Performance
The Mercedes GT 55 4-Door Coupé 4MATIC+ has a maximum power of 375 kW (510 hp / 503 bhp) and a total torque of 1800 Nm (1328 lb-ft). It accelerates from 0 to 100 km/h (0 to 62 mph) in 2.8 seconds and reaches a top speed of 300 km/h (186 mph).
Battery, Range, and Charging
The battery has a gross capacity of 114.0 kWh and a net usable capacity of 106.0 kWh, with a 8.0 kWh buffer (7.0%) for battery protection. The battery operates at a nominal voltage of 800 V, supporting high-power DC charging.
Under the WLTP (Worldwide Harmonized Light Vehicles Test Procedure) standard, the maximum rated range is 700 km (435 miles). Depending on the configuration and options such as wheel size, the rated range can be as low as 597 km (371 miles). Larger wheels generally increase energy consumption and reduce range.
WLTP energy consumption is 15.1 kWh/100 km for the base configuration and 17.8 kWh/100 km for the highest-consumption configuration.
For more details about the range, see real-world data and range listings on this model’s range and consumption page.
The vehicle supports fast DC charging with a maximum power of 600 kW. A 0–100% charge takes approximately 35 minutes. A typical 10–80% session takes about 13 minutes at an average power of 348 kW.
With five minutes of overhead per stop, the optimal charging window is 0–62%. Effective average power, including overhead, is 283 kW over a session lasting about 14 minutes and 57 seconds.
The Mercedes GT 55 4-Door Coupé 4MATIC+ supports high-power DC charging.

The suspension is fully adaptive on the front and rear axle, so height and damping can be adjusted manually and automatically.

Regenerative Braking
Regenerative braking works in two ways: through one-pedal driving, or through the brake pedal using blended braking while coasting.
However, it is not considered full one-pedal driving since, at low speeds, the vehicle will keep rolling until it comes to a stop by itself.Drivers can also adjust the regenerative braking strength when lifting off the accelerator. There are four levels of regenerative braking to choose from, allowing you to customize the driving experience to your preference.
