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.

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).

Malcolm Gladwell reflects on engineering, recalls, and compromise

Journalist Malcolm Gladwell has made a career taking on big, complicated topics and humanizing them to make the unwieldy understandable. He has already done this in bestsellers like The Tipping Point and Outliers, and now he has brought the same approach to automotive recalls in a long piece for The New Yorker. The article titled The Engineer's Lament is framed around an interview with the former head of Ford's recall office about the famous Ford Pinto campaign where the position of the compact's fuel tank could cause it to explode in rear-end collisions. Plus, there are detours into Toyota's unintended acceleration cases and the General Motors ignition switch problem. While all the history is illuminating, the heart of the story comes from an examination at the thought process of engineers, and how their thinking differs from other professions. Gladwell comes off as sympathetic to auto engineers in this piece. While he admits that they often approach problems in a sterile way, the writer doesn't try point that out as a failing. It's merely a fact to be understood. The story itself is quite lengthy, but well worth a read if you have the time for an insiders view into how these recalls are assessed on the inside.
