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.

Engine block heater issues force GM to recall 324,226 diesel heavy duty trucks

General Motors has issued a recall on 324,226 diesel heavy duty trucks that could be susceptible to short circuits, and consequently, potential fire. The recall affects several models of heavy duty Chevrolet Silverados and GMC Sierras with optional engine block heaters. GM is recalling seven different truck models spread across three years. The recall affects the 2017-2019 Chevrolet Silverado 2500HD, 2017-2019 Silverado 3500HD, 2019 Silverado 4500HD, 2019 Silverado 5500HD, and 2019 Silverado 6500HD, plus the 2017-2019 GMC Sierra 2500HD and 2017-2019 Sierra 3500HD. Specifically, it includes these models with the 6.6-liter Duramax diesel engines and the optional engine block heater. The recall technically deals not with the engine block heater itself, but the way it is connected. According to NHTSA campaign No. 19V328000, the engine block heater cord or the terminals that link the cord to the heater could short circuit. A short circuit could potentially damage engine components and result in a fire. According to The Detroit News, 19 fires have been reported but nobody has been injured. GM has yet to figure out a fix, and thus has not yet released a notification schedule for affected customers. If you believe your vehicle is part of the recall, contact GM customer service at 1-586-596-1733 and use reference number N182206310.

More than 5,500 people tried to get the 2016 Chevy COPO Camaro

It's stating the obvious, but the 2016 Chevy COPO Camaro is popular with enthusiasts. So much so, it's attracted more than 5,500 hand raisers, General Motors said Tuesday at an event to show off the company's new Performance and Racing Center in Pontiac, MI. Unfortunately for drag racing fans, Chevy will only sell 69 of them, as it has for the last four years. The COPO Camaro can be configured for the NHRA Stock and Super Stock classes. It comes with racing-tuned chassis pieces and a solid rear axle. Power choices include 5.7-, 6.2- and 7.0-liter V8 engines. About half of COPO Camaro owners race their cars, and the rest keep them as collectibles. Jim Campbell, GM vice president of Performance Vehicles and Motorsports, wouldn't say if the COPO is a profitable venture, but noted the fire-breathing dragster raises the image of Chevy and Camaro. "It makes sense for our business from a number of perspectives," he said. The first COPO Camaro, a Courtney Force-styled racecar that was revealed in November at the SEMA Show in Las Vegas, hammered for $300,000 at the Barrett-Jackson auction last month. The proceeds went to the United Way. Campbell said low COPO production keeps interest high. Enthusiasts can also build their own COPOs by buying a rolling chassis and a crate motor, though those are not viewed by collectors in the same manner as GM factory-built creations. The COPO Camaro's V8 is one of several competition engines designed, built, and validated at the GM Performance and Racing Center. The Corvette C7R's 5.5-liter V8 and the Cadillac ATSV.R's 3.6-liter twin-turbo V6 are two more. Chevy calibrates and conducts dynamometer testing on its 2.2-liter V6 for IndyCar and performs design work on its NASCAR V8 at the facility, which existed previously at another location in Michigan.
