Quick verdict
The BMW i4 has the higher published DC charging figure at 205 kW, but both cars are listed at about 28 minutes for the published fast-charge window. The BMW i4 is more efficient at approximately 155 Wh/km. The BMW i4 offers more WLTP rated range at 613 km.
Side-by-Side Specs
| Spec | BMW i4 | Peugeot e-408 |
|---|---|---|
| Compared variant | eDrive40 | 58 kWh |
| Battery (approx.) | ~81.3 kWh | ~58.3 kWh |
| WLTP range (rated) | ~613 km | ~420 km |
| Efficiency (approx.) | ~155 Wh/km | ~164 Wh/km |
| DC fast charging (published) | up to 205 kW | up to 120 kW |
| 10-80% charge time (approx.) | ~28 min | ~28 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The BMW i4 has the higher published DC charging figure at 205 kW, which is roughly 71% higher than the Peugeot e-408 at 120 kW. In practice, that figure only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.
For the published fast-charge window, the Peugeot e-408 is listed at about 28 minutes, roughly matching the BMW i4. In this case, the headline kW number should not drive the decision by itself.
Range and Efficiency
The BMW i4 has a WLTP rated range of approximately 613 km, which is roughly 193 km more than the Peugeot e-408 at approximately 420 km. WLTP is a standardized lab test. Expect your actual range to be lower, varying with speed, weather, terrain, and driving style.
Efficiency matters more than battery size for daily driving costs. The BMW i4 consumes 155 Wh/km, compared to 164 Wh/km for the Peugeot e-408. That means the BMW i4 uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.
A more efficient car does not always mean more range. Battery size plays a role too. The BMW i4 has approximately 81.3 kWh of useable battery , while the Peugeot e-408 has approximately 58.3 kWh.
Which One Should You Choose?
If fast charging is your priority, the BMW i4 has the higher published DC figure (up to 205 kW), but both cars are listed at approximately 28 minutes for the published fast-charge window. For long road trips, published stop time matters more than the headline kW number alone.
Both cars support 11 kW AC charging, so home and workplace charging speeds will be similar.
If you mostly charge at home or at work and care more about daily driving costs, the BMW i4 is the more efficient choice at 155 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BMW i4 has a WLTP rated range of approximately 613 km, which is roughly 193 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.

From Finn, engineer: Charging specs alone do not tell the full story. Real-world charging speed depends on battery temperature, state of charge, and the charger itself. These comparisons use manufacturer-published data. Approximate values only.
