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.

Chevy Volt sales drop in June, Nissan Leaf inches upwards

Different month, same story. That's the gist of the monthly US sales numbers from the Chevy Volt and the Nissan Leaf. These were the first two mass-market plug-in vehicles to go on sale in the US and we've been comparing their sales numbers for what seems like ages now. So far, the 2014 tale of the tape shows the all-electric once again trumping the plug-in hybrid. The last time the Volt outsold the Leaf was in October 2013. Chevrolet sold 1,777 Volts in June. That was good enough to be the Volt's best sales month of the year, but it's down 34 percent from the 2,698 units sold in June 2013. In fact, it's on par with the 1,760 Volts sold in June 2012. Given the steady sales, General Motors might need to push up the release of the next-gen Volt to gin up excitement, especially if it also offers some of the things that current Volt drivers say they want improved: more range, a lower price and a fifth seat. GM also said it sold 85 Spark EVs in June, an increase of 215 percent over June 2013 Nissan sold 2,347 Leafs last month. The good news continues for Nissan, which says it sold 2,347 Leafs last month. That's an increase of 5.5 percent over 2013 numbers and makes 2014 the best June ever for Leaf sales. Let's credit Texas. Toby Perry, Nissan's director of EV sales and marketing, said in a statement that, "Since the Texas state incentive went into effect in May, we've seen a big jump in Leaf sales in the Austin, Dallas and Houston markets. Our dealers are telling us that they saw more traffic in their stores, and they had their best Leaf sales performance in the last weekend in June." Even with that increase, Atlanta remains the top Leaf market. Nissan has sold 12,736 Leafs in the US so far this year; Chevy 8,615 Volts. Our detailed monthly sales write-up of green cars in the US, including plug-in vehicles, hybrids and diesel cars, is coming soon. For now, we invite you to discuss these numbers in the Comments.
