Best Cayenne, is by far the Turbo S: exudes quality, power and style, all in one beefy package. It has the sound of an angry snarling beast, at full throttle. Porsche packed all their very best features and components, in the Cayenne Turbo S. The best year of Cayenne Turbo S is the 2013 model, as most catastrophic failure points has already been addressed. This Swiss Army Knife of power SUV is the pinnacle of luxury and utility... all wrapped in one technology-packed, uber-vehicle.
