BMW i4 vs Mercedes-Benz EQS

Side-by-Side Specs

Charging Speed

The BMW i4 has the higher published DC charging figure at 205 kW, which is roughly 3% higher than the Mercedes-Benz EQS at 200 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 BMW i4 is listed at about 28 minutes, which is 5 minutes quicker than the Mercedes-Benz EQS at 33 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Mercedes-Benz EQS has a WLTP rated range of approximately 822 km, which is roughly 209 km more than the BMW i4 at approximately 613 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 172 Wh/km for the Mercedes-Benz EQS. 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 Mercedes-Benz EQS has approximately 118 kWh of useable battery , while the BMW i4 has approximately 81.3 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) and the shorter published charge time at approximately 28 minutes. For long road trips, published stop time matters more than the headline kW number alone.

For AC charging (home wallboxes, workplace chargers, and public street chargers), the Mercedes-Benz EQS supports up to 11 kW (22 kW optional), compared to up to 11 kW for the BMW i4. In Europe, many public chargers are 22 kW AC, so this difference can matter at those locations if the higher AC figure is fitted on the car you buy.

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 Mercedes-Benz EQS has a WLTP rated range of approximately 822 km, which is roughly 209 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
