Fastest Documented. Most Powerful Documented. Award-Winning. Benchmark Established.

Rarely does a vehicle emerge that completely redefines what enthusiasts believe possible from a luxury performance sedan.

This RENNtech 1-of-1 Mercedes-AMG GT63 S Edition One, known throughout the enthusiast community as "The Bullet," stands as the fastest and most powerful documented GT63 S in the world.

Developed through an extensive collaboration with RENNtech, this extraordinary vehicle represents the culmination of years of engineering, refinement, and relentless pursuit of performance excellence. Combining the exclusivity of Mercedes-AMG's highly sought-after Edition One package with unprecedented performance, it delivers hyper-supercar acceleration while retaining the luxury, sophistication, comfort, and drivability expected of AMG's flagship four-door coupe.

Unlike many high-horsepower vehicles that rely on E85 fuel, hybrid assistance, or nitrous oxide to achieve headline numbers, this vehicle was engineered through premium hardware enhancements, advanced calibration, and dedicated 93-octane and 100-octane performance tuning. The result is 1,200+ horsepower from a twin-turbocharged V8 powerplant while maintaining exceptional street manners and everyday usability.

With under 7,000 miles, this RENNtech 1-of-1 Edition One represents the pinnacle of GT63 S achievement—fastest documented, most powerful documented, and award-winning—and has established the benchmark by which all other GT63 S vehicles are measured.

The AMG GT63 S Edition 1 features additional performance and weight saving upgrades, namely the Forged Magnesium wheels and Nitto 555 tires that helped propel the AMG GT63 Edition One to a world record 9.79 second ¼ mile run, documented in the RENNtech Blog. Additional customer installed upgrades include Forged Magnesium Wheels and Nitto 555 tires ($18,300), XPEL PPF, Ceramic Coating and custom pinstriping ($22,500).
