Cars   EPA-estimated fuel economy for four-wheel drive models is 29 mpg highway

The 2020 Chevrolet Silverado 1500 with the available, all-new 3.0L Duramax turbo-diesel engine delivers an EPA-estimated 33 mpg highway and 23 city in rear-wheel-drive models. EPA-estimated fuel economy for four-wheel drive models is 29 mpg highway/23 city.

Silverado DuramaxWith an SAE-certified 277 horsepower and 460 lb-ft of torque, the Silverado 3.0L Duramax with four-wheel drive is also capable of towing up to 9,300 pounds and a max payload of 1,870 pounds, meeting the towing needs of about 90 percent of light-duty customers. This is the first diesel offered in Chevrolet’s light-duty trucks since 1997, and the brand’s first-ever inline-six for full-size, light duty trucks.

Silverado DuramaxHighly 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.

Silverado DuramaxIt 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.

Silverado DuramaxThe 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.
