BMW iX3 vs Mercedes-Benz EQE SUV

Side-by-Side Specs

Charging Speed

The BMW iX3 has the higher published DC charging figure at 400 kW, which is roughly 131% higher than the Mercedes-Benz EQE SUV at 173 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 iX3 is listed at about 21 minutes, which is 9 minutes quicker than the Mercedes-Benz EQE SUV at 30 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The BMW iX3 has a WLTP rated range of approximately 805 km, which is roughly 194 km more than the Mercedes-Benz EQE SUV at approximately 611 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 iX3 consumes 178 Wh/km, compared to 202 Wh/km for the Mercedes-Benz EQE SUV. That means the BMW iX3 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 iX3 has approximately 108.7 kWh of useable battery , while the Mercedes-Benz EQE SUV has approximately 96 kWh.

Which One Should You Choose?

If fast charging is your priority, the BMW iX3 has the higher published DC figure (up to 400 kW) and the shorter published charge time at approximately 21 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 EQE SUV supports up to 11 kW (22 kW optional), compared to up to 11 kW for the BMW iX3. 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 iX3 is the more efficient choice at 178 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the BMW iX3 has a WLTP rated range of approximately 805 km, which is roughly 194 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
