2015 Ford F-Series Super Duty is class-leading once again

Time for everyone to feign surprise - Ford has just announced that it has the increased horsepower and torque levels of its 6.7-liter Power Stroke turbodiesel V8 engine for 2015. As you'd expect, the Blue Oval is claiming class-leading figures of 440 hp (up from 400) and 860 pound-feet (up from 800), and that's enough to enable Ford's F-450 Super Duty model to tow as much as 31,200 pounds, which, again, the automaker claims is class leading.
Now, it should be noted that the max rating quoted above is achieved with the Ford F-450. The 2015 F-350, which is perhaps a better comparison to the Ram 3500 HD pickup that claimed the towing crown in 2013 at an even 30,000 pounds, is capped at 26,500 pounds, either with a gooseneck or when towing a fifth-wheel trailer. In any case, it's going to take a load the size of Godzilla to make any of the current crop of fullsize heavy-duty pickup trucks break into a sweat. For those keeping track, Chevy rates its 2015 Silverado HD at a maximum of 23,200 pounds.
Ford's newfound pulling power comes courtesy of a larger turbocharger for its in-house Power Stroke engine, new fuel injector tips and, we'd assume, retuned computer controls. Besides the engine enhancements, the F-350 gets a wider front track for 2015 and new front springs, while the F-450 gains commercial-grade 19.5-inch wheels and tires, new rear U-joints, leaf springs, stabilizer bars and shocks. The steering and brake systems have also been upgraded.

Top Gear pits Hennessey VelociRaptor vs. Range Rover Sport SVR

As a television series, Top Gear is in limbo with an intent to return, but no hosts yet. However, it's magazine and website continue to bring us clips like this one. While the video might lack the show's charismatic hosts, this is an opportunity to see a drag race between a Land Rover Range Rover Sport SVR with 550 horsepower and a Hennessey VelociRaptor with 623 hp. The duel between these two supercharged V8s definitely sounds great. Both rugged models start at the line growling angrily at each other like dogs ready for a fight. You have to watch the clip to see whether the more powerful VelociRaptor feeds on the SVR, though.

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).
