Where the two differ is the whole answer. HEV and ICE rarely differ on every line; the decision lives in the two or three bars where they do. Ordinal comparison consistent with the total-cost-of-ownership literature cited on this page.

Powertrain comparisons in the total-cost literature reach different winners in different markets and at different mileages, and that is the finding rather than a failure of the studies: the answer genuinely depends on the inputs [1]. The lines below are where these two part company.

Where HEV and ICE differ
LineConventional hybridPetrol
Energy / fuelBest in stop-start urban driving, where regeneration does the most work; the advantage narrows to little on sustained motorway running. One fuel, one price.One line, one price, rising in step with distance. No cheap-tariff option exists.
MaintenanceReliable and cheap for the established systems; regeneration spares the brakes.Middle of the pack, rising with age and mileage in the familiar way.

On depreciation, insurance, tax & fees, financing cost the two behave much alike, and those lines will not decide it.

What decides it

For HEV: The low-friction choice for a driver without home charging or with a lot of urban driving. Rarely the cheapest option outright, seldom the most expensive.

For ICE: Still competitive at low mileage, where energy barely matters and the lower purchase price dominates. Loses ground steadily as distance rises and as tax regimes tighten.

The comparison shifts with annual distance — see Conventional hybrid at each mileage and Petrol at each mileage — and with the tax architecture of your market, described on the country pages.

Is HEV or ICE cheaper to own?
It depends on urban share of driving and annual distance. The low-friction choice for a driver without home charging or with a lot of urban driving. Rarely the cheapest option outright, seldom the most expensive. Still competitive at low mileage, where energy barely matters and the lower purchase price dominates. Loses ground steadily as distance rises and as tax regimes tighten.
Which holds value better, HEV or ICE?
HEV: Strong for the established makers — Toyota built its reliability reputation on this powertrain — and predictable, because there is no battery-generation cycle or charging-infrastructure story to reprice it. ICE: Well understood and stable — but watch the policy direction: as low-emission zones and CO₂-based taxes spread, higher-emission used cars face a slowly narrowing market in several European cities.
