The Porsche Cayenne S is one quick SUV to begin with. The Cayenne Turbo is ridiculously fast. Having driven one, nothing that large should be able to move that fast. But since fast is never fast enough Porsche tuner Gemballa has taken and tuned a Cayenne Turbo. There are no specs, just some pretty pictures and a lot of carbon fibre, but if I were a gambling man I'd guess this tuned Cayenne produces somewhere in 700-750hp range. At what point does an SUV stop being an SUV? I think we might have hit that point with this beast.
