Mercedes-AMG GT 63 Coupe 2025 Review

If you’re after AMG’s latest and greatest, you’ll need deep pockets. The 2025 Mercedes-AMG GT 63 officially starts at $370,400 plus on-road costs... but that’s just the beginning.

Tick a few option boxes like our test car – such as carbon ceramic brakes for an extra $13,000, a blacked-out AMG Night Package for $10,000 and grippy AMG Performance seats for $2,600 – and you’re staring down a total price of $403,300 before you even hit the road.

Factor in on-road costs you could easily get a Porsche 911 GTS ($400,200) for a similar price, a vehicle widely referred to as the everyday supercar.

However, bear in mind the 2025 Porsche 911 GTS isn’t as rapid around the famed Nürburgring Nordschleife as the new AMG GT 63 – 7:16.9 for the porker, while AMG reps reckon the GT 63 will do 7:11s… which is convenient if you're running out of fuel and need to grab a Slurpee mid-lap.

AMG spokesman Jochen Übler says the latest offering can record regular 7:11 laps around the Nürburgring Nordschleife, which isn’t too far adrift of the 7:04.632 lap posted by hotshoe race driver Maro Engel in the previous-gen GT R Pro.

It’s not just the price of admission that stings. Insurance and tyre bills on this 430kW twin-turbo V8 monster won’t exactly be small change either.

On the bright side, Mercedes-AMG backs the GT 63 with a five-year/unlimited kilometre warranty so at least you’re covered if anything goes pear-shaped.

There are also pre-paid service plans available to help soften the maintenance blow – though with tech like hydraulic suspension and rear-wheel steering, servicing costs are likely to be a lot higher than that of a Toyota RAV4.

The star of the show here is undoubtedly the 4.0-litre twin-turbo V8. Although its exhaust has been muzzled slightly due to EU regulations, the 430kW (576hp) eight-cylinder instrument emits a beautifully sonorous burble when idling. Hit the loud pedal and it becomes more insistent and as the revs rise the V8 symphony comes into its own.

It’s bassy, soulful and punctuated with authentic crackles on the overrun (although not as excessively as the previous generation). But I like that the odd pops and crackles aren't artificially generated; ease off the throttle after winding out two gears at full throttle, and excess fuel ignites in the exhaust system, punctuating the V8 warble and creating a very addictive soundtrack.

Unless you’re coming out of a Ford Mustang with a mandrel-bent titanium exhaust system, you won’t be disappointed with the acoustics.

Its 430kW and 800Nm of torque pumps through a responsive nine-speed multi-clutch transmission and the way the new 4MATIC+ all-wheel-drive system puts power to the ground is brutally effective. No slip, all grip.

The gearbox can take a beating too – launch control got a significant workout during the launch and drive and always felt robust and assertive.

The powertrain launches the 2025 AMG GT 63 from 0-100km/h in just 3.2 seconds on its way to a top speed of 315km/h. The launch control system is rather savage but utterly enjoyable, as you’re squeezed into the plush Nappa leather sports seats.

Ride and handling are good points too, and much improved over its predecessor. The AMG Active Ride Control suspension system replaces traditional anti-roll bars with hydraulics, effectively managing body roll while maintaining impressive ride comfort.

Even in Sport mode, the GT 63 remains liveable and comfortable enough for daily use.

Active rear-wheel steering makes urban driving and parking a little easier by reducing the turning circle, but also enhances agility in tight corners. Plus it provides stability in high-speed sweepers.

Mid-corner adjustments don't upset the car's balance either and it tracks through bends with almost surgical precision. The front-end hooks in confidently and there's tremendous grip throughout the corner.

For those who prefer the traditional rear-wheel-drive AMG experience, a drift mode of sorts sends 100 per cent of the power to the rear axle.

The brakes are also excellent – and they’d want to be when they cost an extra $13,000. But if you’re planning track days, they’ll be worth the extra clams.

Another boon for the second-gen AMG GT 63 is that it’s larger in every dimension. It’s 46mm longer, 177mm wider and with a 70mm longer wheelbase than before, resulting in a more spacious cabin. And for the first time, the AMG GT offers rear seats – but like the Porsche 911 they're super cramped… And there’s no two-seat option in Australia at present.

However, fold those rear seats down and you get an impressive 675 litres of cargo space – approaching SUV territory.

The cabin is also rather spiffy, blending luxury and sportiness with impressive finishes throughout. The digital cockpit features AMG's hyper analogue instrument display with multiple modes, including a track-specific view.

Standard equipment includes heated and ventilated sports seats with massage function, a Burmester 600W sound system and digital headlights that can project directional arrows onto the road to guide you back into your lane.

As alluring as the 2025 Mercedes-AMG GT 63 is, it’s not perfect, starting with that hefty price tag.

At over $400,000 before on-road costs, it’s rubbing shoulders with some seriously tough competition. Cars like the Porsche 911 GTS and Aston Martin V8 Vantage both deliver similar thrills for similar money.

They’re lighter and one could argue they’re a bit sharper and more focused on outright driving purity, certainly in the case of the Porsche.

Which brings us to the GT 63’s biggest challenge – its weight. At just over 1900kg tare, it’s a heavy car. AMG’s clever Active Ride Control suspension (which replaces traditional anti-roll bars with hydraulics) does an incredible job hiding that bulk in corners, but physics is physics.

In tight, technical sections, you feel that mass working against you, even if the grip and composure are remarkable. If I were to nit-pick, I’d also have to point out there’s some road and wind noise at higher speeds, not to mention its alarming appetite for high-octane fuel.

The official fuel economy claim is 14.1L/100km but our launch drive saw that figure edge closer to 18L/100km.

The steering is precise but it’s not bursting with feedback. Blame that partly on the sheer amount of electronic wizardry happening between your hands and the tyres. It’s always planted and confidence-inspiring but doesn’t have the driver to car connection a Porsche 911 delivers.

The 2025 AMG GT 63 is everything you want in a modern AMG flagship – savagely fast, sensationally loud and dripping with technology and extravagance. It’s also one of the most approachable supercars on the market and won’t make you look like a fool.

Whether you’re a seasoned track-day warrior or someone who just wants to feel like a boss on a weekend getaway, the GT 63 will fit the bill.

It’s not cheap and it’s no welterweight, but what it delivers is pure theatre, the kind of adrenaline-pumping excitement that’s becoming increasingly rare in a world shifting to silence and software.

If you’ve got the cash – and the stomach for it – the GT 63 isn’t just a car. It’s a rolling celebration of combustion-powered excess.
