Chevy Silverado’s Duramax Diesel Engine Just Got More Power

With a rebellious cry, she cried more, more, more. Luckily for her, the Chevrolet Silverado 1500 was listening, because it’s about to get more power. Specifically, the Duramax diesel engine gets a boost for the 2023 Chevy Silverado 1500.

For the 2023 Chevy Silverado 1500, the Duramax 3.0-liter inline-six diesel engine develops 305 hp and 495 lb-ft of torque. This is a 10% power increase and a 7.6% torque increase.

Currently, the Duramax engine provides 277 horsepower and 460 lb-ft of torque. Additional power comes from engine component upgrades, such as new steel pistons with a revised combustion bowl, retuned turbocharger, new fuel injectors and improved temperature control features.

John Barta, assistant chief diesel engineer, said the improvements to the popular Duramax diesel build on the already advanced design of the first-generation engine.

He explained that Chevrolet often hears customers expressing their satisfaction with the outstanding fuel economy and smooth, quiet power of the current diesel engine.

They can’t wait to experience this advanced engine, made possible by continuous design evolution and advancements in engine technology.

The upgraded Duramax diesel engine for the 2023 Chevy Silverado will be available with Custom, Trail Boss, LT, RST, LT Trail Boss, LTZ and High Country trim levels. It is mated to the same 10-speed automatic transmission.

It’s basically available in all conditions, except for the new Silverado 1500 ZR2 Bison version, which is designed for off-roading. It’s a bit odd to keep this option out of an off-roader that could benefit from some extra torque.

The Chevy Silverado 1500 ZR2 Bison is only available with the 6.2-liter V8 engine that delivers 420 hp and 460 lb-ft of torque. It is also paired with the 10-speed automatic transmission with electronically locking front and rear differentials.

It features five underbody skid plates, rocker guards, stamped steel bumpers with integrated running boards and front tow hooks. The new bumpers are expected to improve the Silverado’s approach angles, but official numbers haven’t been released.

Additionally, the ZR2 Bison rolls on 18-inch wheels wrapped in 33-inch Goodyear Wrangler Territory MT tires. It has a ground clearance of 11.2 inches.

How much does the 2023 Silverado cost?

Pricing for the 2023 Chevy Silverado 1500 starts at $35,600. This is the MSRP, so the price does not include destination charges or dealer markups. Additionally, the Silverado ZR2 Bison bumps the price up to $78,490. The ZR2 starts at $71,545.

We will let you know once the official price of the upgraded Duramax diesel engine is released. So far, the upgraded Duramax engine and new ZR2 Bison are the only updates for 2023. But new options may emerge later in the year.

The Silverado just got an all-new interior design with updated technology for 2022, so it still feels fresh. We can’t wait to see how the ZR2 Bison and its new diesel engine compare to the rest of the lineup.
