Porsche 911 Turbo (930) 1975>1989 - Though obviously 911-based, the Turbo Carrera was so heavily modified, both structurally and mechanically, that it was given its own factory type number: 930. The 930 was the fastest road car Porsche had ever produced, yet road-testers found it docile around town and blessed with handling that was surprisingly benign for such a potent rear-engine machine. All this moved one journalist to describe it as "the finest blend of ultimate performance and refinement I have ever come across," a view that found wide agreement the world over.
