Lexus RZ vs Mercedes-Benz GLC Electric

Side-by-Side Specs

Charging Speed

The Mercedes-Benz GLC Electric has the higher published DC charging figure at 330 kW, which is roughly 120% higher than the Lexus RZ at 150 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 GLC Electric is listed at about 22 minutes, which is 8 minutes quicker than the Lexus RZ at 30 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Mercedes-Benz GLC Electric has a WLTP rated range of approximately 715 km, which is roughly 140 km more than the Lexus RZ at approximately 575 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 Lexus RZ consumes 180 Wh/km, compared to 188 Wh/km for the Mercedes-Benz GLC Electric. That means the Lexus RZ 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 GLC Electric has approximately 94 kWh of useable battery , while the Lexus RZ has approximately 72 kWh.

Which One Should You Choose?

If fast charging is your priority, the Mercedes-Benz GLC Electric has the higher published DC figure (up to 330 kW) and the shorter published charge time at approximately 22 minutes. For long road trips, published stop time matters more than the headline kW number alone.

Both cars support 22 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 Lexus RZ is the more efficient choice at 180 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Mercedes-Benz GLC Electric has a WLTP rated range of approximately 715 km, which is roughly 140 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
