The BMW X5 M can speak for itself, but G-Power has done a bang-up job in increasing its vocabulary.

The team at G-Power altered a standard X5 M and supercharged it with their own special touch. The X5 M rolls off the factory floor with plenty of juice; a powerful 4.4-liter twin-turbocharged V8. The standard model produces a not-so-standard 575 hp and 750 Nm of torque. G-Power presents X5 M drivers with a series of power modification options to make their growling Bimmer into a real screamer.

The Bavarian tuning company offers three tiers of packages for the X5 M. The Stage I mods alter the standard build to produce 650 hp and 850 Nm. Stage II includes a new set of downpipes to up the hp another 50, while pushing the torque to 850 Nm. Finally, the Stage III tune results in an output of 750 hp and 980 Nm of torque.

BMW’s X5 M will already set buyers back at least $100,000, and the full upgrade tuning package from G-Power will add roughly $22,050 to that price. But G-Power’s expanded lexicon will allow you to speak far more fluently on blacktop and back road.
