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).

James May picks 13 most significant cars ever for London Classic Car Show

James May tends to be the most pragmatic of the Top Gear UK hosting crew. Jeremy Clarkson obviously likes his vehicles loud, brash and preferably British, and Richard Hammond seems to have a thing for American muscle. May appears to find joy just in the mechanical nature of things, whether high performance or simply made for getting around. He's getting a chance to put that appreciation on display by curating a 13-car collection at the London Classic Car Show called The Cars That Changed The World. May actually wants to provoke debate from visitors about the exhibit and is separating his choices into two categories: The Halls of Obviousness and The Chambers of Bloody-mindedness. The first bunch includes the usual important vehicles you expect to see, but the other group has the really interesting picks. As May explains these selections in the event announcement, "I believe they are just as significant historically but they've simply been forgotten or misunderstood." The obvious choices are: 1886 Benz Motorwagen 1908 Ford Model T 1938 Volkswagen Beetle 1959 Austin Mini 1964 Ford Mustang 1997 Toyota Prius And the more eccentric ones are: 1901 Waverley Electric 1906 Cadillac Model K 1933 Standard Superior 1972 Honda Civic 1980 Lada Riva 2009 Bruno ExoMars Rover If you notice, there are only 12 vehicles listed above. That's because the final one is being kept secret for show attendees, but May considers it the most significant car ever made. The London Classic Car Show runs at the ExCeL in London's Docklands from January 8-11, 2015. In addition to May's exhibit and the other vehicles there, Formula 1 designer Adrian Newey is also curating a display from his own collection. May is hoping to spur conversations with his choices. Let us know in Comments if you notice any glaring omissions that should be among the 13. Read the full announcement below, along with a brief explanation for each choice from May. GET READY FOR A CLASSIC ARGUMENT 30/12/14 James May has chosen the 13 most significant cars of all time for The London Classic Car Show... but is he right? It's bold, controversial and bound to cause arguments... and that's just the way BBC Top Gear's James May wants it. May has stuck his neck on the line and has chosen what he regards are the 13 most influential cars of all time. The result is The Cars That Changed The World and it's one of the star exhibits at the London Classic Car Show taking place at ExCeL in London's Docklands from 8-11 January 2015.

Ford fights back against patent trolls

Some people are just awful. Some organizations are just as awful. And when those people join those organizations, we get stories like this one, where Ford has spent the past several years combatting so-called patent trolls. According to Automotive News, these malicious organizations have filed over a dozen lawsuits against the company since 2012. They work by purchasing patents, only to later accuse companies of misusing intellectual property, despite the fact that the so-called patent assertion companies never actually, you know, do anything with said intellectual property. AN reports that both Hyundai and Toyota have been victimized by these companies, with the former forced to pay $11.5 million to a company called Clear With Computers. Toyota, meanwhile, settled with Paice LLC, over its hybrid tech. The world's largest automaker agreed to pay $5 million, on top of $98 for every hybrid it sold (if the terms of the deal included each of the roughly 1.5 million hybrids Toyota sold since 2000, the company would have owed $147 million). Including the previous couple of examples, AN reports 107 suits were filed against automakers last year alone. But Ford is taking action to prevent further troubles... kind of. The company has signed on with a firm called RPX, in what sounds strangely like a protection racket. Automakers like Ford pay RPX around $1.5 million each year for access to its catalog of patents, which it spent nearly $1 billion building. "We take the protection and licensing of patented innovations very seriously," Ford told AN via email. "And as many smart businesses are doing, we are taking proactive steps to protect against those seeking patent infringement litigation." What are your thoughts on this? Should this patent business be better managed? Is it reasonable that companies purchase patents only to file suit against the companies that build actual products? Have your say in Comments.
