35-percent quieter standing outside in front of the grille. Ford notes that it's the only medium-duty truck manufacturer that makes its own engines and transmissions. That Power Stroke diesel comes with 270 horsepower and 675 pound-feet of torque as standard, but can be upgraded to 300 hp and 700 lb-ft or all the way up to 330 hp and 725 lb-ft. Commercial buyers will also be able to choose between Regular, Super and Crew Cab models with a straight-frame, dock-height or tractor-towing frames, meaning that whatever it is you've got to haul, chances are high that the new Ford F-650 and F-750 can be set up to get the job done.
