Yudo JY AIR: which version to buy
The Yudo JY AIR is a one-generation electric Sedan sold from December 2024 with two catalogue versions: AT 64 kWh and AT 51 kWh. Both use the same 202 hp (148 kW) electric motor, the same 250 Nm, the same Automatic 1-speed gearbox, the same RWD layout, the same 7.9 s 0–100 figure, and the same 170 km/h top speed.
The Yudo JY AIR is a one-generation electric Sedan sold from December 2024 with two catalogue versions: AT 64 kWh and AT 51 kWh. Both use the same 202 hp (148 kW) electric motor, the same 250 Nm, the same Automatic 1-speed gearbox, the same RWD layout, the same 7.9 s 0–100 figure, and the same 170 km/h top speed. The only numbered difference between the two versions is battery size: 64 kWh versus 51 kWh. That 13 kWh gap — 25.5% more energy on the larger pack — is the whole buying decision.
There is no second generation to compare, no restyling year in the data, and no petrol or hybrid branch. Choosing a JY AIR is not a choice of body, drivetrain, or power. It is a choice of how much stored energy you pay for while the rest of the car stays the same.
JY AIR versions compared: AT 64 kWh vs AT 51 kWh
Both versions started in December 2024 and remain in production. Both are Sedan. Both are Electro. Both list CO2 at 0. Neither has a measured kerb weight, gross weight, ground clearance, wheel size, or energy use. Rear brakes are not measured on either version. Front brakes are Disc on both. Front and rear suspension are Independent, spring on both.
| Version | hp | kW | Nm | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Speeds | Drive |
|---|---|---|---|---|---|---|---|---|---|---|---|
| AT 64 kWh | 202 | 148 | 250 | not measured | Electro | not measured | not measured | not measured | Automatic | 1 | RWD |
| AT 51 kWh | 202 | 148 | 250 | not measured | Electro | not measured | not measured | not measured | Automatic | 1 | RWD |
Power is identical: 202 hp and 148 kW on AT 64 kWh and on AT 51 kWh. Torque is identical: 250 Nm on both. There is no displacement figure because both are Electro; the field is not measured, not a petrol litre count. Cylinders, cylinder layout, and boost are not measured on either version — they are not hidden petrol specs.
Gearbox and drive do not split the range either. AT 64 kWh is Automatic, 1 speed, RWD. AT 51 kWh is Automatic, 1 speed, RWD. You do not buy extra driven wheels or extra ratios by moving up a version.
What the extra 13 kWh actually buys
AT 64 kWh stores 64 kWh. AT 51 kWh stores 51 kWh. Difference: 13 kWh.
Relative to the smaller pack, 13 / 51 = 0.255, so AT 64 kWh holds 25.5% more energy. Relative to the larger pack, 13 / 64 = 0.203, so AT 51 kWh holds 20.3% less.
That is the only arithmetic the catalogue supports. Range, charging time, and consumption are not measured for either version, so a buyer cannot convert those 13 kWh into kilometres from this dataset. What can be said without inventing numbers:
- If you need the larger energy store, AT 64 kWh is the only JY AIR that has it.
- If 51 kWh is enough for the trips you actually do, AT 51 kWh gives the same 202 hp, the same 250 Nm, the same 7.9 s 0–100, and the same 170 km/h, with 13 kWh less onboard energy.
- There is no third pack size. There is no all-wheel-drive JY AIR. There is no higher-output JY AIR.
Power does not scale with the pack. 202 hp on 64 kWh and 202 hp on 51 kWh means the motor rating is not tied to which battery you pick. Torque does not scale either: 250 Nm on both. Acceleration does not scale: 7.9 s to 100 on both. Top speed does not scale: 170 km/h on both. The extra energy on AT 64 kWh is not extra performance in this table.
Performance: same stopwatch, same top speed
0–100 is 7.9 s for AT 64 kWh and 7.9 s for AT 51 kWh. Difference: 0.0 s.
Top speed is 170 km/h for AT 64 kWh and 170 km/h for AT 51 kWh. Difference: 0 km/h.
