Highly durable materials make up key components, including iron cylinder liners within the aluminum engine block, a forged steel crankshaft and connecting rods as well as blended silicon/aluminum pistons for greater heat resistance and reduced expansion. The engine was subjected to the same extreme simulated and real-world performance testing every Chevrolet truck engine undergoes to ensure the highest standards of durability and performance. The inline-six engine provides an inherently balanced configuration for low noise and vibration characteristics.
It features an aluminum block for weight reduction, an 84mm x 90mm bore and stroke, dual-overhead camshafts and four valves per cylinder. A new active thermal management system warms up propulsion components more quickly for more efficient operation. The exhaust brake, which is available in tow-haul mode, can provide additional driver confidence when towing, especially when going downhill. The driver-selectable stop/start technology enhances fuel economy by shutting off the engine at stoplights and certain other stop-and-go situations, helping save fuel.
The engine automatically restarts when the driver takes his or her foot off the brake. The 3.0L Duramax is exclusively paired with a Hydra-Matic 10L80 10-speed automatic transmission, featuring smaller gear steps and an overall larger ratio spread to enable peak efficiency. Intelligent controls adjust to the driver’s needs for smooth operation and aggressive response. The Duramax 3.0L turbo-diesel marks Chevrolet’s fourth diesel truck in the available lineup, joining the Colorado, Silverado HD and Silverado Medium Duty. ■
