Mercedes-Benz CLA Electric vs Mercedes-Benz EQS

Side-by-Side Specs

Charging Speed

The Mercedes-Benz CLA Electric has the higher published DC charging figure at 353 kW, which is roughly 77% 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 Mercedes-Benz CLA Electric is listed at about 18 minutes, which is 15 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 30 km more than the Mercedes-Benz CLA Electric at approximately 792 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 Mercedes-Benz CLA Electric consumes 145 Wh/km, compared to 172 Wh/km for the Mercedes-Benz EQS. That means the Mercedes-Benz CLA Electric 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 Mercedes-Benz CLA Electric has approximately 85 kWh.

Which One Should You Choose?

If fast charging is your priority, the Mercedes-Benz CLA Electric has the higher published DC figure (up to 353 kW) and the shorter published charge time at approximately 18 minutes. 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 Mercedes-Benz CLA Electric is the more efficient choice at 145 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 30 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
