2025 Mercedes-Benz AMG GT 63 S E-Performance Unveiled

Arriving later this year at U.S. dealerships, the 2025 Mercedes-Benz AMG GT 63 S E Performance emerges as the apex of the GT Coupe series, harnessing a formidable plug-in hybrid powertrain to deliver an astounding 805 horsepower and 1,047 lb-ft of torque.

Powering the vehicle is a combination of a front-mounted twin-turbocharged 4.0-liter V-8 engine generating 603 horsepower and 627 lb-ft of torque, connected to all four wheels via a 9-speed automatic transmission. Adding to this prowess is an electric motor situated at the rear, capable of supplying up to 201 horsepower and 236 lb-ft of torque to the rear axle through its dedicated 2-speed gearbox.

Mercedes-Benz boasts a rapid acceleration, with a claimed 0-60 mph time of 2.7 seconds, positioning the GT 63 S E Performance as the fastest "series production" AMG model in the brand's history. The vehicle's top speed is reported at an impressive 199 mph.

Employing insights gleaned from Formula 1, Mercedes-Benz integrates a 6.1-kWh battery pack positioned above the rear axle, boasting enhanced energy density and expedited energy retrieval capabilities. The battery pack's 560 cylindrical cells benefit from a direct cooling system, facilitating efficient heat dissipation. Mercedes refrains from providing an EPA range estimate for electric propulsion alone and remains mum on charging durations.

The vehicle offers four levels of brake-energy regeneration, capable of channeling up to 100 kW back into the battery pack, as per Mercedes' assertions. Braking duties are primarily handled by carbon-ceramic rotors featuring six-piston calipers at the front and single-piston calipers at the rear.

Standard features include rear-wheel steering and AMG Active Ride Control, which employs hydraulic interconnections among the four wheels. This system enhances comfort by localizing impacts from road irregularities and counters body roll in more spirited driving modes.

At speeds surpassing 50 mph, a retractable rear spoiler seamlessly adapts to one of five preset angles, contingent upon the selected drive mode. Additionally, the vehicle has the capability to lower itself by 1.6 inches when exceeding 50 mph, activating an underbody active aerodynamic feature aimed at mitigating front axle lift. Standard 20-inch wheels, optimized for aerodynamics, sport 295/35-size tires at the front and 305/35-size tires at the rear, with 21-inch alternatives also on offer.

While pricing details are pending closer to the arrival of the E Performance model at dealerships, it is anticipated that this plug-in hybrid will command the top tier of the AMG GT Coupe range. This range currently encompasses the GT 55 and GT 63 variants introduced for the 2024 model year, along with the forthcoming AMG GT 43 slated for 2025.

An additional iteration, potentially dubbed the GT 63 S and positioned between the GT 63 and the GT 63 S E Performance, is projected to debut as a 2026 model.
