Hey Guys, Checkout the all-new plug-in hybrid new 2025 Mercedes-AMG GT 63 S - E Performance. Mercedes's new 805-hp plug-in-hybrid hatchback focuses on speed over efficiency.
The GT63 S E Performance's extra mass is brought on by electrifying the powertrain. Just like the pure-gasser GT63, under the hood lies a twin-turbocharged 4.0-liter V-8; here, the eight-pot is tuned to 603 horsepower and 627 pound-feet of torque and pairs to the brand's nine-speed automatic with a wet clutch in place of the traditional torque converter.
At the rear axle is an electric drive unit that consists of a motor with 201 horses and 236 pound-feet, a two-speed transmission, an electronically controlled limited-slip differential, an inverter, and a 4.8-kWh liquid-cooled lithium-ion battery pack. Besides a few mounting points, this arrangement is identical to the hardware found at the back of the C63 S E Performance. Mercedes claims the e-unit adds nearly 500 pounds to the already porky platform.
By our math, that places the GT63 S E Performance right around 4800 pounds. Staggering. But what's more astounding is the powertrain's combined outputs of 805 horsepower and 1047 pound-feet, routed to all four wheels.
The electric motor puts out full thrust in 10-second doses before tapering off to deliver 94 horses in 60-second intervals. The acceleration is teeth-clenchingly relentless all the way to 190 mph. We have no doubt in this car's ability to slam into its governed top speed of 199 mph. In fact, it feels like the car has an easy 220 mph in the bag, but engineering the rotating bits to work beyond 200 mph is a costly endeavor. Mercedes claims 60 mph arrives in 2.7 seconds with Race Start activated. The seats' stitching patterns embedded in our back suggest something much quicker, maybe even a top-10 spot on our acceleration leaderboard.
Naturally, a heavy car capable of such intense velocities needs a big brake package, and the E Performance delivers the goods. Monster 16.5-inch carbon-ceramic rotors pinched by six-piston calipers live within the front wheels, while 15.0-inch units and an off-putting single-piston caliper reside out back. We can safely say that this system comes in handy when a clapped-out Opel decides it needs the autobahn's left lane. We can also safely say that no one will enjoy the brake pedal's varying pressure. Sometimes you push on it and it's nice and firm, other times there's travel to it. It'll even move around underfoot during sustained pressure. It's an extremely odd pedal strategy that no one in the world ever asked for.
The GT63 S E Performance's lavish and technology-rich interior offers plenty of space for its front passengers, and while the back seat is optional, we'd call it mandatory. There's only enough headroom in back for small children, but the rear seat is the only way to get the folding divider that unlocks more cargo space. And that's critical in the E Performance, as the electric drive unit's load-floor bulge eats up five cubic feet compared to the nonhybrid GT63.
Yes, the GT63 S E Performance is a heavy car, but that's just the way she goes these days. If horsepower—aided by the roar of a gas-fed V-8—can keep pace with weight gains, so be it. Just make sure there's plenty of bite, which is definitely the case here. We expect pricing for this ultimate grand tourer to start in the neighborhood of $200,000 when it arrives later this year.
