While 2025 may not be its heyday, the humble four-door non-SUV—known as the sedan, for those who need a refresher—is thankfully still present on America’s new car lots. Especially on Mercedes-Benzs’, which, between its CLA, C, E and S Classes, give buyers plenty of options to suit their lifestyle. And for the more discerning and well-heeled enthusiast, there’s yet another four-door MB model, but this one answers the question “what if you added two seats with accompanying doors to a sports car badge, and still made it look good?”
I’m not sure who would ask for this in a four-door. Not only that, I’m not sure who would also request that it be the most powerful Mercedes product ever made. Nonetheless, I’m glad the brand took the less conventional path and built it; starting at $200,100, the 2025 Mercedes-AMG GT63 S E Performance four-door gran coupe sports as much herculean performance and stature as this herculean price tag.

Somewhat Understated
The four-door GT63 really does look like a bigger and longer two-door GT63, too. Sure, the structure was dramatically changed to be a sedan – or, in Mercedes’ words, gran coupe – but it’s an overall handsome brute. I’m especially into the it’s rear three-quarter perspective as minimal overhang, a wide track and broad shoulders give it a particularly muscular appeal. It wears its game face, too, with massive vents to aid cooling, and its headlights are quite sharp. Finally, in classic understated German sedan fashion, there isn’t too much about its exterior that would alert casual observers (or law enforcement) of its capabilities.

However, Mercedes was on-the-nose in conveying them on the inside. A rich mix of Alcantara, soft leather, and carbon fiber comprise every surface, and standard substantially bolstered sport seats are quite comfortable. The belt line sits high to create a pleasingly sunken driving position that’s focused and assuring, which is rare among other sport sedans. Minor downside: with such a big footprint and slightly limiting visibility, this requires taking extra care navigating tight city streets and parking lots.
The whole idea behind expanding a two-door high-end sports car into a four-door is to tack on an extra row of seats, but in the AMG GT63, this seemed like an afterthought. $200,000 is a heavy piece of scratch, and I was surprised to see such a barren and claustrophobic rear seat area for it. The roofline curves down to give the GT its sleek and sporty figure, so it’s understandable that headroom’s at a premium. But still, it’s quite cramped, and has barely any common amenities like multiple USB-C ports, or even cupholders, for the base price.

Impressively Thrilling
Between its sporty looks and focused interior, the 2025 Mercedes-AMG GT63 S E-Performance’s intentions are clear. But there’s more: it’s capable of producing 831 horsepower and 1,032 pound-feet of torque. Just 630 and 664 are courtesy of its hand-assembled twin-turbo 4.0-liter V8 (just), and the rest of a product of its plug-in hybrid system, which is made up of an electric motor mounted to the rear axle, 6.1 kWh battery, 3.7 kW onboard charger, and 400v electric system. All of this enables the 5,200-pound GT to hit 60 mph from a standstill in just 2.8 seconds, and on to a top speed of 197 mph. Whether launching it or eclipsing triple-digit speeds, there’s plenty of rousing V8 drama and longitudinal G force to keep pulses high, and nine perfectly spaced gears within its dual-clutch transmission to ensure the least amount of interruption.

Despite its heft, this stretched-out sports car is a maniac at corners, too. Because its 76.9-inch width is spread across a vast 116-inch wheelbase, there’s plenty of room for its mighty four-liter and accompanying accessories to sit quite far back under the hood. This makes it easier to balance its handling equation, as do adaptive dampers with airbags living amongst multi-link suspension at all four corners, plus rear-steer, and all-wheel drive to put the power down more effectively.
Tackling mountain roads was a real treat in this AMG; steering response and weight were solid, and while too stiff in its most hardcore setting, damping made the experience wonderfully engaging and confidence-inspiring. Well, in addition to its massive 275-front and 315-rear Michelin Pilot Sport Cup 2 tires, as well as gigantic 16.5-inch front and 15-inch rear carbon ceramic brakes with massive, multi-piston calipers. Ambient temps hovered around 90 degrees during my afternoon behind the wheel, and besides some brake and tire fade after nearly an hour of play, the GT’s oil and coolant temperatures remained pegged in the middle the whole time. Previously, I’d driven the new/similarly hefty BMW M5 on the same roads, and vastly preferred the AMG for its livelier soundtrack, better ride quality and more engaging steering. It costs quite a bit more than the Bimmer and they aren’t technically direct competitors, but it’s a context clue for how each luxury brand deals with weight in our modern plug-in hybrid performance era.

At the end of the day, the AMG GT63 is a luxury sedan, and it’s just as good at wearing this hat as it is at playing race car. The ride in either Sport or Comfort mode is excellently damped and composed, and there’s nary a squeak or rattle in its interior as it rolls down city streets. If someone simply wanted a roomy, isolated luxury boat with enough power on tap to keep up with modern supercars, they could do far worse.
This is driven home by the GT63’s hybridized powertrain—that’s right, we can’t forget there’s environmentally friendliness factored into this bruiser. When driven with an eye on consumption, it’ll return a combined 25 mpge. Though, it’s not quite as good at split-personality motoring as the latest BMW M5; electric-only range is just one mile. Enough to be respectful of other peoples’ peace in town, but not much in terms of regular, emissions-free motoring. But since it already weighs as much as a well-optioned Ram 1500, it really ought to not gain any more pounds.

Despite having a very base backseat at $200,100 to start, the 2025 Mercedes-AMG GT63 S E-Performance is as handsome, fast, engaging and fun as it is luxurious. At least in its front seat area. The idea of simply stretching out a coupe’s design to slot in a big four-door grand tourer—in a lineup already laden with four-doors—seems like too much, but Mercedes pulled it off well here. It’s a testament to the tech, too, as just five years ago it would’ve been unheard of to make 5,200 lbs drive this well.
