The upcoming refreshed Chevy Silverado HD will launch for the 2024 model year, rather than the 2023 model year, GM Authority has learned.
It was previously unclear whether the refreshed Chevy Silverado HD would launch for the 2024 model year or the 2023 model year. However, new information has come to light that that indicates the refreshed heavy-duty pickup will in fact launch for the 2024 model year.
The refreshed 2024 Chevy Silverado HD follows a full model refresh for the light-duty Chevy Silverado 1500 introduced for the 2022 model year, the latter of which hit the scene following the release of the “stop-gap” 2022 Chevy Silverado 1500 Limited model.
Meanwhile, the fully refreshed 2024 Chevy Silverado HD will introduce a new design for the front and rear end, as well as a totally overhauled interior and a powertrain upgrade to boot. GM Authority previously caught a few prototypes of the refreshed pickup out for testing, giving us an early look at the revised exterior, as hidden by camo covers.
With regard to the powertrain update, the refreshed 2024 Chevy Silverado HD is rumored to introduce an update for the Duramax diesel engine that’s expected to boost output to nearly 1,100 pound-feet of torque and over 500 horsepower. For reference, the 6.6L V8 L5P turbodiesel Duramax in the current pickup is rated at 910 pound-feet of torque and 445 horsepower.
Also of note for the refreshed 2024 Chevy Silverado HD is the introduction of the new Silverado HD ZR2, a new trim level that will be available for single-rear wheel vehicles. As GM Authority was the first to report, the 2024 Chevy Silverado HD ZR2 will likely be equipped with new specialty dampers, aggressive 35-inch Goodyear Wrangler Territory MT tires, and locking differentials for the front and rear, giving the pickup an extra dose of off-road worthiness.
As for the 2023 Chevy Silverado HD, production will kick off in July, as GM Authority covered previously.
