The BYD Seal is a large electric saloon with a roomy cabin, a long official range from its 83kWh battery and plenty of standard equipment. As a used buy it is worth considering against a Tesla Model 3 or Polestar 2, provided you check the battery health, software updates and remaining warranty.

BYD is a large Chinese maker of electric cars and batteries. The Seal arrived in the UK in 2023 as a rival to the Tesla Model 3, and the first cars are now appearing on the used market.

What is the BYD Seal?

The Seal is a four-door, five-seat electric saloon. It is a little longer than a Model 3, with a low, smooth shape and a large boot plus a small storage area under the bonnet.

Two main versions have been sold in the UK:

Rear-wheel drive. One motor, the longer range of the two and the more relaxed character.
Four-wheel drive. Two motors and much quicker acceleration, at the cost of some range.

BYD has updated the Seal since launch, so check exactly which version and model year you are looking at.

What is it like to drive and live with?

Owners and road testers tend to praise the ride comfort, the quiet cabin and the amount of standard kit. The interior uses a large central touchscreen that can rotate between landscape and portrait.

The main criticisms are that some controls are buried in the screen, and that the driver assistance warnings can be over-eager. Most of these can be adjusted in the settings.

What range and charging should I expect?

The Seal uses a battery of around 83kWh with BYD's own lithium iron phosphate Blade cells. Official range figures are generous, but like any EV the real-world range will be lower in winter and at motorway speeds.

A heat pump helps efficiency in cold weather. For a full explanation of why range varies, read our guide to WLTP and real-world range.

What should I check on a used BYD Seal?

Battery health. Ask for a battery state-of-health report. Our guide to checking used EV battery health explains how.
Warranty. BYD sets separate warranties for the car and the battery. Check what remains and whether it transfers to you.
Software. Make sure the car has had its latest updates, which can improve the screen, driver aids and charging.
Service history. EVs still need regular checks of brakes, tyres, suspension and coolant.
Tyres. Heavy, powerful EVs can wear tyres quickly, especially four-wheel-drive versions.
Charging cables. Check the correct cables are included.

How does it compare with rivals?

The Tesla Model 3 has the most established charging network and strong resale values. The Polestar 2 feels more traditional inside. The Seal often offers more equipment for the money. Our Model 3 vs Polestar 2 guide covers those two in more detail.

Common questions

Is the BYD Seal reliable?

It is still a young model in the UK, so long-term data is limited. A full service history and a clean battery report matter more than the badge.

Does the BYD Seal hold its value?

Newer brands often depreciate faster than established ones, which can make a used Seal good value to buy. Factor that in if you plan to sell within a few years.

Do electric cars pay road tax?

Yes. Since April 2025, electric cars pay vehicle tax. See our guide to EV road tax.
