Mercedes-Benz AMG continues to expand its redesigned GT Coupe lineupthis time with the addition of the first plug-in hybrid version.
The 2025 Mercedes-Benz AMG GT 63 SE Performance arrives in U.S. dealerships later this year as the most powerful version of the GT Coupe, boasting a maximum output of 805 hp and 1,047 lb-ft of torque from its sophisticated plug-hybrid powertrain. in.
That powertrain consists of a 4.0-liter twin-turbo V-8 up front that produces 603 hp and 627 lb-ft of torque on its own, driving all four wheels through a 9-speed automatic transmission. An electric motor in the back can send up to 201 hp and 236 lb-ft of torque to the rear axle through its own 2-speed gearbox.
Mercedes quotes a 0-60 mph time of 2.7 seconds, making the GT 63 SE Performance the fastest “series production” AMG model to date, according to the automaker. Top speed is estimated at 199 mph.

A 6.1 kWh battery mounted above the rear axle utilizes lessons learned from F1, which has helped increase energy density and enables faster energy consumption. A direct cooling system for the pack’s 560 cylindrical cells also helps remove excess heat more quickly. Mercedes doesn’t have an EPA range estimate for electric power alone. The automaker also did not provide a charging time.
Four levels of braking energy regeneration are available, capable of feeding up to 100 kW back to the battery, Mercedes claims. Normal friction braking is handled by carbon-ceramic rotors with six-piston calipers at the front and single-piston calipers at the rear.
Rear-wheel steering and AMG Active Ride Control active roll stabilization are standard. The latter hydraulically interconnects the four wheels, allowing greater comfort when locating impacts from bumps or other imperfections, while also neutralizing body movement in its sportier settings.

A retractable rear spoiler automatically adjusts to one of five different angles (above 80 km/h) depending on the driving mode. The car can also lower 1.6 inches at speeds above 50 mph, triggering an active aerodynamic element in the underbody that helps reduce front axle lift. The standard aerodynamically optimized 20-inch wheels are wrapped in size 295/35 tires at the front and size 305/35 tires at the rear (21-inch wheels are also available).
Pricing will be revealed closer to the E Performance’s arrival in dealerships, but this plug-in hybrid is expected to sit at the top of the AMG CT Coupe lineup. This line already includes the GT 55 and GT63 variants released for the 2024 model year, as well as the AMG GT43 also launching for 2025.
Another version, should be called GT 63 S and located between the GT 63 and the GT 63 SE Performance, it could arrive as a 2026 model.
