The 2020 Chevrolet Silverado 1500 with the optional 3-liter 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.
With an SAE-certified 277 horsepower and 460 lb-ft of torque, the Silverado 3-liter Duramax with four-wheel drive can tow up to 9,300 pounds and a max payload of 1,870 pounds. The first deliveries of the Duramax turbo-diesel are expected to begin in the fall.
This is the first diesel offered in Chevrolet’s light-duty trucks since 1997, and the brand’s first-ever inline-six configuration for full-size, light duty trucks.
Chevy claims 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 heat resistance and reduced expansion.
The inline-six engine provides an inherently balanced configuration for low noise and vibration. It has as stated 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 and get past the cold start emissions requirements for inherently dirty diesels.
- An exhaust brake, which is available in tow-haul mode, works wen 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 3L turbo-diesel is Chevrolet’s fourth diesel truck in the lineup, joining the Colorado, Silverado HD and Silverado Medium Duty. The company has diesel truck experience from the Silverado HD with the Duramax 6.6L Turbo-Diesel V8 and Colorado with the Duramax 2.8L Turbo-Diesel.
The new diesel option completes the all-new Chevrolet Silverado 1500 propulsion portfolio, which provides maximum customer choice through eight trims paired with six engine/transmission combinations. The 3.0L Duramax turbo-diesel is available on the LT, RST, LTZ and High Country trims. For the LTZ and High Country, the 3.0L Diesel is a $2,495 option, identical to that of the 6.2L V-8. For the LT and RST, it is a $3,890 increase over a 2.7L Turbo engine.
The 2020 Silverado 1500 propulsion lineup:
- The most advanced V-8s in the brand’s history and updated versions of Chevrolet’s older 5.3L and 6.2L engines equipped with industry-first Dynamic Fuel Management featuring 17 different modes of cylinder deactivation. The optional 6.2L RST achieves class-leading light duty towing capability of 13,400 pounds.
- An all-new, advanced 2.7L Turbo engine that replaces the 4.3L V-6 as the standard engine on the high-volume Silverado LT and new Silverado RST.
- Older 4.3L V-6 and 5.3L V-8 engines deliver full-size truck capability and performance for the most affordable trucks in the Silverado lineup.
