Official fuel economy numbers are in for the new 2020 Chevrolet Silverado 1500 diesel. Chevrolet says the all-new 3.0L Duramax turbo-diesel engine delivers an EPA-estimated 33-mpg highway/23 city in rear-wheel-drive models. That number drops to 29-mpg highway for four-wheel drive models.
Chevy says with 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. The automaker says that will meet the towing needs of about 90 percent of light-duty customers.
“We designed the all-new Silverado and the all-new 3.0L Duramax turbo-diesel to deliver both performance and efficiency,” said Tim Herrick, Silverado executive chief engineer. “The engine utilizes state-of-the-art technologies to optimize every drop of fuel, and takes advantage of architectural changes to make Silverado larger, lighter and more aerodynamic than before. The resulting combination offers all of the performance, refinement and capability customers want in a full-size truck, with highway fuel efficiency you would expect from a family sedan.”
Silverado 1500 Engineering and Testing
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.
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.
Chevrolet says 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, 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.
Chevrolet Diesel Lineup
The Duramax 3.0L turbo-diesel marks Chevrolet’s fourth diesel truck in the current lineup, joining the Colorado, Silverado HD and Silverado Medium Duty. The company says it draws on deep diesel truck experience from the Silverado HD with the Duramax 6.6L Turbo-Diesel V8 and Colorado with the Duramax 2.8L Turbo-Diesel.
Silverado 1500 Diesel Availability
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.
