Lower charging costs are the headline saving of an EV, but owners also want to know about everything else. Here is what changes, and what does not, compared with a petrol or diesel car.
Servicing
EVs have far fewer moving parts. There is no engine oil, spark plugs, fuel filters or exhaust system to maintain. Routine servicing typically covers brakes, suspension, cabin filters, coolant for the battery and electronics, software updates and a battery health check. Service intervals and costs vary by manufacturer.
Tyres
EVs are often heavier than comparable petrol cars and deliver strong torque instantly, which can wear tyres faster. Smooth driving, correct tyre pressure and regular rotation help. Some EVs use tyres designed for low rolling resistance and quietness.
Brakes
Regenerative braking slows the car using the motor, which recovers energy and reduces wear on brake pads. Brakes still need checks, as rarely used brakes can corrode.
Insurance
Premiums depend on the vehicle's value, the insurer and your profile. EVs can cost more to insure because of their higher purchase price and repair costs. Compare policies, and consider add-ons that cover the battery and charging equipment.
Battery
The battery is the most expensive component, but it is designed to last many years and is usually covered by a long manufacturer warranty. Good charging habits help it last.
| Cost | EV compared with petrol |
|---|---|
| Energy per km | Usually much lower |
| Routine servicing | Usually lower |
| Brake wear | Usually lower |
| Tyre wear | Can be higher |
| Insurance | Can be higher |
