This tuner has worked some serious magic.
Not too long ago we saw German tuner G-Power unveil its ferocious tuned version of the BMW X6 M. The tuning company managed to push the already high-performing SUV to deliver a monstrous 650 hp and 612 lb-ft of torque. G-Power has now set its sights on tuning the X6 M’s little brother, the X5 M, and the results are nothing short of spectacular. In fact, the results are so good that tuner apparently managed to make the X5 M even more powerful than its X6 M project.
The X5 M’s 4.4-liter twin-turbocharged V8 was tuned from its original 567 hp to an astonishing 690 hp. The car also pumps out a massive 667 lb-ft of torque. This incredible fete was accomplished by either remapping the stock ECU or replacing it entirely with a new ECU. G-Power also added a high performance stainless-steel exhaust system and completely did away with the X5 M’s top speed limiter. The G-Power BMW X5 M also rides on a set of super light weight forged alloys crafted from aircraft-grade aluminum.
