The 2020 Chevy Silverado Duramax Diesel Is the Most Fuel-Efficient Truck in Its Class

The 2020 Chevrolet Silverado 1500 has just earned serious bragging rights as the most fuel-efficient full-size truck on the market. This is achieved with the newly available 3.0-liter Duramax turbodiesel inline-six, which has an EPA-estimated fuel economy rating of 23 miles per gallon in the city and 33 mpg on the highway for rear-wheel-drive models. If you upgrade to 4-wheel drive, it’s 23 mpg city/29 mpg hwy, which is still very impressive.

This diesel engine is not only efficient, but it puts up some impressive capability numbers as well. It makes 277 horsepower and 460 lb-ft of torque and 4WD models can tow up to 9,300 pounds and carry up to 1,870 pounds in payload. According to Chevrolet, this meets the towing needs of about 90% of light-duty truck drivers.

This is a significant move for Chevy trucks as this is the first diesel available in the Silverado 1500 since 1997 and its first-ever turbodiesel inline-six. This new Duramax engine achieves its excellent fuel economy through technology and engineering that includes an aluminum block helping to save weight, an active thermal management system that quickly warms up propulsion components, a 10-speed automatic transmission, and start/stop technology that turns off the engine at stoplights and turns it back on when you take your foot off the brake (yes, you can turn this feature off if you want).

The Duramax will be available in the LT, RST, LTZ, and High Country trims of the Silverado 1500. It’s a $2,495 option for the LTZ and High Country models, which is the same cost as upgrading to the 6.2-liter V8. For the LT and RST trims, upgrading to the diesel will cost an extra $3,890 over the 2.7-liter turbocharged inline-four.

This new diesel option adds even more mechanical variety to the Silverado, which was already available with a turbocharged four-cylinder, a V6 and two different V8 engines. Deliveries of the first diesel-powered 2020 Silverado 1500 trucks will begin this fall. Find a Chevrolet Silverado for sale
