As standard, the BMW X5 M Competition and Mercedes-AMG G 63 are two very impressive, high-performance SUVs but that hasn’t stopped G-Power from announcing a bunch of tuning packages for the duo.

The first upgrade that G-Power has developed for the X5 M Competition and the G 63 is the GP-700 kit that works with both the BMW’s 4.4-liter twin-turbocharged V8 and the G 63’s 4.0-liter twin-turbo V6, lifting both vehicles up to 700 hp. Torque from the X5 M Competition also rises to 850 Nm while it has grown even further to 950 Nm in the Mercedes.

 

For those looking for even more power, G-Power also offers its GP-750 performance software. This upgrade boosts both to 750 hp while the BMW gets 900 Nm of torque and the Mercedes benefits from 1,000 Nm. Complementing the software changes are sport downpipes for both models. G-Power also tweaks the central powertrain control module of the G 63 to achieve its monumental torque figure and unlock its top speed.

Last but certainly not least is the GP-800 upgrade. Grunt from the X5 M Competition sits at 800 hp and 950 Nm while the G 63 churns out 800 hp and 1,050 Nm. Both models are equipped with new turbochargers to achieve these significant power gains. The G-Class is also equipped with a GP-Deeptone exhaust system with adjustable valves. G-Power’s tuned BMW X5 M Competition is dubbed the GX5M Bi-Turbo while the G 63 is now badged the GP 63 Bi-Turbo. Both can be equipped with the tuner’s in-house 23×11-inch Hurricane RS and Hurricane RR forged wheels.
