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.

New Chevy Small Block crate engine has 405 hp, endless possibilities

With decades of history, the Chevrolet Small Block V8 has definitely stood the test of time, and the company has kept finding ways to make it better. At this year's SEMA Show in November, Chevy Performance is unveiling the latest upgrade to that legacy with the new ZZ6 350-cubic-inch (5.7-liter) crate engine. Offering 405 horsepower and 405 pound-feet of torque, the mill should add a big dose of power to any project car. For the ZZ6, Chevy is working to improve the Small Block's high-rpm performance. To make that happen, the engine has Fast Burn aluminum cylinder heads and an updated valvetrain inspired by the LS family of powerplants. Large intake runners help with the airflow, and the valve springs use a tapered design that allows for less reciprocating mass. The mill also packs a forged steel crankshaft and high-silicon aluminum pistons inside of a cast iron block. Chevy is offering the engine in two versions depending on what the builder needs. The Base configuration comes with an intake, distributor, water pump, and a few other parts but lacks carburetor and accessories. Conversely, the Turn Key option has everything, including the carb, air cleaner, starter, alternator, and more. More details about their availability will be announced at SEMA. NEW ZZ6 CHEVY SMALL BLOCK ADVANCES CRATE ENGINE LEGACY Revised Fast Burn heads with LS-inspired valvetrain enhance high-rpm performance 2015-10-02 DETROIT – Developed with contemporary technologies, including a high-rpm valvetrain, Chevrolet Performance's new ZZ6 crate engine offers builders a modern twist on the classic Chevy Small Block 350. It uses updated Fast Burn cylinder heads with beehive-style valve springs inspired by the LS engine family – a feature that enhances high-rpm capability, enabling the new high-performance engine to achieve 405 horsepower and 405 lb-ft of torque. That's more power than any factory produced 350 engine ever installed in a Chevrolet production vehicle and it's one of the most powerful 350 Small Block-based crate engines in the nearly 27-year history of the "ZZ" lineup. "The new ZZ6 is the ultimate ZZ 350-based crate engine from Chevrolet Performance," said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports.

Chevy, GMC and Ram dealers are worried they'll run out of new pickups

One of the unexpected side effects of the ongoing coronavirus pandemic is a shortage of pickups at Chevrolet, GMC and Ram dealers. Supplies are running out, and the factories that build these trucks remain closed. Stores across the nation began increasing incentives in March, when the first stay-at-home orders were issued, in a bid to continue luring buyers into showrooms. They also launched online sales channels, or expanded their existing digital business. Sales nonetheless plummeted in April 2020, but in-demand vehicles, like the Ram 1500 and the Chevrolet Silverado, are still selling relatively well thanks in part to the aforementioned incentives. Pickups outsold sedans for the first time in April 2020, according to The Detroit News, by 17,000 units. The problem is that General Motors, Fiat Chrysler Automobiles (FCA), and Ford temporarily closed their factories in March. "The pipeline is very dry," said Mike Maroone, the CEO of a large dealership group named Maroone USA, in an interview with Automotive News. He told the publication his Chevrolet stores are sitting on a 30-day supply of the Silverado, which is one of America's best-selling vehicles. "That is a problem for us," he concluded. Coronavirus-related lockdowns and factory closures compound problems already faced by dealerships who represent General Motors-owned brands. They entered 2020 with a thinner inventory than a year earlier due to the 40-day United Auto Workers (UAW) strike that paralyzed the company late in 2019, and the 0%, 84-month offers announced in March have sapped supply. Ram wasn't affected by a strike, but it has relied heavily on generous incentives to move trucks off lots. Ford, on the other hand, limited incentives to 2019 models. Inventory levels differ greatly from region to region. The national average for the Silverado stood at an 82-day supply in March 2020, down from 120 in March 2019. Ram stores had a 114-day supply of the 1500 (compared to 134 a year earlier), while Ford bucked that trend with a 111-day supply versus 84 in 2019. Don't panic if you're in the market for a truck; we're not facing a complete drought. Automotive News added that America's light-duty pickup inventory could fall to 400,000 units by the end of May, and drop further to 260,000 units in June. For context, there were about 700,000 light-duty trucks in stock in May and June of 2019. That's unquestionably a sharp drop, but there will still be over a quarter of a million trucks to choose from.
