VinFast VF9: which version to buy and why (AT 92 kWh vs AT 123 kWh)
The VinFast VF9 has one generation, in production from 2022-11-01 with no end date in the data, as an SUV 5-doors with two versions: AT 92 kWh and AT 123 kWh. Both make 408 hp (300 kW) and both reach 100 km/h in 6.3 s on AWD with a 1-speed Automatic. The choice is not “which generation” and not “which engine type”: both are Electro.
The VinFast VF9 has one generation, in production from 2022-11-01 with no end date in the data, as an SUV 5-doors with two versions: AT 92 kWh and AT 123 kWh. Both make 408 hp (300 kW) and both reach 100 km/h in 6.3 s on AWD with a 1-speed Automatic. The choice is not “which generation” and not “which engine type”: both are Electro. The measured differences are battery energy (92 kWh vs 123 kWh) and peak torque (620 Nm vs 652 Nm). Everything else that is listed is either identical or not measured.
Which VF9 version: AT 92 kWh or AT 123 kWh
AT 123 kWh is the higher-energy, higher-torque VF9. It stores 31 kWh more than AT 92 kWh (123 − 92 = 31 kWh, about 33.7% more pack energy) and makes 32 Nm more peak torque (652 − 620 = 32 Nm, about 5.2% more). Power does not rise: both are 408 hp and 300 kW. Acceleration to 100 km/h does not change: both are 6.3 s. Drive, gearbox type, and gear count do not change: AWD, Automatic, 1 speed.
If the extra 31 kWh is the reason you are shopping the VF9, AT 123 kWh is the version that actually differs on the sheet. If 408 hp, 6.3 s, AWD, and the same chassis labels are enough, AT 92 kWh is the same car on power and sprint, with 92 kWh instead of 123 kWh and 620 Nm instead of 652 Nm.
There is no third VF9 version in the data and no later generation to “wait for” inside this catalogue entry.
Generations: what changed (and what did not)
VinFast VF9 has 1 generation (key 7119), labelled 1 generation, from 2022-11-01, still open (stop not measured). Body for this generation: SUV 5-doors. Version count: 2.
There is no restyling listed as a separate generation, and there is no second generation to compare year-over-year. Arithmetic between generations is not possible: there is only one. The only comparison that exists is between the two versions of this generation.
Both versions of 1 generation start on 2022-11-01 and have stop not measured. You are not choosing a 2022 car versus a later facelift in this dataset; you are choosing AT 92 kWh versus AT 123 kWh on the same start date.
Specs table: VF9 engine, gearbox, and drive by version
Displacement, cylinders, cylinder layout, and boost are not measured for either Electro version. Fuel is Electro. Gearbox is Automatic with 1 speed. Drive is AWD.
| Version | hp | kW | Nm | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Speeds | Drive |
|---|---|---|---|---|---|---|---|---|---|---|---|
| AT 92 kWh | 408 | 300 | 620 | not measured | Electro | not measured | not measured | not measured | Automatic | 1 | AWD |
| AT 123 kWh | 408 | 300 | 652 | not measured | Electro | not measured | not measured | not measured | Automatic | 1 | AWD |
Same hp, same kW, same fuel label, same gearbox, same drive. The only numeric engine-side gap in the table is torque: AT 123 kWh 652 Nm versus AT 92 kWh 620 Nm.
Power density against pack energy (allowed arithmetic on given numbers):
- AT 92 kWh: 408 hp / 92 kWh ≈ 4.43 hp per kWh; 300 kW / 92 kWh ≈ 3.26 kW per kWh; 620 Nm / 92 kWh ≈ 6.74 Nm per kWh.
- AT 123 kWh: 408 hp / 123 kWh ≈ 3.32 hp per kWh; 300 kW / 123 kWh ≈ 2.44 kW per kWh; 652 Nm / 123 kWh ≈ 5.30 Nm per kWh.
AT 92 kWh is the denser pack on paper: more horsepower, more kilowatts, and more newton-metres per stored kWh. AT 123 kWh is the larger store: 31 kWh extra, with only 32 Nm extra torque and zero extra horsepower. If you want peak output per unit of battery energy, the numbers favour AT 92 kWh. If you want the larger energy figure itself, they favour AT 123 kWh.
Torque per horsepower (same 408 hp on both):
- AT 92 kWh: 620 / 408 ≈ 1.52 Nm per hp.
- AT 123 kWh: 652 / 408 ≈ 1.60 Nm per hp.
The larger pack version is slightly more torque-rich at the same peak power. That is a 32 Nm gap on a 408 hp car, not a second motor specification.
