2023 GMC Sierra 2500 PERFORMANCE 
6.6L V8 GAS ENGINE
- 401 hp
- 464 lb.-ft. of torque
- 6-Speed Automatic Transmission
- 10.8:1 compression ratio
- Valvetrain: Overhead-valve (two valves per cylinder) with variable valve timing
OPTIMIZED ENGINE PERFORMANCE
Engineers worked to make this already powerful engine perform more efficiently by optimizing its cooling capacity by way of a large radiator and fan and improving the air induction system.
- The dual-path intake system draws dense, cool air to enhance performance
- To help maintain optimal operating temperatures, the available Duramax Diesel features an integrated engine after-run cooling function
- The integrated engine after-run cooling function can continue to idle the engine after extended and exhaustive periods of use and allows for proper cool-down of vital underhood components
STAY COOL UNDER PRESSURE
- Dense, cool air from the Dual Path Air Induction System is drawn through the hood scoop and the large grille to help optimize horsepower trailering performance
- A 28" variable-speed cooling fan helps maintain optimal operating temperatures of the available 6.6L Duramax Turbo-Diesel V8 Engine
- The factory-installed Diesel After-Run feature helps cool down the engine following heavy usage
