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 Another 2.7 Million Vehicles In Five Separate Campaigns

The recalls keep rolling in from General Motors, evidently keen to avoid repeating the mistakes of the ignition-switch debacle and clean house. This time they're all coming at once, with five separate recalls announced together covering approximately 2.7 million vehicles. The largest of the five actions involves over 2.4 million units of the previous-generation Chevrolet Malibu and Malibu Maxx, Pontiac G6 and Saturn Aura in order to fix brake light wiring harness, which have been found to be susceptible to corrosion. The recall is separate from the 56k Aura sedans which GM recently recalled over faulty shift cables, not to mention the previous massive recall of 1.3 million vehicles – some of them the same models – but appears to have resulted from the National Highway Traffic Safety Administration investigation that started with the G6 almost a year ago. The second-largest campaign involves the 2014 Chevy Malibu, specifically those fitted with GM's 2.5-liter engine and stop/start system, approximately 140,000 examples of which has been found to have problematic brakes. The issue does not appear to be connected to the recall of 8k Malibu and Buick LaCrosse sedans (also involving brake woes) which we reported upon last week. Four crashes have been reported in such models, but GM admits it's not yet clear if the problem was a contributing factor in the accidents. A further 112k Corvette models from the 2005-2007 model years are being called in for problems with their low-beam headlamps resulting from a flexing relay control circuit wire that's not meant to bend. GM says it is "aware of several hundred complaints" about this issue, but notes that there have been no reports of related accidents. In addition, over 19k examples of Cadillac CTS from the 2013 and 2014 model years are being recalled over windshield wipers that might not work after a jump start. Finally, GM is also bringing in 477 examples of its 2014 Chevy Silverado, Tahoe and GMC Sierra (though not the Yukon) to fix a problem with a tie rod in its steering rack. As ever, all recall repairs will be performed free of charge, and GM is now estimating that recall-related actions this quarter will result in an estimated $200-million charge against its second-quarter earnings.

Best trucks for the money in 2024, according to iSeeCars

Full-size trucks are some of the most popular vehicles on the road in the U.S., but they’ve become exceedingly expensive in some cases. That makes it even more important to choose the right full-size truck to maximize value and longevity. iSeeCars recently released its list of the best trucks for the money for 2024, ranking AmericaÂ’s full-size trucks on the cost to own over 10,000 miles. Though the Ford F-150 is the best-selling new full-size truck, it failed to break into the three best trucks for the money, landing at number four on the list. The top six pickups include: Chevrolet Silverado 1500: $2,863 per 10,000 miles Toyota Tundra: $2,868 Ram 1500: $3,352 Ford F-150: $3,469 GMC Sierra 1500: $3,598 Nissan Titan: $4,008 The list is short because there is only a handful of full-size trucks on sale. Though many are expected to last quite a while – some have lifespan estimates of more than 180,000 miles, and the Toyota TundraÂ’s average life is 226,032 miles – all of them are expensive. iSeeCars found that the average new truck purchase price is $61,353, with trucks like the GMC Sierra 1500 topping $66,000. iSeeCars ranked the trucks on their purchase price and 10,000-mile ownership costs, not on driving excitement, styling, tech, or safety. It also did not asses each truckÂ’s capabilities, such as towing and payload, but said that buyers looking to save money should only purchase one if they have “genuine truck needs.” The study looked at several vehicle types to find the best models for the money in each category. The Mitsubishi Mirage was the best car overall, returning a $1,099 10,000-mile ownership cost and a low $18,991 purchase price. The Toyota Tacoma was the best midsize truck, and Toyota landed a strong seven vehicles in the top 25 best cars for the money overall. Chevrolet Ford GMC Nissan RAM Toyota
