About the 2020 GMC Sierra 2500HD

The 2020 GMC Sierra 2500HD is a truck that earns a Carivo score of 7.0/10 — rated Good. Its strongest dimension is Safety at 8.9/10, while Value at 7.2/10 is where it trails the competition most noticeably. It's a capable but unexceptional truck — stronger alternatives exist if you're willing to shop the segment carefully.

Reliability and safety are the two dimensions that matter most for long-term ownership costs. The reliability picture is solid rather than spectacular: 7.8/10, which puts it comfortably above the class median. On safety, it scores 8.9/10 in our assessment. Always confirm the official crash-test results for your exact trim at nhtsa.gov/ratings.

Few rivals match it for performance: 8.5/10. Expect handling and power delivery that make this one of the more entertaining trucks to actually drive. On technology it rates 8.4/10: a modern, well-integrated suite that compares favorably with anything at this price point.

Priced from $39,952–$51,704, 11 MPG, seating 5, the GMC Sierra 2500HD sits in the mid-market bracket of the truck segment. At 7.2/10 for value, it delivers fair pricing for what's on offer, though the best alternatives in this price range score slightly higher. At 6 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.

Verdict: The 2020 GMC Sierra 2500HD sits in the middle of the field. Worth a look if it fits a specific need; otherwise use our compare tool against the segment leaders first.
