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 recalling Silverado and Sierra HD diesel pickups over fuel gauge follies

General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.
The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank - it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.
GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.

United States drivers buying fewer Mexican-made cars

Crossovers and pickup trucks are not only growing in market share, they're also more profitable than cars. A crossover on the same platform as a sedan retails for thousands more, despite similar components. It's one of the reasons we've seen automakers rapidly shifting production of their sedans and hatchbacks to Mexico, where cheap labor preserves the thin profit margins on these inexpensive vehicles. But as the market continues to shift in the United States, Mexico is getting burned by its lack of product diversity. The country's auto exports, which are heavy on cars, suffered a 16-percent drop last month, Automotive News reports. In total, year-over-year exports fell from 233,515 to 197,020 last month, while year-to-date exports are down by 7.4 percent, from 922,029 to 854,118. The number one culprit? America – which usually accounts for 75 percent of Mexico's exports – and its appetite for crossovers and pickup trucks bolstered by cheap gas prices. While Mexico does build some light truck models – AN specifically calls out the Ram 2500, Honda HR-V, GMC Sierra, and Toyota Tacoma as export leaders – the vast majority of vehicles rolling out of its factories are sedans and hatchbacks. In fact, the three biggest drops in Mexican exports came from companies whose south of the border factories only build cars – Ford (Fusion/Lincoln MKZ and Fiesta), Mazda (Mazda3), and Volkswagen (Golf and Jetta). Mexican Automotive Industry Association President Eduardo Solis told AN the export shortfall will likely be sorted out sooner rather than later, thanks to a pair of new factories – a Kia car factory and an Audi SUV plant – that are coming online by year's end. The two facilities will add around 100,000 vehicles to the country's export totals, which Solis said should leave the industry on the verge of breaking another export record in 2016. But how sustainable will these record-breaking years be? Slapping an "Hecho en Mexico" sticker on a new German SUV won't be enough to change the fact that Mexico's product mix is tilted too heavily towards body styles that are not growing in volume. Mexico's record-breaking export years probably aren't at an end, but we'd argue they're certainly under threat.
