BYD Seal
Tesla Model Y
The BYD Seal costs £3,740 more than the Tesla Model Y. For that premium it adds 40 miles more WLTP range and a 1.0s quicker 0-62mph time. The Tesla Model Y is not just cheaper - it also offers 25 kW faster peak rapid charging, 454 litres more boot space and lower energy use, 138 versus 166 Wh/km. On EVcarsguide's combined category scores, the Tesla Model Y comes out ahead overall.
The Tesla Model Y is £3,740 cheaper to buy. The Tesla Model Y is cheaper to charge, roughly £152 a year versus £184 for the BYD Seal, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Tesla Model Y comes out roughly £3,900 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 244 miles for the BYD Seal and 251 miles for the Tesla Model Y - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV.
The BYD Seal is the easier car for tight UK car parks: it is 106 mm narrower than the Tesla Model Y. In a standard 2,400 mm bay that leaves about 525 mm of total clearance for the BYD Seal and about 419 mm of total clearance for the Tesla Model Y. The BYD Seal also turns in a 0.9 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD Seal and 90% for the Tesla Model Y. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day. Both batteries carry a 8-year manufacturer warranty.
