Notes and sources

  1. Fuel economy: Natural Resources Canada's combined rating for the Sierra WT, 11.2 L/100 km (21 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 — 263 g/km, or 423 g/mi.↩
  3. 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.↩
  4. Recall campaigns: NHTSA's count for this nameplate (Sierra), as of — a US register. Each is repaired free of charge by dealers.↩
  5. Not published for this car. The record's own reason is free to read with an account.↩
  6. This car is measured on the petrol scale: litres per 100 km, the tailpipe CO₂ rating and horsepower. MPGe and charge-weighted CO₂ are electric-scale quantities and do not apply to it.↩
  7. 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.↩
