Porsche 911 GT3 Cup 2021
 Several countries now have their national Carrera Cup or GT3 Cup – the official name varies according to local convenience. In 2005, Brazil started to have its championship, called Porsche GT3 Cup Challenge Brazil. Success can be measured by the number of participants: in just one year, the number of registered cars has grown from 11 to 24. In addition, the Porsche GT3 Cup Challenge Brazil is one of the preliminary categories of the Formula 1 Brazilian Grand Prix.
 The Porsche GT3 Cup Challenge Brazil is an automobile competition in Brazil that uses only Porsche GT3s prepared for the races. It differs from other brand competitions around the world in that it is entirely organized by a single company.
