Mercedes-Benz EQS SUV vs Polestar 3

Side-by-Side Specs

Charging Speed

The Polestar 3 has the higher published DC charging figure at 250 kW, which is roughly 25% higher than the Mercedes-Benz EQS SUV 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 Polestar 3 is listed at about 32 minutes, which is 1 minutes quicker than the Mercedes-Benz EQS SUV at 33 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Mercedes-Benz EQS SUV has a WLTP rated range of approximately 720 km, which is roughly 14 km more than the Polestar 3 at approximately 706 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 Polestar 3 consumes 202 Wh/km, compared to 219 Wh/km for the Mercedes-Benz EQS SUV. That means the Polestar 3 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 SUV has approximately 118 kWh of useable battery , while the Polestar 3 has approximately 107 kWh.

Which One Should You Choose?

If fast charging is your priority, the Polestar 3 has the higher published DC figure (up to 250 kW) and the shorter published charge time at approximately 32 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 SUV supports up to 11 kW (22 kW optional), compared to up to 11 kW for the Polestar 3. 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 Polestar 3 is the more efficient choice at 202 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Mercedes-Benz EQS SUV has a WLTP rated range of approximately 720 km, which is roughly 14 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
