Aero and Aesthetics Combined

The Aero 1 carbon kit amplifies downforce with purpose. Blue carbon hood intakes, side skirts, and that menacing rear diffuser give it fighter-jet flair. Even parked, it looks like it’s moving.

1,196 Horsepower: The Numbers That Matter

Powering the AMG GT63 S RENNtech RIIIx is a 4.0L V8 dialed to a jaw-dropping 1,196 HP and 927 lb-ft of torque.

RENNtech’s Stage II turbo upgrade, high-flow fuel system, and ECU/TCU calibration elevate this car to hypercar territory. Turbo spool is ferocious.

A 2.44-second sprint to 60 mph and a 9.9-second quarter mile seal the deal. The 4MATIC+ system claws for grip, while stainless downpipes and adjustable valves deliver a sound worthy of the badge.

Built With Precision Engineering

This isn’t just bolt-ons and hope. RENNtech tested and tuned the car on their in-house dyno. The result is explosive yet refined power delivery that feels intuitive and confident.

Tailored Detail Throughout
