G-Power AMG GT R Pro: 800 HP Beast

28 Mar, 2025
800 HP AMG GT R Pro by G-Power

G-Power, best known for tuning BMWs, has once again pushed the limits—this time with the Mercedes-AMG GT R Pro. While G-Power’s expertise extends to Lamborghini, Porsche, and Mercedes-AMG, this latest project showcases what happens when extreme engineering meets raw performance.

A Factory-Fresh Look with Insane Power

At first glance, this Mercedes-AMG GT R Pro retains its factory aesthetics. The front bumper, grille, side skirts, rear diffuser, and wing remain untouched, staying true to the car’s aggressive design. Even the black decals on the yellow body and the front fender vents come stock. But don’t be fooled—this beast is far from standard.

The real magic happens under the hood. G-Power has transformed the 4.0-liter bi-turbo V8, boosting output to an astonishing 800 PS (789 HP / 588 kW) and 900 Nm (664 lb-ft) of torque. This upgrade doesn’t come cheap, with a price tag of €44,786.48 ($46,660) in Germany.

Power Upgrades at Different Price Points

If 800 PS feels like overkill, G-Power offers more affordable tuning options:

  • 690 HP (700 PS / 515 kW) & 850 Nm (627 lb-ft) – €10,580.49 ($11,025)
  • 670 HP (680 PS / 500 kW) & 800 Nm (590 lb-ft) – €15,340.49 ($15,980)

Each package enhances the AMG GT R Pro’s performance, ensuring thrilling acceleration and sharper throttle response. Given that the stock model comes with 577 HP (585 PS / 430 kW) and 700 Nm (516 lb-ft) of torque, these upgrades make a significant difference on the road and track.

Performance Mods Beyond Power

G-Power’s tuning isn’t just about power gains. Customers can also upgrade:

  • Turbochargers, exhaust systems, and downpipes for maximum performance
  • Custom steering wheels with carbon fiber designs
  • Premium leather interior reupholstery in various colors
  • Velour floor mats for a refined cabin feel

The featured Mercedes-AMG GT R Pro sports yellow accents, an aftermarket sports steering wheel, additional carbon fiber trim, and a custom plaque on the center console. The wheels also appear to be from G-Power’s Hurricane series, available in two sizes for a perfect fit.

The Ultimate AMG GT R Pro Upgrade

For Mercedes-AMG enthusiasts, G-Power’s upgrades offer a blend of extreme power, customization, and exclusivity. Whether you're chasing 800 PS or just looking for a refined interior, G-Power ensures your AMG GT R Pro stands out in both performance and aesthetics.
