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.

Vert-A-Pac train cars kept your Chevy Vega's price in check

Our apologies to those who've seen this before, but for the rest of the class, how awesome are these pictures of the Vert-A-Pac shipping system General Motors came up with to ship the Chevrolet Vega back in the 1970s? Developed along with Southern Pacific Railroad, GM was able to double the amount of Vega models it could ship by packing them into the unique storage cars vertically.
At the time, rail cars could fit 15 vehicles each, but Chevrolet was able to lower shipping costs by making it possible to ship 30 Vegas per rail car, in turn allowing the price of the Vega to remain as low as possible. Each rail car had 30 doors that would fold down so that a Vega could be strapped on, and then a forklift would come along and lift the door into place. All the cars were positioned nose down, and since they were shipped with all of their required fluids, certain aspects had to be designed specifically for this type of shipping, including an oil baffle in the engine, a special battery and even a repositioned windshield washer reservoir. See for yourself in our image gallery above.
