The 2027 Mercedes-AMG GT 55 4-Door Coupe pairs a tri-motor powertrain with luxury features and digital theatrics to create what Mercedes positions as an engaging electric performance car for enthusiasts.
The GT 55 uses three axial-flux motors engineered with YASA to produce 805 hp peak power and 1,372 pound-feet of torque, with a continuous rating of 557 hp. Mercedes claims a 2.7-second 0–60-mph time and 186-mph top speed with the AMG Performance package. Two rear motors and one front motor drive the layout. The optional hydraulically interconnected damper system paired with multilink suspension, forged aluminum components, and up to six degrees of rear-axle steering delivers responsive handling without excessive harshness. On tight mountain roads, the 5,501-pound curb weight and Continental SportContact 7 tires occasionally struggled to match the chassis confidence on steep downhill slaloms, though optional carbon-ceramic brakes proved durable.
The car mimics an internal-combustion experience through AMGForce Sport+, which simulates V-8 engine sounds, transmission behavior, engine braking, seat vibrations, and gear changes based on the previous-generation AMG GT R Coupe. The 106-kWh battery pack charges at speeds exceeding 600 kW, reaching 10 to 80 percent in 11 minutes at maximum. Mercedes claims up to 434 miles of WLTP range, suggesting EPA estimates above 300 miles. The system switches between 800 and 400 volts for more flexible charging compatibility.
The four-door hatchback seats adults comfortably in back and offers 14.7 cubic feet of cargo space plus a carbon-fiber frunk. The interior uses quilted leather on doors and includes a dedicated tachometer in Sport+ mode, though seat heating and ventilation controls require multiple touchscreen inputs and drive mode menus demand patience to navigate.
The GT 55 starts at $146,500, roughly $30,000 below the GT 63 at $176,550. Compared to the Porsche Taycan 4S and GTS variants, the AMG proves quicker in straight-line acceleration while offering more rear passenger and cargo space.
