Notes and sources

  1. Fuel economy: Natural Resources Canada's combined rating for the Silverado, 8.8 L/100 km (26.7 mpg, US gallons). The NRCan file is dated 2026-09-15, the Last-Modified sent by the server with nrcan_2015-2024.csv.↩
  2. CO₂: NRCan's tailpipe rating for the car driven as rated on the test cycle — 238 g/km, or 383 g/mi.↩
  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 — a US register. 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: 2,381 kg (5,250 lb) is the equivalent test weight class EPA tested this configuration at, not the kerb weight.↩
  10. Warranty: 3 years or 60,000 km, 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: litres per 100 km, 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 Canada, so none is shown for any car in this market.↩
