Porsche Carrera Cup

The cars are specifically built by Porsche for one-make racing, but are visually and mechanically quite similar to road-registrable 911s of the same generation.

Now in its 39th year it has been one of the world's best known Pro-Am GT series and helped to progress many future World Endurance Champions, Le Mans winners and today is the primary feeder for the Porsche Supercup with many racing teams contesting both series.

The early 2000s saw a proliferation of Carrera Cups with Great Britain, Australia, Asia and Scandinavia all starting in a four-year burst with Italy following in 2007.

Dutch driver Larry ten Voorde is currently the defending champion of the Porsche Supercup.

The one-make GT series model has also been used for other Porsche models, usually the entry level Porsche of the time, 924, 944, 968 and Boxster and has proliferated to other manufacturers as well; Ferrari Challenge, Lamborghini Super Trofeo, Trofeo Maserati, Audi R8 LMS Cup, Lotus Cup, MGF Trophy and a multitude of series based on the Mazda MX-5.
