Thanks to new turbochargers and software, plus a few other parts, Merc’s super SUV benefits from a significant increase in power.
The German roadster now packs a mighty 493 hp and 516 lb-ft of torque.
G-Power offers four power kits for the Mercedes-AMG GT R, ranging from 650 PS to 800 PS.
The tuner’s asking a decent €1,400 for this power upgrade, which makes the M2 an absolute beast.
Forget about the M4, as this tuned M2 Competition now has supercar power.
This tuned M5 F90 also gets a power upgrade, with its 4.4-liter twin-turbo V8 now producing 700 PS.
The tuner can also extract up to 739 horsepower from the current X5 M just by updating the software.
The tuner’s ultimate upgrade package for the 440i Gran Coupe costs €11,000, excluding installation .
The tuned SL63 has a top speed in excess of 340 km/h (211 mph) and sprints to 62 mph in 3.5 seconds.
If you want M8 performance numbers, the M850i from G-Power has you covered with 660 horses.
Is the M8 taking too long to show up? You can get an M850i and take it to the German tuner instead.
The tuned Merc rockets from 0 to 62 mph in 3.1 seconds and tops out at more than 186 mph.
