General Motors’ flagships, the Chevrolet Silverado HD and GMC Sierra HD, are getting major updates for the 2024 model year, as we’ve covered. However, the Silverado 1500 and Sierra 1500 are also entitled to some changes.
First, the Duramax 3-liter turbodiesel six-cylinder, which has been revised and made more efficient for 2023, will be available for the formidable Silverado ZR2. It will also be included as standard in the similarly capable Sierra 1500 AT4X.
This engine, remember, is mated to a 10-speed automatic transmission and now develops 305 horsepower and 495 lb-ft of torque.
In turn, the 2.7-liter turbo four-cylinder engine will now carry the TurboMax name. Offered in several entry-level versions of the Silverado and Sierra, it produces 310 horsepower and 430 torque, enough to tow up to 9,500 pounds. However, as our tests have shown, its energy efficiency is not better than that of the V6.
New body colors and wheel options are added to the menu for 2024, continuous exhaust is available for the 6.2-liter V8 and more trims will offer retractable side steps.
The 2024 Chevrolet Silverado 1500 and GMC Sierra 1500 go on sale this summer. A slight increase in prices is expected.
As far as GM’s electrification goes, the 2024 Silverado EV is expected to reach this speed in limited numbers. Deliveries to us will begin sometime in the spring of 2024. For the GMC Sierra EV, Canadians will miss out on the 2024 model year and will have to wait until the 2025 model year.
