German BMW specialist G-Power has been branching out into Mercedes as of late. The company’s latest Merc builds use the AMG GT 63 S Coupe as foundations.

G-Power’s business sensibility casts a broad demographic net when it comes to disposable income, and the trio of performance packages offered for the GT 63 S Coupe collectively offers a wide range of investment levels.

The numerical figures in the performance range indicate the new horsepower rating. As an entry-level package, the GP-700 will suffice for many; at €2,500, it’ll buy a 10% horsepower boost, bringing the rating to 690. The middle of the range is the GP-750, which will bring you up to 740 HP from the production car’s 630. Top of the heap is the GP-800, which includes G-Power’s engine software,  bigger turbos, stainless exhaust, and other components.

Pricing for the full monty comes to just under €20,000.
