The Mercedes-AMG GT63 Coupe enters its 2nd generation and it has taken a bit of a different direction from the previous iteration. It’s now bigger, heavier, but more usable in more situations. Does this mean that Mercedes-Benz have neutered the AMG GT or is it still a wild animal?
Performance
Engine – Under the hood is a very familiar 4.0L bi-turbo V8 that is found in almost all 63 series (except the C63) of AMG models. In this AMG GT63, it produces 577 hp and 590 lb-ft of torque (430 kW & 800 Nm). Though those power figures are less than some other AMG models, the 2025 GT63 can still accelerate from 0-100 km/h in 3.2 seconds, according to Mercedes-Benz. In the real world however, this car is a bit faster as I found out with a time of 3.13 seconds. The AMG GT63 Coupe has a few different telemetry pages, one of which is a Drag mode that measures drag times as well as 0-100 km/h times. 3.13 seconds was the best I was able to manage under ideal conditions with the Race start mode activated. In less than ideal conditions, such as rain, the car completely abandons the race start mode. Nevertheless, this car’s acceleration is ferocious when it can get the power to the ground.
The engine does not use any sort of mild-hybrid technology. The turbochargers are positioned in a “hot V” configuration for improved response but some turbo lag is still evident and this engine has a high boost threshold. Peak torque is not reached until 2,500 rpms which is higher than some other high performance V8 engines like the one in the BMW M5. below or around those rpms, the car doesn’t accelerate very quickly. Once the turbochargers provide full boost, you’re getting pushed into the back of the seat. At times, this AMG GT63 Coupe can feel like an old-school turbocharged car because of its unique power delivery. On top of that, the engine makes some glorious V8 noises with burbles at idle, machine gun rattle at higher rpms, and bangs on downshifts. This engine provides a lot of drama to the driving experience of the Mercedes-AMG GT63 Coupe.
Fuel Economy – If you’re thinking of purchasing a vehicle such as this, fuel economy is probably not on your mind. It’s not very good. The GT63 Coupe is rated for 19.7 L/100km (11.9 MPG) in a city and 12.6 L/100km (18.6 MPG) on a highway. I managed to average 17.8 L/100km (13.2 MPG) during my time with the car.
Transmission – Paired with the ferocious engine is a 9-speed multiclutch transmission. In city driving, it smoothly upshifts to the next gear without you feeling the shift. For the most part, it’s smooth to change down as well but at times you do feel a slightly harsher downshift.
In the Sport+ and Race drive modes, the gear changes are as ferocious as the engine. Each upshift and downshift feels as though someone is kicking the back of your seat on an airplane. But at least the transmission reacts quickly to driver inputs in these modes.
Braking – As standard, the AMG GT63 Coupe has 6-piston fixed calipers and 390 mm discs on the front that provide the bulk of the stopping force. This demo vehicle that I drove had the optional carbon ceramic brake discs which are 10 mm larger and have a two-piece design. Carbon ceramic discs are lighter than steel discs and are virtually fade resistant. In everyday driving, it’s almost impossible to overheat these discs, unless you drive like an idiot, so they provided smooth and power stopping power every time I put my right foot on the brake pedal. Paired with the very wide, sticky summer performance tires, the AMG GT63 Coupe stops on a dime despite its heftier weight over the previous generation.
Handling – This 2nd generation AMG GT63 Coupe tips the scales at 1,970 kg (4,343 lbs), a gain of almost 250 kg over the previous generation. This weight gain is due to increased safety, body rigidity, and convenience features. But most of it is due to the standard 4Matic+ AWD system. This system allows the engine’s power to be shuffled between the front or rear wheels and, being the more advanced + version, it can decouple the front wheels and allow the AMG GT to drift. Additionally, the GT63 Coupe is equipped with standard rear-wheel steering with up to 2.5 degrees of steering angle. There’s also a nose lift system that can raise the front axle by 30 mm. This system can remember points at which it is activated and then automatically raise the nose when the car is at that same GPS position again.
As for the driving dynamics of this GT63 Coupe, it is responsive and grippy. Despite the heavier weight, the front end immediately responds to the smallest turn of the steering wheel. Coupled with the 295 wide front tires and 305 wide rear tires, the car has more lateral grip than you can use on public roads. At no point did the car feel as though it wanted to snap oversteer or understeer when entering a corner on a windy road. To fully appreciate the performance of this car, you’d have to go to a race track.
Comfort
Ride Comfort – Being a high performance sports car, the ride of the AMG GT63 is firm on city streets. However, the adaptive suspension in Comfort mode provides just enough isolation from the road. What is very evident are sharp and quick bumps. The low profile tires make small bumps feel bigger than they actually are.
This demo vehicle came equipped with the optional performance AMG seats. These provide a lot of lateral support when driving enthusiastically on your favourite roads. But they have firm padding when you’re travelling on city streets. As a result, my butt felt numb after half an hour of driving. If you don’t plan to do many trackdays with this car, stick to the standard seats.
