2024 Chevy Silverado ZR2 adds Duramax turbo-diesel option

Official info for the 2024 Chevrolet Silverado just dropped, and the biggest news is powertrain related.

GM’s smooth and stout Duramax 3.0-liter turbo-diesel inline-six is being added to the list of available engines for the off-road ZR2 model. Previously, the ZR2 was sold exclusively with the 6.2-liter V8. Now that the diesel is available, it presents a unique proposition in the off-road truck world that neither Ford nor Ram offer with their most extreme off-road trucks. Output for the diesel sits at 305 horsepower and 495 pound-feet of torque, which predictably lags in ponies versus the gas V8, but trounces it in torque.

Another powertrain update concerns the 2.7-liter turbocharged four-cylinder. Chevy is giving it a new name, so when you go to select it now, it’ll be referred to as the “TurboMax” option. It makes the same 310 horsepower and 430 pound-feet of torque as before and continues on as the standard engine in most trims. The last change is the addition of a new Active Exhaust for Silverados with the 6.2-liter V8. This is a valved exhaust that opens up in Sport mode for a more aggressive note.
