How the 2021 GMC Yukon XL 4WD running costs are calculated
Every figure on this page is calculated from official certified data — nothing is estimated, and no figure is carried over from a similar car:
- Consumption and CO₂ are the certified values recorded in Natural Resources Canada (NRCan), taken across the 1 configuration held for this model-year.
- Annual cost is consumption × distance × the market's current average price for petrol, at 15,000 km a year.
- The roadworthiness test and road tax use the Canada national figures shown above. This market has no annual road tax for private cars, so none is charged here.
- Deliberately excluded: insurance, servicing, tyres, repairs and depreciation. They depend on the driver, the policy and the individual car, so putting a number on them would mean inventing one.
