BYD has confirmed the Denza N8, a large five-seat electric SUV, with a CLTC range of 1,003 km and a claim that it recharges from 10% to 70% in five minutes. Both numbers are records for a production battery-electric car. Both also come with an explanation.
What is actually in it
The N8 carries a 130.15 kWh Blade Battery 2.0 pack. It is 5,150 mm long on a 3,075 mm wheelbase — longer than a Model X — and comes as rear-drive with 320 kW or 370 kW, or as a tri-motor all-wheel-drive with 890 kW combined, split 270 kW front and 310 kW at each rear wheel. Pricing has not been announced. It is on sale in China.
The 1,003 km is bought with cells, not efficiency
Tesla's longest-range car on the same test cycle is the China-market Model Y, rated 821 km CLTC on a 78.4 kWh LG nickel pack. Divide range by capacity and the picture inverts:
| Pack | CLTC range | Energy per 100 km | |
|---|---|---|---|
| Denza N8 | 130.15 kWh | 1,003 km | 13.0 kWh |
| Model Y (China) | 78.4 kWh | 821 km | 9.5 kWh |
The Model Y is about a quarter more efficient. Denza's headline comes from carrying two-thirds more battery, which is a legitimate engineering choice — it is also heavier, more expensive to build and slower to charge in absolute terms per percent. CLTC is generous in both directions; a European WLTP figure would land well below 1,003 km, and the same haircut would apply to the Tesla.
Five minutes is a megawatt problem
Sixty percent of 130.15 kWh is 78 kWh. Delivering that in five minutes is an average of roughly 940 kW sustained — not a peak, an average. The 10-to-97% figure BYD also quotes, nine minutes, works out near 755 kW average. This is genuinely a step change, and it is the second time in a fortnight BYD has claimed it, after the Qin Max's own five-minute figure.
It also only exists where BYD has built the hardware for it. Megawatt-class public charging does not exist in Europe at any scale, and CCS2 installations that reach 400 kW are still rare enough to be a destination. A European N8, if it came, would charge at whatever the local network can give it.
Worth noting alongside this: Andreas Hensel of Fraunhofer ISE argued this week that megawatt charging is primarily a marketing instrument, and that the real constraint is the grid connection behind the site rather than the cable in front of it.
Where a Tesla owner stands
European Superchargers cap Teslas at 250 kW, as TeslAnt covered when a Zeekr was logged pulling 257 kW from one. A Model Y Long Range takes roughly 25 to 30 minutes for 10–80% on a V3 stall, or 18 to 24 on a V4. Against a five-minute claim, that is not a close comparison — on paper.
Does the N8 reach Europe?
Denza is no longer hypothetical here. BYD launched the brand in Europe at Paris in April 2026 with the Z9GT and D9, opened orders in the UK, France, Germany, Italy and Spain, and has said it wants around 30 European markets and 150 retail outlets. The Z9GT is already marketed on a nine-minute charging figure.
The N8 has not been announced for Europe. But the brand, the dealers and the battery are all in place, which is a different situation from a Chinese range record that stays in China.
