IM IM5: Which Version Should You Buy?
The IM IM5 range comprises three electric Liftback versions from a single generation that entered production in September 2025. The choice is chiefly between the lighter AT 75 kWh with 295 hp and RWD, the stronger AT 100 kWh with 408 hp and RWD, and a performance-focused AT 100 kWh with 777 hp and AWD.
The IM IM5 range comprises three electric Liftback versions from a single generation that entered production in September 2025.

For most buyers prioritizing performance without moving to the heaviest version, the 408 hp AT 100 kWh offers the middle ground: it reaches 100 km/h in 4.9 seconds, has a 220 km/h top speed, and weighs 2,210 kg. Buyers seeking the quickest IM5 should choose the 777 hp AT 100 kWh, while the 295 hp AT 75 kWh is the least powerful, slowest, and lightest option.
IM Motors IM5 versions compared
All three IM IM5 modifications use Electro power, an Automatic gearbox with 1 ratio, independent spring suspension at both ends, and ventilated disc brakes front and rear. The two versions called AT 100 kWh must be distinguished by output and drive: one produces 408 hp with RWD, while the other produces 777 hp with AWD.
| Version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| AT 75 kWh | 295 hp / 216 kW | 450 Nm | not measured | Electro | not measured | not measured | not measured | Automatic, 1 | RWD |
| AT 100 kWh — 408 hp | 408 hp / 300 kW | 500 Nm | not measured | Electro | not measured | not measured | not measured | Automatic, 1 | RWD |
| AT 100 kWh — 777 hp | 777 hp / 571 kW | 802 Nm | not measured | Electro | not measured | not measured | not measured | Automatic, 1 | AWD |
The 408 hp AT 100 kWh adds 113 hp and 50 Nm over the AT 75 kWh, while increasing kerb weight by only 30 kg. The 777 hp AT 100 kWh adds a further 369 hp and 302 Nm over the 408 hp version, together with AWD and another 70 kg of kerb weight.
Power per litre cannot be calculated for any IM5 version because engine displacement is not measured. Weight per horsepower is more informative here: the AT 75 kWh carries approximately 7.39 kg per hp, the 408 hp AT 100 kWh about 5.42 kg per hp, and the 777 hp AT 100 kWh about 2.93 kg per hp.
IM IM5 performance: acceleration and top speed
| Version | 0–100 km/h | Top speed | Fuel consumption |
|---|---|---|---|
| AT 75 kWh | 6.8 seconds | 200 km/h | City: not measured; highway: not measured; combined: not measured |
| AT 100 kWh — 408 hp | 4.9 seconds | 220 km/h | City: not measured; highway: not measured; combined: not measured |
| AT 100 kWh — 777 hp | 3.2 seconds | 268 km/h | City: not measured; highway: not measured; combined: not measured |
Moving from the AT 75 kWh to the 408 hp AT 100 kWh cuts 1.9 seconds from the 0–100 km/h time and raises top speed by 20 km/h. Moving from the 408 hp AT 100 kWh to the 777 hp version removes another 1.7 seconds and adds 48 km/h to the maximum speed.
Across the full range, the 777 hp AT 100 kWh is 3.6 seconds quicker to 100 km/h and has a top speed 68 km/h higher than the AT 75 kWh. No city, highway, or combined consumption figure is measured for any version, so the data does not support an economy ranking.
IM Motors IM5 dimensions, weight, and wheels
| Version | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|
| AT 75 kWh | 2,180 kg | 2,610 kg | not measured | not measured | 245/45 R19 front; 275/40 R19 rear |
| AT 100 kWh — 408 hp | 2,210 kg | 2,640 kg | not measured | not measured | 245/40 R20 front; 275/35 R20 rear |
| AT 100 kWh — 777 hp | 2,280 kg | 2,730 kg | not measured | not measured | 245/40 R20 front; 275/35 R20 rear |
The AT 75 kWh is the lightest IM5 at 2,180 kg. The 408 hp AT 100 kWh weighs 30 kg more, and the 777 hp AT 100 kWh weighs 100 kg more than the AT 75 kWh. Gross weight rises from 2,610 kg through 2,640 kg to 2,730 kg.
Both AT 100 kWh versions share the same listed staggered wheel sizes: 245/40 R20 at the front and 275/35 R20 at the rear. The AT 75 kWh uses 245/45 R19 front and 275/40 R19 rear sizes. Ground clearance and tank capacity are not measured for any version.
IM5 generations: is there an older version to consider?
There is only one IM IM5 generation in the supplied data. It began production in September 2025, uses a Liftback body, and contains three versions. There is therefore no previous generation to compare for changes in power, acceleration, drive, weight, body style, or specifications.
Which IM IM5 version should you buy?
Choose the AT 75 kWh if the lightest listed IM5 and RWD are your priorities. Its 295 hp, 450 Nm, 6.8-second acceleration time, and 200 km/h maximum make it the least performance-oriented version, but it is also 30 kg lighter than the 408 hp model and 100 kg lighter than the 777 hp model. It is the only version fitted with the listed 19-inch wheel sizes.
Choose the 408 hp AT 100 kWh if you want the strongest numerical compromise. Compared with the AT 75 kWh, it provides 113 hp more, 50 Nm more, a 1.9-second quicker sprint to 100 km/h, and a 20 km/h higher top speed for a 30 kg increase in kerb weight. It retains RWD and uses the listed 20-inch wheel sizes.
Choose the 777 hp AT 100 kWh if acceleration, maximum speed, torque, and AWD matter most. It leads the range with 777 hp, 802 Nm, a 3.2-second 0–100 km/h time, and a 268 km/h top speed. The trade-off visible in the data is weight: at 2,280 kg kerb and 2,730 kg gross, it is the heaviest IM5 version.
A value-for-money judgment cannot be made because IM IM5 prices are not measured. Economy, range, charging performance, interior equipment, ground clearance, and reliability are also not measured, so none should be used to declare one version objectively superior. Based strictly on the available specifications, the 408 hp AT 100 kWh is the balanced performance choice, the AT 75 kWh is the lighter and less powerful choice, and the 777 hp AT 100 kWh is the unequivocal performance choice.
