Choses à considérer

Commodité de charge

La recharge à domicile pendant la nuit coûte moins cher que la recharge rapide publique et est pratique pour la plupart des chauffeurs. Les trajets plus longs nécessitent une planification autour des arrêts de recharge, bien que le réseau Tesla Supercharger couvre la plupart des itinéraires.

Incidences environnementales

Les véhicules électriques ne produisent aucune émission d'échappement. Le CO₂ à vie dépend de la combinaison de votre réseau électrique. Dans les pays à forte énergie renouvelable, les véhicules électriques sont nettement plus propres tout au long de leur durée de vie.

Taxe de circulation et incitations

De nombreuses régions offrent des incitations à l'achat de véhicules électriques, une réduction de la taxe de circulation et des frais de congestion moins élevés. Consultez le site Web de votre gouvernement local pour les programmes actuels.

• Longévité de la pile

Les batteries Tesla sont conçues pour durer entre 300 000 et 500 000 milles. Les données du monde réel montrent une perte de capacité inférieure à 10 % après 100 000 miles avec de bonnes habitudes de charge. La batterie est couverte par une garantie de 8 ans.

Fuel: where the gap between a Tesla and a petrol car is widest

On a typical UK home tariff a Model 3 or Model Y costs around 7p a mile in electricity. A petrol car returning 40 mpg at current pump prices is closer to 16p a mile. Over an average UK year of about 8,000 miles that's roughly £700 saved before you touch any other line item.

The caveat is where you charge. Lean mainly on public rapid chargers at 50–90p/kWh and the per-mile figure climbs towards petrol territory — which is why the calculator above lets you set your own electricity price rather than assuming everyone charges at home overnight.

Servicing, tyres and tax: the costs that aren't fuel

There's no oil to change, no spark plugs, no timing belt and no exhaust system, and regenerative braking means brake pads often last far longer than on a petrol car. That removes most of a routine servicing bill. Working the other way: tyres, which wear faster on a heavier car with instant torque, and insurance, which can run higher on a Tesla because of parts costs and the need to recalibrate cameras and sensors after even minor repairs.

Road tax is no longer a differentiator in the UK — electric cars lost their VED exemption in April 2025, so both sides of the comparison now pay it. EVs still avoid fuel duty entirely, which is where the bulk of the running-cost advantage has always come from.

Break-even: how long until the switch pays for itself

If the Tesla costs more to buy than the petrol car you're comparing it against, the running-cost saving has to close that gap before you're genuinely ahead. The calculator includes both purchase prices in the ten-year total, so the break-even point it shows is the year your cumulative spend on the Tesla drops below the petrol car's.

Annual mileage is the lever that moves it most — at 15,000 miles a year the saving accumulates roughly twice as fast as at 8,000. What the model deliberately leaves out is resale value; see the value estimator for what a used Tesla is worth today, since selling partway through shifts the picture in either direction.

Tesla vs petrol FAQs

Is an EV really cheaper to run than a petrol car?

For most owners who do the bulk of their charging at home, yes, and by a wide margin. On a typical UK home tariff a Model 3 or Model Y costs roughly 7p per mile in electricity, against roughly 16p per mile for petrol at current pump prices — call it a little over £700 a year cheaper on an average 8,000-mile UK driving year. That gap narrows, and can even reverse on paper, if you rely mainly on public rapid chargers rather than home or off-peak charging.

Does Tesla maintenance really cost less than a petrol car?

Generally yes. There's no oil, spark plugs or timing belt to replace, and regenerative braking means brake pads typically last far longer. Illustrative annual servicing costs used in this calculator put EV maintenance at roughly half a comparable petrol car's — though tyres often wear a little faster than on an equivalent ICE car, thanks to the instant torque and extra weight of the battery pack.

Why is my insurance quote higher for a Tesla than my old petrol car?

It happens more often than owners expect. Higher parts costs, specialist repair networks, and the cost of recalibrating cameras and sensors after even minor bodywork can push EV premiums above a comparable petrol car's, even though the Tesla is cheaper to fuel and service. It's one of the few line items where petrol cars sometimes come out ahead — worth shopping around rather than assuming an EV will automatically be cheaper to insure.

Does this calculator include the cost of buying the car?

Yes — the purchase price (after any grant or incentive) is included alongside the running costs, so the 10-year comparison and break-even point both account for what each car cost to buy. What it doesn't model is resale value: how much each car is actually worth if you sell it partway through, which can swing the total picture in either direction.
