The BYD Seal was BYD’s answer to the Tesla Model 3: a sleek electric saloon with a big battery, lots of equipment and a longer warranty. Two years on, both cars have been updated. So which is the better buy in 2026? Here is how they compare on price, range, charging, space, running costs and what the experts say.

|---|---|---|
| Starting price | £45,730 (Design RWD) | £37,990 (Standard RWD) |

Price: the Tesla is cheaper
When the Seal launched it undercut the Model 3. That is no longer true. The Model 3 Standard starts at £37,990, nearly £8,000 less than the Seal Design, and the Premium Long Range RWD at £44,990 is still cheaper than the Seal while going considerably further. BYD dealers have discounted the Seal heavily, so ask for a deal, but on list price the Tesla wins.
Neither car gets the Electric Car Grant: the Seal because it is built in China, and the Model 3 because it costs more than the grant allows on most versions.
Range and charging: Tesla again
The Seal Design’s 354-mile range is strong, but the Model 3 Long Range RWD claims 466 miles, among the best of any car on sale. Tesla is also more efficient, which means lower charging bills for the same distance.
Charging speed matters on long trips. The Seal peaks at 150kW, which is slow for a car at this price, and takes around 37 minutes from 10 to 80%. The Model 3 Premium charges at up to 250kW and has access to Tesla’s Supercharger network, which is still the most reliable in the UK. See our charging times and costs for every Chinese EV for the full picture.
Interior and equipment: the Seal fights back
This is where the BYD earns its place. Reviewers consistently praise the Seal’s cabin: soft materials, solid switches, a Dynaudio sound system and a long list of standard kit. The Model 3 has improved since its 2024 update, but its minimalist cabin puts almost everything on the central screen, and it still does not offer Apple CarPlay or Android Auto. The cut-price Model 3 Standard feels noticeably more basic inside.
The Seal is not perfect here either. Its touchscreen is hard to use on the move, and several reviewers found its driver-assistance warnings overly intrusive.
Practicality
The 2026 Seal update grew its boot from 400 to 485 litres, with a 72-litre front boot. That is a big improvement, but the Model 3 still has more: 594 litres plus an 88-litre front boot. Both have saloon boot lids rather than a hatchback, so neither is ideal for bulky items.
Driving
Most UK reviewers find the Model 3 sharper and more polished to drive, with a better-controlled ride. The Seal is quick, especially the 523bhp Excellence, which does 0-62mph in 3.8 seconds, but it feels less composed on bumpy British roads.
Running costs
- Insurance: the Seal sits in groups 48 to 50, some of the highest of any family car. The Model 3 ranges from 32 to 48. See our insurance groups guide.
- Warranty: a clear win for BYD. Six years of car cover against Tesla’s four, and a battery warranty up to 155,000 miles. See our warranty comparison.
- Depreciation: early Seals lost around 40% in two years as BYD cut prices, a risk covered in our depreciation guide.
- Company car tax: identical, as both are zero-emission.
What the experts say
- Auto Express: Seal 3.5 out of 5; Model 3 4.5 out of 5.
- Top Gear: Seal 6 out of 10.
- Carwow: Seal 8 out of 10.
- Driver Power 2026 owner survey: the Model 3 was the top-rated car overall.
Verdict: which should you buy?
For most buyers, the Tesla Model 3 is the better car. It is cheaper, goes further, charges faster, has more luggage space and costs less to insure. The BYD Seal makes sense if you value a plusher, better-built cabin, more standard equipment and a much longer warranty, and if your dealer will give you a strong discount. If you choose the Seal, the Design RWD is the one to have.
