2025 Mercedes-AMG GT63 Plug-In Hybrid Is an 805-HP Beast

Mercedes revised the aerodynamics for the AMG GT63 S E Performance, adding a new carbon element on the underbody ahead of the engine. This piece lowers by roughly 1.6 inches when the car reaches 50 mph, creating a Venturi effect that pulls the car downward and lessens lift on the front end. The E Performance is also fitted with a retractable rear spoiler that raises at over 50 mph and can alternate among five different angles either to improve stability or minimize drag.

The E Performance comes standard with AMG’s active ride control, which uses active hydraulics instead of mechanical anti-roll bars that work in conjunction with adaptive dampers—each featuring two hydraulic connections—that are all interconnected. Mercedes says this system allows for “a very wide roll spring rate while at the same time reduce rolling movements,” so the AMG can easily switch between comfortable daily driving and athletic handling. Rear-wheel steering is also standard, making the sports car more stable under high-speed corning and more nimble in tight spaces.

Visual changes are minor, with a charging port at the rear, a red “GT 63 S” badge, twin trapezoidal tailpipes, and “E Performance” badges on the front fenders. 10-spoke, 20-inch wheels finished in Tantalum Grey are standard, with other 20- and 21-inch designs available. Behind the wheels sit bronze six-piston fixed front calipers and single-piston floating rear calipers. These clamp onto carbon-ceramic brake discs that measure 16.5 inches up front and 15.0 inches at the rear.
