Last year I spent some time with the GT63 S E Performance, the hybrid-assisted iteration of Mercedes-AMG’s most focused two-door road car. While I came away impressed by its straight-line speed, its weight and complexity ultimately demanded significant compromises in terms of both dynamics and usability. Given those shortcomings, it should come as little surprise that the announcement of the GT63 Pro immediately piqued my interest.
The 2026 Mercedes-AMG GT63 Pro carries a starting price of $202,200, a figure that happens to be identical to the base MSRP of the 2026 GT63 S E Performance. Employing a strategy that seems cribbed directly from Porsche’s playbook, the Pro’s premium price tag is largely associated with what’s been shed rather than gained.

At an official curb weight of 4,299 pounds, the GT63 Pro is more than 500 pounds lighter than the GT63 S E Performance, and that’s due in large part to the absence of the latter’s hybrid system. And while the E Performance is designed to be a fast grand tourer that can go toe-to-toe with the 911 Turbo S and Aston Martin DB12, the Pro employs a focused intent as a track-capable sports car, in turn putting benchmark machines like the 911 GT3 in its sights.
It’s an interesting proposition given the second-generation GT’s switch to an SL-based architecture, its newfound 2 + 2 seating layout, and its standard all-wheel drive configuration. But when a press car shows up on a set of ultra-sticky Michelin Pilot Sport Cup 2 R tires, it’s a strong indicator that the automaker has some lofty dynamic ambitions for the model.

At nearly 4,300 pounds, the GT63 Pro is still a bit of a porker for a track-focused sports car. That figure makes this car more than half a ton heavier than a 911 GT3 (and about 600 pounds heavier than the first-generation Mercedes-AMG GT R), but it makes up for the mass in other ways.
In terms of its design philosophy, the GT63 Pro isn’t as stripped down and purpose-driven as a 911 GT3. Sure, massive carbon-ceramic brakes, enhanced cooling for the powertrain and brake system, and more aggressive aero are all standard equipment here, but so are a Burmester surround-sound audio system, ventilated front seats, and the same amount of sound deadening as you’d find in a standard GT63. Mercedes-AMG clearly wasn’t willing to ditch the GT’s more luxurious characteristics for the sake of lap time supremacy. Instead, it employs one of AMG’s classic calling cards: brute force.
Even though the 4.0-liter twin-turbo V8’s output figures of 603 horsepower and 627 pound-feet of torque here in the GT63 Pro are a far cry from the jaw-dropping numbers that the GT63 S E Performance puts out, these figures still comprehensively outgun the GT3’s naturally aspirated flat-six and represent gains of 26 hp and 37 lb-ft over the standard GT63. Matched with a nine-speed multi-clutch automatic gearbox and a fully variable all-wheel drive system, AMG says the GT63 Pro will hit 60 mph in 3.1 seconds on its way to a 10.9-second quarter-mile time and a top speed of 197 mph.
The GT63 Pro also uses the same suspension setup as the standard GT63, a configuration which ditches traditional mechanical anti-roll bars in favor of hydraulic actuators that work in tandem with adaptive dampers to counteract body roll in the corners while also keeping ride quality in check.
Although the suspension tuning is still pretty firm even in its softest setting, it’s worth noting that the GT63 Pro delivered more compliance on the pockmarked streets of Los Angeles than the PASM Sport Suspension-equipped 992.2 911 Carrera S that I’d driven the week prior. Combined with its relatively spacious cabin and the sport seats’ wide range of adjustability, the GT63 Pro can dispatch the daily commute as well as long-haul touring stints in genuine comfort. And without the E Performance’s hybrid system in the mix, the V8’s baritone roar takes center stage from the moment you press the ignition button, while the absence of that model’s rear-mounted battery pack also frees up a substantial amount of cargo space.
The GT63 Pro’s simplified approach also pays dividends out in the canyons. In my review of the E Performance, I noted that the brake system’s response was alarmingly inconsistent, but those issues have been completely rectified here, while the massive amount of mechanical grip afforded by those Michelins (along with the lower curb weight) translated to noticeably improved stopping power in general. This, combined with the car’s newfound agility and eagerness to change direction, translated to a lot more confidence behind the wheel when exploring the Pro’s dynamic limits.
While the 911 GT3 may be the GT63 Pro’s primary rival, the AMG offers a very different driving experience. Whereas the GT3 encourages you to wind its flat-six to the moon, the Pro’s boosted V8 does its best work in the mid-range, where the AMG has a massive advantage in torque. There’s also something to be said for the additional reassurance that the all-wheel drive system affords, especially when you’re about to mash the loud pedal coming out of a slow corner.
But there are still situations where it seems like Mercedes-AMG’s engineering gets in its own way. While the gearbox delivers quick shifts, its constant hunt for a better cog in the Race drive mode quickly convinced me to take over shifting duties with the paddles. And that also brings me to another point of contention: the convoluted control layout.

Setting aside the annoyance that almost all of the car’s features are adjusted with either capacitive surfaces or on the 11.9-inch touchscreen center display (as well as the fact that the seats’ lumbar and bolster settings are buried in an infotainment menu while the rest of the seat adjustments are on the doors), the only way to quickly access the vehicle’s myriad of performance settings is with the “AMG Drive Unit,” a pair of customizable toggles on the lower left-hand side of the steering wheel. Because this module can only display two different settings at a time, you’re forced to prioritize having immediate access to manual shift mode for the transmission, or the loudness settings for the exhaust system, or damper stiffness settings, or traction and stability control settings, and so on.
I mention this because during my initial stint out in the canyons, I noticed a behavior that seemed almost like a brake-based torque vectoring system quickly applying and releasing the front brakes multiple times when taking a fast corner on maintenance throttle. Well below the threshold of grip afforded by these track-ready tires, I initially theorized it had something to do with the all-wheel drive system, so I enabled Drift Mode – which disconnects the front axle from the rest of the drivetrain – and the issue went away. (And yes, the GT63 Pro will indeed do gloriously smoky drifts if you ask it to.) To verify that the issue was indeed the all-wheel drive system, I then disabled Drift Mode. I expected that weird behavior to come back, but confusingly, it didn’t.

What I eventually discovered was that, despite the fact that this behavior was happening while the tires still had plenty of grip, it appears that the stability control system’s overactive default setting was basically intervening preemptively. The stability control system has to be fully disabled to fire up Drift Mode, which required me to bring up the traction and stability control setting on that AMG Drive Unit control module in order to quickly turn it on or off.
Even with the stability control system only partially disabled in its Sport setting, that mid-corner braking issue didn’t return – it only came back when system was fully enabled again. And that seems to indicate that if you’re going to drive this car in any sort of spirited way on a winding road, you’ll probably want to have quick access to that stability control setting, which means that the setting will either need to be a permanent fixture on the AMG Drive Unit, or you’ll have to pull off to the side of the road and bring it to the fore every time you want to have some fun. Given how labyrinthine the menus and control setups are in this car, I could absolutely envision a situation where someone would not make this discovery, simply assume this was normal behavior for the GT63 Pro, and end up just living with that issue for the duration of their ownership.
That’s a bit of a bummer because this is otherwise a lovely beast of a sports car. It may not be as focused as a 911 GT3, but it’s far more accommodating on a day-to-day basis, and it delivers a distinctive driving experience that nails the AMG hallmarks.
Given the choice, I’d take the GT63 Pro over the more powerful GT63 S E Performance without hesitation. At this point, it seems like the only thing holding this car back from true greatness is AMG’s recent tendency to go overboard with the engineering. The GT63 Pro is proof that less can indeed be more, and I suspect that there’s still something to be gained by taking that philosophy a step further.
