2021 GMC Sierra 2500HD vs. Its Competition

2021 GMC Sierra 2500HD
Aaron Cole Aaron Cole Managing Editor

The GMC Sierra HD is related to the Chevrolet Silverado HD and steers more toward comfort and luxury rather than Chevy’s work-first trucks.

There aren’t many differentiators between the two, other than the GMC Denali version.

Crosstown rivals from Ford and Ram boast similar capabilities from their trucks and have a little more polish inside.

(Particularly the Ram heavy-duty pickups.) The Toyota Tundra and Nissan Titan XD aren’t in the same league as the domestic heavy-duty trucks but offer four doors and an open bed with a more reasonable price tag if you’re considering a truck as a family vehicle.

Quick Specs
The 2021 GMC Sierra Heavy Duty pickup lineup is impressive in its capability and performance.
Big, bold, and massively capable with gas and diesel engines, the 2021 Chevrolet Silverado 2500HD gets the job done.
The ginormous 2021 Ram heavy-duty lineup reports for work, home, weekend, and hauling detail all at the same time.
The 2020 Ford Super Duty has the towing technology and the goods to pull up to 37,000 pounds.
The 2020 Nissan Titan full-size pickup still aims for the margins among pickup buyers, and its value falls down in top trims.
The 2020 Toyota Tundra trades on its durable reputation rather than its appealing design.
