Frequently asked questions
Is the Audi S e-tron GT worth the extra £63,095 over the BYD Seal?
The Audi S e-tron GT costs £63,095 more than the BYD Seal. For that premium it adds 170 kW faster peak rapid charging, 270 kW more power and a 2.5s quicker 0-62mph time. The BYD Seal is not just cheaper - it also offers 1 more seat (5 versus 4). On EVcarsguide's combined category scores, the BYD Seal comes out ahead overall.
Which is cheaper to own over 5 years, the Audi S e-tron GT or the BYD Seal?
The BYD Seal is £63,095 cheaper to buy. Running costs are almost identical - about £184 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the BYD Seal comes out roughly £63,135 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Audi S e-tron GT and BYD Seal like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 311 miles for the Audi S e-tron GT and 244 miles for the BYD Seal - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi S e-tron GT goes roughly 66 miles further between charging stops. A rapid charge to 80% takes around 18 minutes in the Audi S e-tron GT and 37 in the BYD Seal, so the Audi S e-tron GT loses less time at each stop. That makes the Audi S e-tron GT the stronger long-distance car.
Which is easier to park and drive in town, the Audi S e-tron GT or the BYD Seal?
The BYD Seal is the easier car for tight UK car parks: it is 89 mm narrower than the Audi S e-tron GT. In a standard 2,400 mm bay that leaves about 525 mm of total clearance for the BYD Seal and about 436 mm of total clearance for the Audi S e-tron GT. The BYD Seal also turns in a 0.4 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Audi S e-tron GT or the BYD Seal?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi S e-tron GT and 90% for the BYD Seal. That gives the BYD Seal a modest edge in retained real-world range. The BYD Seal's LFP-type pack tolerates daily 100% charging, while the Audi S e-tron GT's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
