|League type||GTR Sprint league|
|Organizers||New Dimension Racing|
The GT2 Challenge (GT2C) is a sprint based series, using restricted GTR cars.
The series aims to a sprint format, one driver to a car. Races are scheduled to be approximately 230 kilometres in length, with a rolling start. Drivers are not required to make a pit stop, but the race lengths make the no-stop strategy risky. Safety Car and Virtual Safety Car deployments add strategic changes.
