What are the CO2 emissions of a NIO ET7?

Official EU monitoring data for 2025 registrations shows fleet-average CO2 from 0 g/km (WLTP) for the NIO ET7, varying by fuel type and configuration; the table on this page lists every year and fuel type.

How many NIO ET7 are registered in the EU?

The EEA monitoring database records 1,940 new NIO ET7 registrations in Europe between 2010 and 2025. These are new-car registrations reported by member states, not the number currently on the road.

NIO ET7: CO2 & EU registrations

1,940 new registrations on record, fleet-average CO2 from 0 g/km (WLTP, 2025). Official data reported by EU member states.

By year and fuel type

Fleet averages across all NIO ET7 registrations of that year and fuel. CO2 is WLTP where available (NEDC shown for older years). Consumption is l/100km for combustion, Wh/km for electric.

Year	Fuel	Registrations	CO2 NEDC	Consumption	Mass kg	Power kW
2025	Electric	139	-	212 Wh/km	2,454	452
2024	Electric	399	-	205 Wh/km	2,454	383
2023	Electric	698	-	199 Wh/km	2,448	303
2022	Electric	704	0 g/km	201 Wh/km	2,448	406
