The new GT 63 PRO is a weird one — initially I struggled to understand where it fitted into the AMG GT range. But driving it properly on UK roads has completely changed my perspective!
For the last four years, Formula 1’s Mercedes-AMG Safety Car was the legendary AMG GT Black Series — one of the greatest AMGs ever built, and personally the best car I’ve ever owned. Now, after 30 years of Mercedes-AMG Safety Cars in Formula 1, that car has been replaced by the new #AMG GT 63 PRO.
The PRO takes the already brilliant GT63 and turns it into an endurance-focused performance package: 612HP and 850Nm from its 4.0-litre cross-plane twin-turbo V8, additional drivetrain cooling, active cooling for the differentials and 4MATIC+ transfer case, increased brake cooling, huge ceramic brakes and a significantly revised aero package. It’s not simply about going faster once — it’s designed to keep performing lap after lap — while maintaining the usability of the new gen car.
But how much of that actually matters on the road? And does it make the PRO genuinely worth choosing over the regular GT63 — or even my own GT55? To find out, I had another rather useful car at home at exactly the same time: the latest T-Hybrid Porsche 911 Turbo S!
So this is much more than a normal GT 63 PRO review. We compare both cars side-by-side for design, practicality, interior space and sound, before driving them back-to-back. The Porsche remains one of my favourite sports cars and is devastatingly capable — but the AMG brings something to the experience that the new Turbo S arguably struggles to match. And yes… the exhaust comparison gets rather one-sided!

We also take a detailed look at the future of the AMG GT family. AMG has officially confirmed the next GT Black Series alongside its future GT3 customer racing car, with both being developed through the Track Sport programme. The prototypes look utterly wild — huge active aero, AMG ONE-style front wheel-arch elements, side-exit exhausts, an enormous diffuser and a soundtrack that bizarrely evokes the old naturally aspirated 6.2-litre AMG V8.
And with such an enormous gap developing between the usable £180k-ish GT 63 PRO and what AMG itself calls its “most extreme Black Series ever”, I think there may still be one very important AMG missing from the range… The GT R!
As for the GT 63 PRO isn't about reinventing the new AMG GT. It’s about fortifying it. You retain the everyday usability, huge boot, luxury interior and all-weather ability of the current GT, but add the cooling, brakes, aero and chassis hardware required to withstand far more serious use.
And as AMG moves towards a new generation of engines, the PRO may also end up representing one of the final versions of the angry, cross-plane V8 AMG GT we know today.
That suddenly makes this car feel rather more special.
