This engine suits fleet operators, families, and those prioritizing MPG without sacrificing usable low-end torque for merging or light towing.
3.0L Duramax Turbo-Diesel Inline-Six: Torque King for Towing
The segment-exclusive 3.0-liter Duramax turbo-diesel I6 carries over with strong credentials for heavy towing and long-distance efficiency. Known for excellent low-RPM torque and drivability, it remains a top choice for serious haulers and those who tow frequently.

Replacing the previous 5.3L V8, the all-new 5.7-liter naturally aspirated V8 brings more displacement and modern engineering for improved power, torque, and refinement while honoring Chevy’s Small Block heritage. It’s engineered for a wide range of duties, from daily driving to moderate towing.
Estimated Specs: Around 400 hp and 420-430 lb-ft of torque (based on early reports and comparisons). Strong towing capability expected in the 12,000 lbs range.
This V8 appeals to traditional truck enthusiasts seeking classic V8 sound and feel with better efficiency and capability.
6.6L Sixth-Gen Small Block V8: Most Powerful Option
The flagship 6.6-liter V8 replaces the prior 6.2L and is touted as delivering the most powerful naturally aspirated V8 in the class. Built for maximum performance, it targets buyers needing top-tier horsepower and torque for heavy workloads, acceleration, and prestige trims like High Country.
