How Noisy Are Electric Cars?

Electric cars are significantly quieter than petrol or diesel cars at low speeds, but they are not completely silent. At urban speeds you will notice the absence of engine noise, the hum of the tyres on the road surface, and the faint whine of the electric motor. At motorway speeds, wind and tyre noise become the dominant sounds, much as they do in a well-insulated combustion car. You can read more about EV ownership practicalities in our guides section.

Why are electric cars required to make noise at low speeds?

Since July 2019, all new electric and hybrid vehicles sold in the EU and UK must be fitted with an Acoustic Vehicle Alerting System, known as AVAS. This is a speaker system that generates a synthetic sound at speeds below around 20 km/h (roughly 12 mph) so that pedestrians, cyclists, and people with visual impairments are alerted to the car's presence. Above that speed, tyre noise is considered sufficient warning. The tone varies between manufacturers, and some have put considerable effort into designing pleasant sounds.

What noise does an electric motor make?

The motor itself produces a smooth, high-pitched whine that rises and falls with speed. Many drivers describe it as similar to a turbine or a large fan. It is much less intrusive than the mechanical clatter of a combustion engine, particularly at idle. Under hard acceleration the tone becomes more pronounced, but it remains fundamentally different from the aggressive roar of a petrol engine. Some drivers find the near-silence takes a little getting used to, particularly when pulling away at a junction.

Do tyres make EVs noisier than expected?

This catches many new EV owners off guard. Because the engine noise that used to mask road noise is gone, tyre hum and road surface texture become far more audible in the cabin. Some EVs also use tyres with reinforced sidewalls to handle the extra weight of the battery pack, and these can generate more road noise than standard tyres. Manufacturers increasingly address this with additional cabin sound insulation and by specifying tyres designed to minimise rolling noise.

How does cabin insulation compare between EVs and petrol cars?

Many EV manufacturers invest heavily in acoustic insulation precisely because road and wind noise are no longer masked by the engine. Premium and mid-range EVs often use double-glazed windows, additional door seals, and sound-deadening materials in the floor and firewall. The result is that many drivers find motorway journeys in a modern EV noticeably more relaxing than in an equivalent petrol car, even if the overall sound levels are broadly similar at high speed.

Is the reduced noise a benefit in residential areas?

Yes, and this is one of the quality-of-life advantages of EV ownership that rarely features in the headline comparisons. Arriving home late at night, leaving early in the morning, or manoeuvring in a quiet car park generates far less disturbance than a cold-start petrol engine. Urban residents who have switched to EVs frequently mention this as one of the unexpectedly welcome aspects of ownership.

Frequently asked questions

What is AVAS and do all electric cars have it?

AVAS stands for Acoustic Vehicle Alerting System. Since July 2019, all new electric and plug-in hybrid vehicles sold in the UK and EU have been required to have one fitted. It produces a synthetic pedestrian warning sound at low speeds. Older EVs produced before this date may not have AVAS, though many were retrofitted voluntarily.

Can you turn off the pedestrian warning sound in an EV?

No. AVAS is a legal safety requirement and cannot be disabled by the driver. The sound operates automatically at speeds below the threshold set by the manufacturer, typically around 12 mph. Some manufacturers allow the driver to choose between different AVAS sound profiles, but switching it off entirely is not permitted.

Are electric cars quieter inside the cabin or just outside?

Both, but the effect is most noticeable inside. With no combustion engine vibrating through the drivetrain and into the cabin, interior noise levels at urban speeds are considerably lower than in a petrol car. At motorway speeds the gap narrows, as wind and tyre noise dominate both types of vehicle.

Do EVs disturb neighbours when charging overnight?

Home charging is essentially silent. The vehicle itself makes no meaningful noise while connected to a home charger, and the wallbox or cable produces only a faint electrical hum at most. This is a noticeable contrast to running a petrol engine to warm up, and is one reason many EV owners prefer overnight charging on a home unit.

Are heavier EVs noisier due to tyre noise?

The extra weight of a battery pack does increase the load on tyres, which can contribute to more road noise on coarse surfaces. However, this is largely managed through tyre selection and cabin insulation. A well-engineered EV with appropriate tyres and good sound deadening can be very quiet despite the additional mass compared to an equivalent petrol car.

Will I find the near-silence of an EV unsettling at first?

Many new EV owners describe a brief adjustment period where the quietness feels unfamiliar, particularly when reversing or manoeuvring slowly. Most drivers adapt quickly and then find returning to a loud petrol car noticeably jarring. The AVAS tone provides enough auditory feedback at low speeds that genuine disorientation is rare.

If the near-silence of EV driving has convinced you to make the switch, the next step is sorting out how you will charge.
