Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.

GM recalls 64k 2011-2013 Volts over carbon monoxide fears, stop sale on Trax and Encore

General Motors is recalling 50,249 Chevrolet Volts from the 2011-2013 model years in the US and an additional 13,937 exported examples because of fears over carbon monoxide buildup. According to a statement, if a Volt is accidentally left on while running on electric power, its internal combustion engine would eventually kick on to charge on the battery. If this happens in an enclosed space, then carbon monoxide can fill the area, leading to a potential exposure to the dangerous gas. According to GM, there have been two injuries reported due to this issue. To fix the problem, there's a software update to limit the time the vehicle can idle. According to Automotive News, GM is also issuing a stop sale on about 2,300 examples of the 2015 Chevrolet Trax and Buick Encore. In these compact crossovers, it's possible that the steering column assembly could touch the power steering circuit board and cause damage over time. This could potentially cause the system to stop working. Automotive News indicates that the automaker is still working with the supplier to get the necessary parts to repair this problem. General Motors is recalling 50,249 Chevrolet Volts in the U.S. from the 2011-2013 model years to implement a software update that will limit the amount of time a vehicle can be left idling in the "on" or "run" position. If a driver exits the vehicle and inadvertently leaves the vehicle "on" by failing to react to cues and warning chimes emitted by the vehicle, the vehicle's high-voltage battery will drain after a period of time and the gasoline engine will begin to run. If the gas engine runs for a long period of time within an enclosed space, such as a garage, carbon monoxide could build up. GM is aware of two injuries, both related to carbon monoxide build up. The total recall population including Canada and exports is 64,186. Related Video:
