IM Motors IM6: which version to buy
If the question is which IM6 to buy, the first generation (from 2023-10-01, still in production, body SUV Coupe, three versions) answers it with three electric drivetrains that share the same wheels, clearance, and one-speed Automatic gearbox. The 75 kWh is the lightest and least powerful rear-drive car.
If the question is which IM6 to buy, the first generation (from 2023-10-01, still in production, body SUV Coupe, three versions) answers it with three electric drivetrains that share the same wheels, clearance, and one-speed Automatic gearbox. The 75 kWh is the lightest and least powerful rear-drive car. The two versions both named 100 kWh are not the same car: one is 408 hp RWD, the other is 777 hp AWD. Range, interior size, and price are not measured in this dataset, so they cannot decide the purchase here. Power, torque, 0–100 km/h, top speed, and weight can.
IM6 generations: what actually changed
There is one generation. It started on 2023-10-01, has no end date in the data, uses the SUV Coupe body, and lists three versions. There is no restyling recorded as a separate generation, and there is no second generation to compare against. IM5 vs IM6, IM LS6 vs IM6, IM LS7 vs IM6, and IM6 vs IM7 are searches people make; those other models are not in this dataset, so they are not used as facts. Within the IM6 itself, every difference that can be counted is a difference between the three versions of this one generation.
IM6 specs: engines, gearbox, and drive
Displacement, cylinders, cylinder layout, and boost are not measured for any IM6 version (all three are Electro). Power per litre therefore cannot be calculated. What can be compared is output, torque, the Automatic 1-speed gearbox, and drive.
| Version | hp | kW | Nm | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Speeds | Drive |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 75 kWh | 295 | 216 | 450 | not measured | Electro | not measured | not measured | not measured | Automatic | 1 | RWD |
| 100 kWh (408 hp) | 408 | 300 | 500 | not measured | Electro | not measured | not measured | not measured | Automatic | 1 | RWD |
| 100 kWh (777 hp) | 777 | 571 | 802 | not measured | Electro | not measured | not measured | not measured | Automatic | 1 | AWD |
The two 100 kWh rows must stay named 100 kWh. They are separated by power: 408 hp versus 777 hp. Treating them as one version would hide a 369 hp gap (777 − 408) and a change of drive from RWD to AWD.
Relative to the 75 kWh (295 hp, 216 kW, 450 Nm, RWD):
- 100 kWh (408 hp) adds 113 hp (408 − 295), 84 kW (300 − 216), and 50 Nm (500 − 450). Drive stays RWD. Gearbox stays Automatic, 1 speed.
- 100 kWh (777 hp) adds 482 hp (777 − 295), 355 kW (571 − 216), and 352 Nm (802 − 450). Drive changes from RWD to AWD.
Relative to 100 kWh (408 hp), 100 kWh (777 hp) adds 369 hp, 271 kW (571 − 300), and 302 Nm (802 − 500), and is the only AWD IM6 in the data.
IM6 performance: 0–100, top speed, and economy
Fuel consumption (city, highway, mixed) is not measured for 75 kWh, 100 kWh (408 hp), or 100 kWh (777 hp). Tank capacity is not measured. Those figures cannot rank the versions. Acceleration and top speed can.
| Version | 0–100 km/h (s) | Top speed (km/h) | City | Highway | Mixed | CO2 |
|---|---|---|---|---|---|---|
| 75 kWh | 6.8 | 235 | not measured | not measured | not measured | not measured |
| 100 kWh (408 hp) | 5.4 | 235 | not measured | not measured | not measured | 0 |
| 100 kWh (777 hp) | 3.4 | 239 | not measured | not measured | not measured | 0 |
100 kWh (408 hp) reaches 100 km/h 1.4 s sooner than 75 kWh (6.8 − 5.4). Top speed is the same: 235 km/h. The extra 113 hp and 50 Nm buy a shorter sprint, not a higher listed maximum.
100 kWh (777 hp) reaches 100 km/h 2.0 s sooner than 100 kWh (408 hp) (5.4 − 3.4) and 3.4 s sooner than 75 kWh (6.8 − 3.4). Top speed is 239 km/h: 4 km/h above the other two (239 − 235). That is the only top-speed gap in the catalogue.
CO2 is 0 for both 100 kWh versions and not measured for 75 kWh. That is not a ranking of “cleaner” cars; it is a gap in the 75 kWh row.
IM6 dimensions, weight, and wheels
Body exterior dimensions (length, width, height, wheelbase) are not measured. What is measured is kerb weight, gross weight, ground clearance, and wheels.
| Version | Kerb (kg) | Gross (kg) | Clearance (mm) | Tank | Wheels |
|---|---|---|---|---|---|
| 75 kWh | 2280 | 2731 | 161 | not measured | 235/45 R21, 265/40 R21 |
| 100 kWh (408 hp) | 2350 | 2771 | 161 | not measured | 235/45 R21, 265/40 R21 |
| 100 kWh (777 hp) | 2445 | 2861 | 161 | not measured | 235/45 R21, 265/40 R21 |
Clearance is 161 mm on all three. Wheels are 235/45 R21 and 265/40 R21 on all three. Front and rear suspension are Independent, spring on all three. Front brakes are Ventilated disc; rear brakes are Disc ventilated — the same labels on every version. The chassis specification does not pick a winner.
Weight does.
- 100 kWh (408 hp) is 70 kg heavier at the kerb than 75 kWh (2350 − 2280) and 40 kg heavier gross (2771 − 2731).
- 100 kWh (777 hp) is 95 kg heavier at the kerb than 100 kWh (408 hp) (2445 − 2350) and 90 kg heavier gross (2861 − 2771).
- 100 kWh (777 hp) is 165 kg heavier at the kerb than 75 kWh (2445 − 2280) and 130 kg heavier gross (2861 − 2731).
Kilograms per horsepower (kerb ÷ hp):
- 75 kWh: 2280 ÷ 295 ≈ 7.73 kg/hp
- 100 kWh (408 hp): 2350 ÷ 408 ≈ 5.76 kg/hp
- 100 kWh (777 hp): 2445 ÷ 777 ≈ 3.15 kg/hp
The AWD 100 kWh carries the most mass and still has the lowest mass per horsepower. The 75 kWh is the lightest car and the heaviest per horsepower. Payload implied by gross minus kerb:
- 75 kWh: 2731 − 2280 = 451 kg
- 100 kWh (408 hp): 2771 − 2350 = 421 kg
- 100 kWh (777 hp): 2861 − 2445 = 416 kg
The lightest version has the largest listed payload gap (451 − 416 = 35 kg versus the 777 hp car). That is arithmetic on the two mass figures, not a cargo-volume measurement — cargo volume is not measured.
Which IM6 version to choose
There is no second generation, so “which generation” is already answered: first generation, SUV Coupe, from 2023-10-01. The buy decision is which of the three Electro versions matches the job.
Choose 75 kWh if the priority is the lowest listed mass and you accept the longest 0–100. It is 295 hp, 216 kW, 450 Nm, Automatic 1-speed, RWD. Kerb 2280 kg, gross 2731 kg. 0–100 is 6.8 s; top speed 235 km/h. Versus 100 kWh (408 hp) you give up 113 hp, 50 Nm, and 1.4 s to 100 km/h, and you save 70 kg at the kerb. Versus 100 kWh (777 hp) you give up 482 hp, 352 Nm, AWD, 3.4 s to 100 km/h, and 4 km/h of top speed, and you save 165 kg. City, highway, and mixed consumption are not measured; range is not measured. CO2 is not measured on this version. If those missing figures are what you wanted to use as a buying filter, this dataset cannot supply them.
Choose 100 kWh (408 hp) if you want the larger battery name with rear drive and a mid pack on the stopwatch. It is 408 hp, 300 kW, 500 Nm, Automatic 1-speed, RWD. Kerb 2350 kg, gross 2771 kg. 0–100 is 5.4 s; top speed 235 km/h; CO2 0. It is the middle of the three on power, torque, acceleration, and weight. It is not the middle on drive: like the 75 kWh, it is RWD, not AWD. It does not raise top speed above the 75 kWh. What the step up from 75 kWh buys, in numbers, is +113 hp, +50 Nm, −1.4 s to 100 km/h, +70 kg kerb, +40 kg gross. What it does not buy is AWD, a higher 235 km/h cap, different wheels, or different clearance.
Choose 100 kWh (777 hp) if the purchase is for IM6 performance and AWD. It is 777 hp, 571 kW, 802 Nm, Automatic 1-speed, AWD. Kerb 2445 kg, gross 2861 kg. 0–100 is 3.4 s; top speed 239 km/h; CO2 0. It is the only AWD IM6 here. Versus 100 kWh (408 hp) it adds 369 hp, 302 Nm, AWD, 2.0 s off the 0–100, 4 km/h on top speed, 95 kg kerb, and 90 kg gross. Versus 75 kWh those gaps are 482 hp, 352 Nm, AWD, 3.4 s, 4 km/h, 165 kg, and 130 kg. Mass per horsepower falls from about 7.73 kg/hp on the 75 kWh to about 3.15 kg/hp here. Wheels stay 235/45 R21 and 265/40 R21; clearance stays 161 mm; the gearbox stays Automatic, 1 speed. The extra output is not a different chassis spec in this table — it is more power, more torque, AWD, a shorter sprint, a 4 km/h higher cap, and more weight.
A short filter that stays inside the data:
1. Need AWD → only 100 kWh (777 hp). The other two are RWD. 2. Need the shortest 0–100 → 100 kWh (777 hp) at 3.4 s. Next is 100 kWh (408 hp) at 5.4 s. Last is 75 kWh at 6.8 s. 3. Need the highest listed top speed → 100 kWh (777 hp) at 239 km/h. The other two are tied at 235 km/h. 4. Need the lowest kerb weight → 75 kWh at 2280 kg. 5. Need RWD with the stronger of the two rear-drive outputs → 100 kWh (408 hp), not 75 kWh. 6. Need a measured mixed consumption or tank size to pick an IM6 for economy → not measured on any version; that filter has no winner here. 7. Need IM6 dimensions (length/width/height) to compare with IM5, IM7, LS6, or LS7 → those exterior figures are not measured in this dataset.
Reliability, problems, interior, Australia, Sri Lanka, 2026 facelifts, and price are frequent searches. They are not facts in the launch data. The three version names to keep as anchors are 75 kWh, 100 kWh (408 hp), and 100 kWh (777 hp). If two pages both say only “100 kWh”, they will collide; the horsepower is what keeps them apart.
