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).

Bosch fined $57.8 million by DOJ for price fixing and bid rigging

The US Department of Justice has been investigating bid rigging and price fixing among automotive parts suppliers for years, and so far the agency has leveled nearly $2.5 billion in fines against 34 companies. The latest business to be caught in this ongoing crackdown is Germany's Robert Bosch GmbH (Bosch), the world's largest independent auto component maker, and it agrees to pay a $57.8 million criminal fine to the Feds. According to the DOJ, Bosch has agreed to plead guilty to pricing fixing and bid rigging for spark plugs and oxygen sensors supplied to the former DaimlerChrysler, Ford and General Motors. The rigging is said to have occurred between January 2000 and July 2011. Bosch also allegedly played foul with starter motors sold to Volkswagen from January 2009 until at least June 2010. Bosch and other companies allegedly conspired on the pricing for bids to submit to automakers, and sold the parts at noncompetitive prices. The DOJ filed a one-count felony charge in US District Court for these actions. The company's plea is still subject to court approval, though. Bosch is only the third European company to be charged in this investigation, according to the DOJ. So far, many of the fined businesses have been from Japan, including Takata, NGK and others. Some execs have claimed price-fixing has been the standard operating procedure in the auto parts industry for a long time. Robert Bosch GmbH Agrees to Plead Guilty to Price Fixing and Bid Rigging on Automobile Parts Installed in U.S. Cars Robert Bosch GmbH, the world's largest independent parts supplier to the automotive industry, based in Gerlingen, Germany, has agreed to plead guilty and to pay a $57.8 million criminal fine for its role in a conspiracy to fix prices and rig bids for spark plugs, oxygen sensors and starter motors sold to automobile and internal combustion engine manufacturers in the United States and elsewhere, the Department of Justice announced today. According to the one-count felony charge filed today in the U.S. District Court of the Eastern District of Michigan, Bosch conspired to allocate the supply of, rig bids for, and to fix, stabilize and maintain the prices of, spark plugs and oxygen sensors sold to automobile and internal combustion engine manufacturers such as DaimlerChrysler AG, Ford Motor Company, General Motors Company and Andreas Stihl AG & Co., among others, in the United States and elsewhere.

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events." View 33 Photos So we asked Sage Marie, Senior Manager of Public Relations for Honda and Acura. "If the car is stock, the warranty covers it on a track just as it does on the street. No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.
