Chevy Silverado's diesel engine achieves 33-mpg highway rating

The truck can tow up to 9,300 pounds.

General Motors has announced EPA-estimated fuel efficiency figures for the 2020 Chevrolet Silverado equipped with the company's 3.0-liter Duramax turbodiesel engine.

In its two-wheel-drive configuration, the pickup achieves 33 mpg on the highway and 23 mpg in the city, while the four-wheel-drive variant steps down to 29 mpg highway and 23 mpg city.

The engine delivers 277 horsepower and 460 pound-feet of torque, enough to tow up to 9,300 pounds or carry an 1,870-pound payload.

The 3.0-liter Duramax is the first diesel engine offered in Chevy's light-duty trucks since 1997 and the brand's first-ever inline-six configuration for the segment.

The optional powertrain costs $2,495 for the LTZ and High Country trims, or $3,890 over the cost of the 2.7-liter turbo engine in the LT and RST packages.
