2021 Highlights - Fullsize Diesel Pickups
• The 2021 Ram 1500 HFE "High Fuel Efficiency" model powered by the 3.0L EcoDiesel receives a 1 mpg improvement over previous model years, matching the max EPA rating earned by General Motor's Silverado/Sierra 1500 models equipped with the 3.0L Duramax.
• The high output Cummins turbodiesel sees improved horsepower and torque numbers, bringing total peak output to 420 horsepower and 1,075 lb-ft. The high output variant of the 6.7L Cummins remains exclusive to Ram 3500 models.
• Ram Trucks steals several best-in-class titles for 2021, including best-in-class torque for its Ram 3500 models equipped with the high output Cummins turbodiesel, in addition to several towing and payload categories.
• The diesel option for Ford F-150 models is only available on 4 wheel drive platforms; a 2 wheel drive version is not available for the 2021 model year.
• Chevrolet/GMC and Ford heavy duty models largely remain carryovers from the 2020 model year.

[1] Class 2 refers specifically to a class 2B pickup truck with a GVWR between 8,501 and 10,000 lbs, as defined by the NHTSA. Often expressed as a 3/4 ton pickup. The Ford F-250 and Chevrolet Silverado/GMC Sierra 2500HD are available with optional payload packages that exceed the 10,000 GVWR limit; these offerings do not qualify to compete in this class despite arguably being 3/4 ton models.
[2] Class 3 refers specifically to a class 3 pickup truck with a GVWR between 10,001 and 14,000 lbs, as defined by the NHTSA. Often expressed as a 1 ton pickup. This class has been split into single rear wheel (SRW) and dual rear wheel (DRW) sub-classes due to the large difference in payload capacity and tow ratings between a SRW and DRW vehicle.
