The 2019 Mercedes-AMG GT63 S is already a performance benchmark, but this example takes power to a new level. This specific car received the limited-edition RENNtech RIIIx package at the tuner’s Florida headquarters. The RIIIx is celebrated as the first R-Line package to produce over 1,000 wheel horsepower. It transforms the sedan into a true four-door hypercar. This 2019 AMG GT63 S RENNtech is a thoroughly documented and tested machine.
The RENNtech Performance Philosophy
RENNtech ensures every RIIIx-equipped car is dyno tested and tuned in-house. This guarantees that the massive power ratings are completely accurate and documented. The resulting performance is staggering, with 0–60 MPH times tested at just 2.44 seconds. Furthermore, the RIIIx completes the quarter mile in a breathtaking 9.9 seconds at 139 MPH.
Extreme Engine Enhancements
The power upgrades begin with RENNtech Stage II turbochargers and a high-flow fuel system. An upgraded intercooler keeps the dense charge air cool under heavy boost. Custom ECU and TCU calibrations handle the air, fuel, and shifting demands. The motor also receives stainless steel downpipes and sport mufflers with adjustable valves.
Power, Engine Specs, and Performance
The heart of the beast is the twin-turbocharged 4.0-liter V8 engine. RENNtech officially rates this motor at an astounding 1,196 horsepower. It generates an equally impressive 927 lb-ft of torque. Power is flawlessly managed by an AMG Speedshift automatic transmission. The factory 4MATIC+ all-wheel-drive system ensures the incredible output is usable.
The Aero 1 Carbon Fiber Package
A significant cosmetic upgrade is the Aero 1 carbon fiber package. This adds a full carbon hood with striking Blue carbon intakes. A multi-piece front splitter, canards, and side skirts improve aerodynamics. The look is finalized with a carbon fiber rear diffuser and a prominent fixed rear wing. The Brilliant Blue Magno exterior is protected by a paint protection film and ceramic coating.
Custom Interior and Unique Touches
The cabin features a truly bespoke look, starting with a Linen suede starlight headliner. Custom AMG sport seats are upholstered in Linen with unique Blue carbon backs. Linen stitching contrasts against the Blue dashboard and door panels. Carbon fiber interior trim is utilized extensively throughout the cockpit. A custom plaque, signed by RENNtech founder Hartmut Feyhl, authenticates the build.