Performance: 0–100, top speed, mpg
| Version | 0–100 km/h (s) | Top speed | City use | Highway use | Combined use / mpg |
|---|---|---|---|---|---|
| AT 92 kWh | 6.3 | not measured | not measured | not measured | not measured |
| AT 123 kWh | 6.3 | not measured | not measured | not measured | not measured |
Sprint is a tie: 6.3 s for AT 92 kWh and 6.3 s for AT 123 kWh. The extra 32 Nm and extra 31 kWh on AT 123 kWh do not show up as a quicker 0–100 in this data. Top speed is not measured for either version, so you cannot pick the “faster” VF9 on a maximum-speed number.
Fuel consumption and mpg are not measured for either Electro version (city not measured, highway not measured, combined not measured). There is no mpg ranking between AT 92 kWh and AT 123 kWh in this catalogue. CO2 is not measured. Eco class is not measured. A buyer who needs a published consumption or mpg figure will not find one here for either version.
What you can say without inventing economy: AT 123 kWh has 123 / 92 ≈ 1.337 times the listed pack energy of AT 92 kWh. That is a pack-size ratio, not a range or mpg figure. Range itself is not in the data.
Dimensions, weight, tank, wheels, chassis
Kerb weight is not measured for AT 92 kWh and not measured for AT 123 kWh. Gross weight is not measured for both. Ground clearance is not measured for both. Tank is not measured (Electro, no fuel-tank figure). Wheel sizes are not measured for both.
Weight per horsepower cannot be calculated: mass is not measured, so “which VF9 is lighter per hp” is not a number this dataset supports. Do not treat the larger 123 kWh pack as a proven weight penalty or the 92 kWh pack as a proven weight win; kerb mass is not measured.
Chassis labels that are measured are the same on both versions:
- Front suspension: Independent, pneumatic (AT 92 kWh and AT 123 kWh).
- Rear suspension: Independent, spring (AT 92 kWh and AT 123 kWh).
- Front brakes: Ventilated disc (AT 92 kWh and AT 123 kWh).
- Rear brakes: Disc (AT 92 kWh and AT 123 kWh).
You are not choosing a VF9 with a different axle layout, a different brake type, or a different suspension recipe. The chassis wording does not split the two versions.
What the extra energy buys (arithmetic, no prices)
There are no prices in the data, so “extra money” is not a currency amount. The extra specification on AT 123 kWh versus AT 92 kWh is:
1. +31 kWh pack energy (123 vs 92). 2. +32 Nm peak torque (652 vs 620). 3. +0 hp (408 vs 408). 4. +0 kW (300 vs 300). 5. +0.0 s on 0–100 (6.3 vs 6.3 — no improvement listed). 6. Same Automatic, 1 speed, AWD. 7. Same Independent, pneumatic front and Independent, spring rear. 8. Same Ventilated disc front and Disc rear.
Per extra kWh, the torque gain is 32 Nm / 31 kWh ≈ 1.03 Nm per extra kWh. Per extra kWh, the power gain is 0 hp. If you buy AT 123 kWh expecting a stronger peak-power VF9, the sheet does not support that: power is tied. If you buy it expecting a quicker 0–100, the sheet does not support that either: 6.3 s on both.
If you buy AT 92 kWh expecting a weaker motor, that is also wrong on peak power: 408 hp and 300 kW match AT 123 kWh. You give up 32 Nm and 31 kWh, not 408 hp.
Reliability and problems
Reliability, common problems, recall counts, and warranty terms are not measured in this dataset for AT 92 kWh or AT 123 kWh. Do not infer that the 92 kWh pack is more or less reliable than the 123 kWh pack from these numbers. The only version-level facts that differ remain energy and torque.
Decision rule using only these numbers
Choose AT 123 kWh when the 123 kWh energy figure is the reason you want this SUV 5-doors, and you also want the 652 Nm peak rather than 620 Nm. You do not get more than 408 hp, you do not get a different 0–100 than 6.3 s, and you do not get a second generation.
Choose AT 92 kWh when 92 kWh is enough energy on the sheet and you want the same 408 hp, same 300 kW, same 6.3 s, same AWD, same 1-speed Automatic, and the same suspension and brake labels, with 620 Nm instead of 652 Nm. This version has the higher hp-per-kWh and kW-per-kWh ratios (≈ 4.43 hp/kWh and ≈ 3.26 kW/kWh versus ≈ 3.32 hp/kWh and ≈ 2.44 kW/kWh).
Do not choose by generation: VinFast VF9 1 generation is the only generation, from 2022-11-01, SUV 5-doors, two versions.
Do not choose by mpg, top speed, kerb weight, gross weight, ground clearance, tank, or wheels: all of those are not measured for AT 92 kWh and not measured for AT 123 kWh.
Do not choose by cylinder count, displacement, layout, or boost: those are not measured on this Electro pair.
Names to keep exact when you open a modification page: AT 92 kWh and AT 123 kWh. Both are 408 hp, so they are not split by horsepower; they are split by pack energy and by 620 Nm versus 652 Nm.
