2025 Mercedes-AMG GT 63 S E Performance is a wicked-fast PHEV

There’s a new top dog in the Mercedes-AMG GT Coupe lineup. Say hello to the 2025 Mercedes-AMG GT 63 S E Performance. As the “E Performance” bit of its name suggests, it adds hybrid power to Mercedes’ most-focused series AMG car. Specifically, it turns the AMG GT into a plug-in hybrid with a tiny battery pack and high-power electric motor.

How much power? Try a combined 805 horsepower and 1,047 pound-feet of torque from its 4.0-liter twin-turbo V8 and the electric motor. That gives it an edge over the next-most powerful AMG GT 63 by 228 ponies and a thumping 457 lb-ft. Of course, it’s the quickest version to 60 mph, putting in a time of 2.7 seconds, and its top speed is 1 mph shy of the 200 mark. The electric motor shifted by a two-speed transmission is mounted on the rear axle and peaks at 201 horsepower for bursts of acceleration but can provide a continuous output of 94 horsepower. The 400-volt, 6.1-kilowatt-hour battery pack with a unique Formula 1-derived cooling system is also in the rear for weight distribution purposes.

Just like the other versions of the AMG GT, this one offers 4Matic all-wheel drive, even when being run on electric power. Mercedes doesn’t quote an electric range estimate, but considering the AMG GT 63 S E Performance 4-Door Coupe with its version of this powertrain can only manage 7 miles, we suspect this one will cover a similar amount of ground. It’ll be most useful in European cities with low-emissions zones, but much less so here in the U.S. The battery can be charged up by plugging into the port on the rear bumper. Energy recuperation via regenerative braking has four(!) settings and can be strong enough that Mercedes says it can be driven like an EV with a one-pedal drive mode.
