Coverage: Fewer plug-in hybrids are ranked for 2024 than for 2023 or 2025. EPA's 2024 fuel-economy file, the source of every US car in these standings, lists no plug-in version of several cars it lists for both of those years, among them the Ford Escape, Lincoln Corsair, Kia Niro, BMW X5, Volvo S90 and Porsche Cayenne. Those plug-in hybrids are missing from the 2024 standings, not ranked low.

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 (248 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

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. Confidence is low: several components are modelled from class averages.