If the buying question is “which JY AIR is quicker,” the data answer is neither. The two versions are the same car on a stopwatch. If the buying question is “which JY AIR goes faster on a motorway,” the data answer is the same: both are limited to 170 km/h in the catalogue.
City consumption is not measured for AT 64 kWh. Highway consumption is not measured. Combined consumption is not measured. The same three fields are not measured for AT 51 kWh. There is no mpg figure, no kWh/100 km figure, and no way to rank economy between versions from this dataset. CO2 is 0 on both; that does not rank one version above the other.
Tank capacity is not measured on either version, which is consistent with Electro and with no liquid-fuel tank in the data. You cannot use tank size to choose.
Dimensions, weight, and chassis: nothing splits the two
Kerb weight is not measured for AT 64 kWh and not measured for AT 51 kWh. Gross weight is not measured for either. Ground clearance is not measured for either. Wheel sizes are not measured for either.
Because weight is not measured, weight per horsepower cannot be calculated. Because displacement is not measured, power per litre cannot be calculated. Those two classic ICE ratios are not available here and should not be invented.
What is measured on the chassis is the same on both versions:
- Front suspension: Independent, spring (AT 64 kWh and AT 51 kWh)
- Rear suspension: Independent, spring (AT 64 kWh and AT 51 kWh)
- Front brakes: Disc (AT 64 kWh and AT 51 kWh)
- Rear brakes: not measured (AT 64 kWh and AT 51 kWh)
You do not get a different suspension layout or a different named front brake type by choosing the larger battery. Clearance, wheels, and mass — the usual reasons one version “feels” different on paper — are not measured, so they cannot be used as a tie-breaker.
Generations: there is only one, and it did not split the powertrain
JY AIR has 1 generation. Production of that generation starts December 2024. Stop is not set. Body is Sedan. Version count is 2: AT 64 kWh and AT 51 kWh.
There is no earlier generation with a smaller motor, a different drive, or a different gearbox to “upgrade from.” There is no later generation that added power or all-wheel drive. A buyer in this catalogue is not choosing between a first-gen JY AIR and a second-gen JY AIR. Both named versions sit in the same generation, the same start date, and the same body.
That matters for the “which year / which generation” search. For JY AIR, generation does not change the answer. The answer stays inside generation 1: larger pack or smaller pack.
Which JY AIR version to choose
Choose AT 64 kWh if the 13 kWh is the point. It is the only version with 64 kWh. It still has 202 hp, 148 kW, 250 Nm, Automatic 1-speed, RWD, 7.9 s 0–100, 170 km/h, Electro, and CO2 0. You are not buying more horsepower. You are buying 25.5% more named battery energy than AT 51 kWh.
Choose AT 51 kWh if 51 kWh covers the use and you do not need the extra 13 kWh. It is not a weaker motor: 202 hp and 250 Nm match AT 64 kWh exactly. It is not a slower car on the catalogue stopwatch: 7.9 s and 170 km/h match exactly. It is the same Automatic 1-speed RWD Sedan with Independent, spring suspension front and rear and Disc front brakes. What you give up is 13 kWh of pack size, 20.3% of the larger pack’s energy.
Do not choose between them on power, torque, gearbox, drive, 0–100, or top speed. Those fields are equal. Do not choose on mpg, kerb weight, clearance, or wheels. Those fields are not measured on either version.
There is no “hot” JY AIR and no AWD JY AIR in this data. If the requirement is more than 202 hp, more than 250 Nm, a gearbox other than Automatic 1-speed, or a drive other than RWD, this model’s two versions do not provide it.

Reliability, problems, mpg
Reliability and known problems are not in the supplied data, so they cannot rank AT 64 kWh against AT 51 kWh. Mpg and energy use are not measured. Dimensions that would feed a “which is lighter / which sits higher” choice are not measured. The only comparison that stays inside the numbers is pack size: 64 kWh versus 51 kWh, same 202 hp electric Sedan, same Automatic RWD, same 7.9 s and 170 km/h.
