The Porsche GT3 Cup Challenge USA by Yokohama is a one-make racing series based in North America using Porsche 911 GT3s.
The Porsche GT3 Cup Challenge USA by Yokohama entered its 11th season in 2015 as one of the largest of Porsche’s 20 single-make Cup Challenge series in the world. The series produces intense, exciting competition for semi-professional and aspiring professional drivers in the world’s most produced and iconic race car, the Porsche 911 GT3 Cup.
Racing is divided into two classes – Platinum Cup, featuring the 2014 and 2015 Porsche 911 GT3 Cup car, which is based on the seventh (current) generation of the street car; and Gold Cup, which is for the previous iteration (model years 2010-2013) of the race car. A Masters Championship also is conducted in Platinum and Gold classes. Each class is awarded with its own podium at the end of every race and individual champion at the end of every season. Points are awarded by finish in class.
The series is sanctioned by the International Motor Sports Association, and is a support series to the United SportsCar Championship.
