Diesel power can be the ideal choice for light-duty pickup truck customers, providing a combination of copious low-end twist with decent fuel economy. Now, we’re taking a closer look at the specs for the Chevy Silverado Duramax diesel engine and how they compare to rival powerplants from Ford and Ram.
For those who may not know, Chevy Silverado Duramax models are equipped with the 3.0L I6 LM2 turbodiesel engine, which produces 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm. Found under the hood of both the pre-refresh 2021 Chevy Silverado 1500 and fully refreshed 2022 Chevy Silverado 1500, Silverado Duramax models return upwards of 31 mpg, with a maximum payload capacity of 1,930 pounds and a max towing capacity of 13,300 pounds (both with the 2022 model year).
To note, the Chevy Silverado 1500’s corporate cousin, the GMC Sierra 1500, also offers the 3.0L I6 LM2 turbodiesel Duramax engine, but for the sake of simplicity, we opted to keep the Sierra out of this comparison, given its close similarity to the Chevy Silverado diesel in terms of specs. The only real difference between the two is with regard to fuel economy, with GMC Sierra Duramax 2WD models returning 30 mpg on the highway, as compared to the Silverado diesel’s 31 mpg.
Up next, we have the Ford Power Stroke diesel from the 2021 Ford F-150, a turbocharged 3.0L V6 rated at 250 horsepower at 3,250 rpm and 440 pound-feet of torque at 1,750 rpm. Fuel returns range as high as 27 mpg for 4WD models, while max payload is set at 1,840 pounds and max towing is 12,100. We should also mention that the Ford Power Stroke diesel is no longer available as of the 2022 model year, while the engine was only available in conjunction with 4WD for the 2021 model year, as covered by our sister publication, Ford Authority. We should also mention that GM Authority spy photographers recently captured images of Ford benchmarking a diesel-powered Chevy Silverado 1500.
Finally, we have the Ram EcoDiesel from the 2022 Ram 1500, which is also a turbocharged 3.0L V6. Output is rated at 260 horsepower at 3,600 rpm and 480 pound-feet of torque at 1,600 rpm, returning upwards of 33 mpg and providing a max payload rating of 2,090 pounds and max towing capacity of 10,010 pounds.
Check out the table below to see the specs side by side. For the sake of comparison, we also included the hybrid gasoline engines from Ford and Toyota.
