Highlights

What the data says

Non-electrified petrol cars get the DGT C sticker. We calculate fuel with 95 petrol at 1,783 €/l, the Spanish average on 15/10/2026, and with real consumption, which is 24% higher than the official figure according to European Commission data.

Of the 166 models still sold new, the one that costs least is the Toyota Aygo X (1.0 Petrol 72 CV): 196 € a month, 2.348 € a year. Number 20 on the list, the Skoda Kamiq, costs 223 € a month: 27 € more than the first. The average across all 166 is 311 € a month, 72 € more than the average for all cars on sale (239 €).

For the Toyota Aygo X, the biggest cost is fuel: 135 € a month, followed by insurance (26 €) and maintenance (23 €).

15 of the top 20 are city cars or superminis: in our calculations, a small car pays less for maintenance and tyres. If you're after a small or compact SUV, the one that costs least is the Seat Arona: 219 € a month, at number 15.

The best-seller on the list is the Dacia Sandero: 38.537 registrations in Spain in 2025, adding up all its versions. With the version shown here it costs 220 € a month and comes in at number 16.

How we calculate it

The same assumptions as each car's page

  • Only models still sold new are included: those registered in 2025 according to the European Environment Agency's register.
  • Each model is included with its best-selling version of this engine type that is still on sale.
  • 15,000 km a year for 5 years, bought new. Real consumption: the type-approval figure plus the real-world gap measured by the European Commission.
  • Fuel: the average of filling stations in Spain on 15/10/2026. Electricity: 0,15 €/kWh, charging at home (rapid chargers cost several times more).
  • Road tax at the legal minimum rates and ITV at the average fee across regions. Insurance, maintenance and tyres: our own estimates, the same across Spain.
