Nio ET7: which version to buy
Between the two Nio ET7 versions on record, AT 70 kWh and AT 100 kWh, power is identical and the measured gaps are small: 0.1 s in 0–100 km/h, one extra set of published figures on the larger pack, and a 9-month later start date. There is one generation and one body, so the buy decision is not “which generation” — it is which pack name matches the numbers you need published.

Nio ET7 versions compared (1 generation)
The Nio ET7 has 1 generation, body Sedan, on sale from 2022-03-01 with no stop date in the data. That generation lists 2 versions.
| Version | Start | Power | Torque | Fuel | Cylinders | Layout | Boost | Displacement | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|---|
| AT 70 kWh | 2022-03-01 | 653 hp / 480 kW | 850 Nm | Electro | not measured | not measured | not measured | not measured | Automatic, 1 | AWD |
| AT 100 kWh | 2022-12-01 | 653 hp / 480 kW | 850 Nm | Electro | not measured | not measured | not measured | not measured | Automatic, 1 | AWD |
Power match: 653 hp and 480 kW on both names. Torque match: 850 Nm on both. Drive match: AWD. Gearbox match: Automatic with 1 speed. Fuel match: Electro. Displacement, cylinders, layout, and boost are not measured on both — there is no litre figure to turn into “hp per litre,” so that ratio is not calculated.
What the later name actually changes in the table: start date only. AT 70 kWh is listed from 2022-03-01; AT 100 kWh from 2022-12-01. That is 9 months later on the calendar of the same generation, not a second generation.
Specs: same output, different pack name
If the question is “which engine,” the data do not split the two names by horsepower. AT 70 kWh is 653 hp / 480 kW and 850 Nm. AT 100 kWh is 653 hp / 480 kW and 850 Nm. Difference in power: 0 hp. Difference in torque: 0 Nm.
What you cannot use as a tie-break: cylinder count (not measured), cylinder layout (not measured), boost (not measured), displacement (not measured). Those fields are empty on both rows, so neither version is “the six-cylinder” or “the turbo” in this catalogue.
Gearbox and drive also do not split the buy: Automatic, 1 speed, AWD on AT 70 kWh and on AT 100 kWh.
The names themselves are the only pack split in the data: AT 70 kWh versus AT 100 kWh. Arithmetic on those name figures: 100 − 70 = 30 kWh more in the later name. That is a naming difference, not a second power rating.
Performance and economy: 0–100, top speed, mpg
| Version | 0–100 km/h | Top speed | City / highway / mixed use | CO₂ |
|---|---|---|---|---|
| AT 70 kWh | 3.9 s | not measured | not measured / not measured / not measured | 0 |
| AT 100 kWh | 3.8 s | 200 | not measured / not measured / not measured | 0 |
AT 100 kWh is 0.1 s quicker to 100 km/h than AT 70 kWh (3.8 versus 3.9). That is the only measured acceleration gap.
Top speed is published only for AT 100 kWh: 200. For AT 70 kWh top speed is not measured. Choosing the smaller pack because it is “slower at the top” is not supported — the figure is missing, not lower.
Fuel consumption (city, highway, mixed) is not measured on both versions. There is no mpg number to prefer one name over the other. CO₂ is 0 on AT 70 kWh and 0 on AT 100 kWh; the difference is 0.
Dimensions, weight, wheels, tank
| Version | Kerb weight | Gross weight | Ground clearance | Tank | Wheels |
|---|---|---|---|---|---|
| AT 70 kWh | not measured | not measured | not measured | not measured | not measured |
| AT 100 kWh | 2454 | not measured | not measured | not measured | 245/45 R20, 255/40 R21 |
Kerb weight is published only for AT 100 kWh: 2454. For AT 70 kWh kerb weight is not measured, so you cannot say the 70 pack is lighter from this table. Gross weight, ground clearance, and tank are not measured on both.
Weight per horsepower can be computed only where both numbers exist: AT 100 kWh is 2454 / 653 ≈ 3.76 kg per hp. For AT 70 kWh that ratio is not measured because mass is not measured.
Wheels are listed only on AT 100 kWh: 245/45 R20 and 255/40 R21. On AT 70 kWh wheel size is not measured. If you need a documented tyre size in this catalogue, the name that carries it is AT 100 kWh.
Front and rear suspension are the same wording on both: Independent, pneumatic. Front brakes: Ventilated disc on both. Rear brakes: Disc ventilated on both (label as in the data). Chassis hardware does not split the two names.
Which generation changed what
There is 1 generation, not a sequence of facelifts listed as extra generations. Body is Sedan for the whole run. Version count: 2.
What changed inside that generation is the second row, not a new generation number:
- AT 70 kWh opens the line on 2022-03-01 with 653 hp, 850 Nm, 3.9 s to 100 km/h, AWD, Automatic 1, CO₂ 0. Top speed, mass, wheels, tank, clearance, consumption: not measured.
- AT 100 kWh arrives 2022-12-01 with the same 653 hp, 850 Nm, AWD, Automatic 1, CO₂ 0, and a 3.8 s 0–100. Newly published in the data: top speed 200, kerb 2454, wheels 245/45 R20 and 255/40 R21.
No restyling is listed as a separate generation. Do not read “two generations” from two pack names.
Which version to choose
Choose AT 70 kWh if the start date that matters is 2022-03-01 and you accept that top speed, kerb weight, and wheel sizes are not measured for this name. You still get 653 hp, 850 Nm, AWD, Automatic 1, 3.9 s 0–100, and CO₂ 0. You do not get a documented 200 top speed or a documented 2454 kerb figure on this row.
Choose AT 100 kWh if you want the only row where those extra numbers exist: 3.8 s 0–100 (0.1 s quicker), top speed 200, kerb 2454, wheels 245/45 R20 and 255/40 R21, still 653 hp and 850 Nm. The pack name is 30 kWh higher than AT 70 kWh by the figures in the names. Start is 2022-12-01, 9 months after AT 70 kWh.
What extra money buys is not measured here — there are no prices. What the later name buys in this table is 0 hp more, 0 Nm more, 0.1 s less to 100 km/h, a published 200 top speed, a published 2454 kg kerb weight, and two wheel sizes. Consumption, tank, clearance, and gross weight stay not measured on both, so they cannot decide the purchase.
There is no third version and no second generation to pick. The Nio ET7 buy, on these numbers, is AT 70 kWh versus AT 100 kWh only.
