DURAMAX 6.6L V8 TURBO DIESEL

The available Duramax Diesel in the Sierra 2500 Denali HD delivers 397 hp and 765 lb.-ft. of torque, making it the most powerful Sierra HD ever. The Duramax Diesel engine has a strong reputation and a proven track record with over 1 million sold since 2000.4


ALLISON 1000 SERIES TRANSMISSION

The enhanced Allison 1000 is designed to handle the higher torque capability of the available Duramax 6.6L Turbo Diesel engine, while also helping improve fuel-efficiency and provide seamless assistance with the exhaust brake system.


DIRECT INJECTION TECHNOLOGY

For fast starts in cold weather, quiet operation and maximum efficiency, the direct injection system helps Sierra HD, with the available Duramax 6.6L V8 Turbo Diesel engine, start in as little as 3 seconds at -40ºC and operate at nearly 206,843 kPa (30,000 psi) – turning heavy diesel fuel into a fine mist, helping deliver low emissions and more power.


SUSPENSION

Sierra 2500 Denali HD delivers a smooth ride with a fully independent torsion bar front suspension and 76.2 mm (3”) wide multi-stage rear leaf springs, which engage progressively as the load in the bed or on the hitch increases.

VARIABLE VALVE TIMING

From strong, steady power to bold acceleration on the highway, the Vortec 6.0L V8 with Variable Valve Timing (VVT) is up to almost any task by:


  • Delivering power when needed and efficiency when less power is called for
  • Monitoring, opening and closing valves for near-peak levels of torque across a wide range of engine speeds

BRAKING SYSTEMS

To let you engage an extra measure of braking confidence on long grades or in Tow/Haul mode, Sierra 2500 Denali HD uses various technologies to ensure you stay at the desired speeds:
