The 2023 Chevy Silverado HD is the heavy-duty pickup truck’s final model year before the introduction of a mid-cycle refresh for the 2024 model year. Now, GM Authority has learned when the start of regular production (SORP) for the 2023 Chevy Silverado HD is set to begin at the GM Oshawa plant in Canada.
According to GM Authority sources, the SORP for the 2023 Chevy Silverado HD is set to kick off at the GM Oshawa plant on September 12th, 2022. Meanwhile, the SORP for the Silverado HD at the GM Flint plant in Michigan is still on track to begin July 18th, 2022, as GM Authority covered previously.
The 2023 Chevy Silverado HD was previously slated to introduce a full model refresh for the heavy-duty nameplate, but as a result of delays stemming from the COVID-19 pandemic, the refresh was pushed back by one model year to 2024. With that in mind, the 2023 Chevy Silverado HD will introduce just a handful of small changes and updates as compared to more substantial changes slated for the 2024 model year.
The Chevy Silverado HD is currently performing well in terms of sales, with continuing high demand from customers. Although Silverado HD sales were down 7.5 percent during the 2021 calendar year, the drop in sales is the result of limited availability at the dealer level. Now, with production set to ramp up at the GM Flint plant later this month and at the GM Oshawa plant in September, short-term availability should be bolstered considerably.
Under the hood, the 2023 Chevy Silverado HD is offered with two engine options, including the naturally aspirated 6.6L V8 L8T gasoline engine, rated at 401 horsepower at 5,200 rpm and 464 pound-feet of torque at 4,000 rpm, as well as the 6.6L V8 L5P turbodiesel Duramax engine, rated at 445 horsepower at 2,800 rpm and 910 pound-feet of torque at 1,600 rpm. Under the skin is the more-capable version of the GM T1 platform.
