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. It operates at a nominal voltage of 800 volts. The high voltage supports faster DC charging.
Under the WLTP (Worldwide Harmonized Light Vehicles Test Procedure) standard, the vehicle's range varies between 700 to 597 km (435-371 miles), depending on the specific configuration and options, such as wheel size. Larger wheels can increase energy consumption and subsequently reduce the overall range.
The vehicle's energy consumption is rated at 15.1 kWh/100 km for the base model and 17.8 kWh/100 km for the top-tier model under the WLTP test cycle.
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. Charging from 0% to 100% takes approximately 35 minutes, while a typical 10% to 80% charge takes about 13 minutes with an average charging speed of 348 kW.
Considering an additional 5 minutes for each charging stop due to driving interruptions, the optimal charging range is from 0% to 62%. This results in an effective charging speed, including time lost, of 283 kW, with each charging session taking about 14 minutes and 57 seconds.
This places the Mercedes GT 55 4-Door Coupé 4MATIC+ among the fastest-charging EVs available.
Onboard Charger
The standard onboard charger supports up to 11 kW for Level 1 and Level 2 AC charging, allowing a full 0–100% charge in about 9 hours and 38 minutes with a standard home setup.
Charge Port
The location of the charge port is on the right rear corner. This placement makes it easy to use charging stations that require backing up to connect.
The connector types vary between different markets. This model uses NACS for North America and CCS Combo 2 for Europe. For complete specifications for all markets, refer to the full specifications.
