G-Power has only been modifying Mercedes products for a few years now, after focusing initially on BMW. However, they have since tuned several AMG variants, with the latest being the Mercedes-AMG GT 63 4-door coupe . This is a car that, even when stock, comes with 640 PS and 900 Nm of torque if you opt for the flagship 63 S variant. Thanks to G-Power though, you can build on those figures by choosing between three boost levels.

The first is the GP-800, which comes with 800 PS and 1,000 Nm of torque. Responsible for the extra grunt is the GP-800 performance software (€ 3,595 / $4,040), new turbochargers (€ 6,390 / US$ 7,180) and downpipes (€ 5,360 / US$ 6,022), as well as the sports air filters (€ 238 / US$ 267) and a stainless steel exhaust system (€4,850 / US$ 5,450).


The middle tier upgrade package (GP-750) gives you 750 PS and the same 1,000 Nm of torque as with the GP-800 package. The software is 2,995 euros (US$ 3,365), and you also get custom downpipes. Last but not least is the “starter” GP-700 performance package, which provides 700 PS and 950 Nm and costs 2,495 euros (US$ 2,800).

You also get minor cosmetic upgrades, which is why this modded Mercedes-AMG GT 4-door comes with the tuner’s own Hurricane RR forged wheels, which you can get in either 20-inches or 21-inches, at a cost of 7,950 euros (US$ 8,932) and 8,950 euros (US$ 10,056), respectively. Furthermore, a second rim model, the Hurricane RS, is currently in development.