Interior Space – For the first time, the AMG GT Coupe is available in a 2+2 configuration. Its larger size means that it comes standard with rear seats but they can be removed if you don’t have a need for them. This demo car had the latter option which provided a very useful parcel shelf.
As for the front occupant area, it is very spacious with plenty of legroom and headroom for taller individuals like me at 6’4”. Visibility out of the car is good too with very small blind zones and a big enough rear window.
In the trunk, the 2025 Mercedes-AMG GT63 Coupe has 351 L of cargo space. Under the trunk floor, you’ll find a tire repair kit.
Noise, Vibration, & Harshness – As I mentioned earlier, the AMG GT63 Coupe makes some great engine noises that can be heard in the cabin. But when you don’t have your right foot to the floor, the cabin of this sports car is flooded with tire noise. The volume of this unwanted noise really depends on the type of asphalt the car is driven on. If it’s fresh, there’s very little tire noise. If it’s old and porous, it’s very loud.
Additionally, I did notice some rattles as the car drove over bumps. These rattles came from the trunk area but I couldn’t tell if it was the trunk cover or the divider between the cargo area and the passenger area.
Odds and Ends
Pricing – The 2025 Mercedes-AMG GT is an expensive car. Here in Canada, it’s only available in two trims; the GT55 and the GT63. The GT55 starts at $157,900 CAD ($138,150 USD) while the GT63 starts at $198,300 CAD ($181,350 USD). In the United States, there are 5 trims to choose from including the GT43, GT63 Pro, and the GT63 S E-Performance. No word if Canada will be getting these models.
Gadgets – The AMG GT63 comes equipped like almost all other AMG models. It has Nappa leather upholstery, a microfiber headliner, heated & ventilated seats, a heated steering wheel, dual-zone automatic climate control, a wireless phone charging pad, a head up display, surround view cameras, Burmester surround sound system, panoramic sunroof (but it’s fixed and cannot open), 64-colour ambient lighting, and a power operated trunk, among a few other convenience features.
But being an AMG model, it also comes equipped with a few features that help the driver when the car is on a race track or customizing different settings. The AMG drive unit consists of two knobs on the steering wheel. The right one cycles through the different drive modes. The left one can adjust various parameters of the car. These parameters can be added or removed to this drive unit via the infotainment screen. The car also comes with the AMG Track Pace app. This allows the driver to keep track of lap times, quarter mile times, braking distances, and various telemetry data.
As for the infotainment system, the GT63 has the latest iteration of MBUX. It functions the same way as it does in all newer Mercedes-Benz vehicles and it allows for some controls to be performed by voice rather than needing to use the touchscreen.
Interior Design – The AMG GT Coupe used to have a unique interior design. It still felt like a Mercedes-Benz vehicle but it was unlike any other model in the lineup. Sadly, that is no longer the case with this 2nd generation. It has the same 11.9” touchscreen for the infotainment system, the same 12.3” screen for the driver instrumentation, the same AMG steering wheel, and the same seat controls as all other Mercedes-Benz vehicles. Not only does it lose physical controls for commonly used functions, but it also lost the fighter jet looking row of buttons on the center console. The interior just doesn’t have a feeling of craftsmanship anymore.
Having said that, the materials are great. There’s leather covering almost every panel in the cabin, including those that are lower down. There’s also real carbon fiber across the center console and subtle touches of real aluminum. But the cover for the cup holders and wireless charging pad is covered in gloss black plastic which will attract smudges and scratches.
Exterior Design – The new AMG GT is bigger but the proportions still look great. It has a long hood with power bulges, short overhangs, a wide stance, and rear fenders that are reminiscent of a Porsche 911 when you look out of the exterior mirrors. There’s also a rear spoiler that deploys automatically at about 80 km/h or it can be manually raised via the AMG drive unit. Additionally, the optional 21-inch matte black wheels are the proper wheels to option your AMG GT.
Safety – The 2025 AMG GT63 comes equipped with a lot of basic safety & driver aids such as automatic emergency braking, blind spot sensors, lane departure warning, and adaptive high beam assist to name a few. It has an available Driver Assistance Package which adds more advanced versions of the standard safety systems such as evasive steering assist, active lane change assist, and route-based speed adaptation among many others.
Warranty – Just like every other Mercedes-Benz vehicle, the 2025 AMG GT63 comes with a 4 year / 80,000 km new vehicle warranty. It also comes with 4 years / unlimited km roadside assistance, 4 year / 80,000 km surface corrosion, and 8 year / 130,000 km warranty for certain emission parts.

Conclusion – Overall, the new AMG GT Coupe is a better day-to-day sports car than the previous generation. But it can still get your heart pumping with its ferocious acceleration and cat-like grip. Perhaps on a race track, the heavier weight will hamper it against the Porsche 911 but most of the time, cars like these are spending their days on city streets rather than race tracks.
