New for the 2023 model year, the refined second-generation 3.0L inline-six turbo-diesel Duramax is expected to deliver additional power and torque.

This engine is primed to deliver a sizable increase in power and torque for diesel customers. The max power is 305 hp, a 10% increase (277 hp in 22MY), and max torque 495 lb-ft, a 7.6% increase (460 lb-ft in MY22), thanks to several key component upgrades for optimum performance, including:

  • New steel pistons with a revised combustion bowl
  • Retuned turbo compressor
  • New fuel injectors
  • Improved temperature control features
“These improvements to the popular 3.0L Diesel Duramax build on the already advanced design of the first-generation engine,” said John Barta, assistant chief engineer of diesels engines. “We often hear customers express their satisfaction with the outstanding fuel economy and smooth quiet power of the current diesel engine, so we can’t wait for them to experience this advanced engine made possible by the continued design evolution and advances in engine technologies.”

This refined diesel engine will be available on Custom Trail Boss, LT, RST, LT Trail Boss, LTZ and High Country, and will continue to be exclusively paired with a 10-speed automatic transmission for retail customers.

The Duramax engine will continue to be assembled at GM’s Flint Engine Operations in Michigan3. and will be available on select trims of the 2023 Silverado 1500 by the end of this year.
 
I love my Duramax 3.0 I almost have 10k miles on the truck. Maybe I'll add a Tahoe with the new engine to the fleet
 
Maybe next year Chevy will offer that new Duramax in the Z71 Tahoe.
 
I'm glad to see Chevy keep improving that engine. I was worried they would drop it from the line up.

Just hit 40k
First Transmission service did the PPE Transmission pan upgrade to keep the temps down. Took over 11qts of fluid for the service with the new pan!
Still loving this Truck
