Figures this car does not carry

Fuel economy (MPGe)Not published for this carFuel economy (MPGe) is published for electric and hydrogen cars, whose economy is published as MPGe: energy converted at 33.7 kWh per gallon, not fuel burned; this car is not one of them, so the figure is not the same quantity for it
Tailpipe CO₂ (charge-weighted)Not published for this carthis car's CO₂ is published as the tailpipe rating for the car driven as rated on the test cycle (266 g/km), not as a composite weighted across electric and fuel-burning miles, so it is not the quantity this list orders. It is published as Tailpipe CO₂

5-Year Running Costs

FuelUS$10,753
InsuranceUS$8,540 (modelled)
MaintenanceUS$7,800 (class estimate)
Repairsnot estimated — The repair estimate is built from NHTSA's recall and owner-complaint counts, and this car's recall count is not known.
Depreciationnot estimated — we hold no purchase price for this car, and it is not assumed.
Totalnot estimated — a component above is unknown or modelled

Running costs only — the purchase price is not included. The five-year running cost is an ESTIMATE, not a measurement of this car: only its fuel half is computed from the car's own measured consumption and a dated pump price (see fuel_price_source and fuel_price_as_of in the market's own figures); insurance, maintenance and repairs are class models. It orders no list and is not one of this market's published figures. Fuel is this car's own combined consumption over 15,000 km a year at 1.738 CAD a litre of petrol (Statistics Canada. Table 18-10-0001-01 Monthly average retail prices for gasoline and fuel oil, by geography; Canada; regular unleaded gasoline at self service filling stations, 2026-08). Adapted from Statistics Canada, Table 18-10-0001-01 Monthly average retail prices for gasoline and fuel oil, by geography, August 2026. This does not constitute an endorsement by Statistics Canada of this product. Costs are in US dollars; the CAD pump price is converted at 1 CAD = 0.73 USD, the rate set on 2026-09-13. Insurance, maintenance and repairs are models, not figures for this car: insurance from its power, weight and crash rating, maintenance from its make's class, repairs from its complaint and recall counts. They are shown for scale and are not used to rank it. Confidence is low: several components are modelled from class averages.
