9ff has established itself as a serious player in the pursuit of toppiling OEM's top-speed records, but the German tuner's range of modifications for Porsches spans the spectrum from mild to wild. Wild, in this case, includes the 9ff Vantage GTR. It's based on the Cayenne SUV and has nothing to do with the 911-rivalling Aston Martin, but the 9ff sport-ute packs a mighty punch. With a whopping 725hp on tap, the Vantage GTR leaves other modified Cayennes in its dust – make that a big cloud of dust – and straight into Gemballa territory, which is an insane place to spend any amount of time.
To match the power output, 9ff has decked out this Cayenne in Tumbler-worthy bodywork and sinister matte black finish, and is apparently even offering a revised front end to replace the stock model's angular headlights with round 911 units. See for yourself in the gallery below.
