Notes and sources

  1. Fuel economy: EPA combined test-cycle figure for the configuration Silverado 2WD (23 city, 33 highway). EPA data dated 2026-09-09, the latest modifiedOn date EPA records in vehicles.csv.
  2. CO₂: EPA's tailpipe rating for the car driven as rated on the test cycle — 383 g/mi, or 238 g/km.
  3. Fuel cost: not estimated. This site has no diesel price source yet, so no cost is computed for a diesel car.
  4. Power: 275 hp is the rated figure, from EPA test-car data.
  5. Crash rating: NHTSA rated vehicles under this nameplate, but the ratings differ between the configurations it tested and none of them is this car's, so no rating is stated.
  6. Recall campaigns: NHTSA's count for this variant (SILVERADO 1500), as of 2026-09-10. Each is repaired free of charge by dealers.
  7. Complaints: NHTSA holds 93 for the 2021 Silverado, 5 of which describe a crash, fire, injury or death. The rate per 10,000 built is not computed: complaints no VIN places, or production no fuel code places, make the rate uncertain by more than 5%.
  8. Kerb weight: not published. No source states a curb weight for this car.
  9. EPA test weight: 5,250 lb (2,381 kg) is the equivalent test weight class EPA tested this configuration at, not the kerb weight.
  10. Warranty: 3 years or 36,000 miles, from Chevrolet's published 2021 warranty statement, compiled into carstandings.com's warranty table.
  11. Registrations: 793 Silverados of this model year on New York's roads, from the NY DMV registration file as of 2026-09-02.
  12. This car is measured on the diesel scale: miles per gallon, the tailpipe CO₂ rating and whole-car horsepower. MPGe and charge-weighted CO₂ are electric-scale quantities and do not apply to it.
  13. Price: no free, resellable source publishes a price for any 2021 car sold in the United States, so none is shown for any car in this market.
