EV Channels Review
The 2025 Mercedes-AMG GT 63 S E Performance is put to the test in a "Coffee Run Challenge" to assess its real-world electric range, which the EPA rates at a mere one mile. The reviewer found the car's electric system to be surprisingly capable, easily exceeding the EPA rating. While the car's battery capacity is small (4.8 kWh usable), the powerful 150 kW rear electric motor allows for brisk acceleration in electric mode, comparable to full EVs. A key positive is Mercedes' implementation of the accelerator pedal, which reserves a portion of travel for electric power before engaging the combustion engine, preventing harsh cold starts. The reviewer praised the car's ability to achieve over 9 miles of electric range in mixed urban driving, a significant improvement over the EPA estimate. However, the reviewer noted the car's limited usable battery buffer, with a significant portion reserved for performance, and expressed a desire for more user control over battery depletion. Despite the small electric range, the reviewer concluded that for short urban commutes, the electric capability is useful for avoiding cold starts and emissions from the V8 engine, making it a viable performance hybrid.
