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.

Looking back on our favorite cars of Mad Men

The second half of the seventh and final season of Mad Men debuted this week, set to cap a run of public and critical acclaim. A decade's worth of interesting cars also made for good television, if you were paying attention. Vehicles didn't often steal the spotlight from Don, Betty, Roger, Joan and the gang, but they added meaningfully to the tone and beauty of the series. We sorted through the wheeled extras from Mad Men's archives, and choose some of our favorites to highlight. The list consists of cars that had at least a small impact on the plot of an episode, though certainly there are worthy gems hiding in just about every street and driving scene. Check out our subjective top five, and then let us know which of the Mad Men cars would be on your list. 1962 Cadillac Coupe DeVille – Season 2 Don Draper's Cadillac Coupe DeVille, all 500 feet of it, shows up in a few seasons of the show, but it's the first appearance that sets the tone. A Cadillac salesman, cut from the same cloth as Draper, asks what Don drives right now. "A Dodge," Don admits. "Those are wonderful if you want to get somewhere," allows the salesman, "this is for when you've already arrived." For a man on the move up corporate and social ladders that's a powerful message, and a pitch-perfect car. 1961 Lincoln Continental – Season 3 The most stylish Lincoln Continental ever is perfect set dressing for the mod show, of course. Though it's interesting that the car isn't cast as dapper Draper's ride, but rather his father-in-law's. Grandpa Gene does what all great grandfathers are bound to: lets his granddaughter Sally drive the big Lincoln while he works the pedals. Generational bond secured, in fine fashion. When you go back through the first three seasons of the show, you'll notice that Continentals show up more than once, too. There's nothing quite like them to evoke the best of the early '60s. 1963 John Deere 110 – Season 3 The only non-standard passenger vehicle on the list, no self-respecting gearhead/Mad Men fan should quibble with the inclusion of the John Deere 110 riding mower. For starters, the Deere is lovely to look at; a miniature version of the American Heartland icon in its green and yellow duds. The 110 appears as if milled from a solid block of steel, just the opposite of today's sleek, plasticky lawn minders (we're scouring Craigslist for one to bring home). The John Deere also has dear ramifications to the plot, too.

MotorWeek looks back at 1995 Chevy Tahoe, GMC Yukon

MotorWeek's Retro Review series gives us a nostalgic look back at some of the best sports cars and luxury sedans available in the 1980s and '90s. For its latest clip, the show shifts gears to remember the 1995 Chevrolet Tahoe and GMC Yukon. Similar to the success of crossovers today, SUVs were tallying big sales and making big money for automakers in the mid-'90s. The Tahoe and Yukon filled slots in the market as steps down from the larger Suburban. These twins weren't wanting for space, though, with plenty of room to haul around a family. MotorWeek came away generally impressed too, and called the models some "of the better riding sport utilities we've ever experienced." This review comes with some jazzy, electric guitar licks to enjoy in the background.
