Chassis

Porsche Supercup cars adhere to a rear-engined rear-wheel-drive design. A roll cage serves as a carbon-fibre space frame chassis and is covered by a multiple-gauge sheet metal body. They have a closed cockpit, fenders, a rear wing, and an aerodynamic splitter. Each team may purchase cars and engines from other teams.

The car has a front MacPherson strut suspension, and a rear Multi-link suspension. Brake discs must be made of steel and may not exceed 380 mm (15 in) diameter. The only aerodynamic components on the vehicles are the front splitter, rear wing, solid polycarbonate glass window in the windows only, and side skirts. The use of rear diffusers, vortex generators, canards, wheel well vents, hood vents, and undertrays are prohibited.

Porsche Supercup cars are required to have at least 1 working windshield wiper installed on the car for all tracks as a part of the road racing rules package.

Driver championship

Points are assigned to the first 15 finishers of each race and all races count towards the championship. To receive points, a driver must compete in multiple races per season. Since 2008, there have been two bonus points awarded for the driver who secures pole position in qualifying.

In the case of a tie, Porsche Supercup will determine the champion based on the most first-place finishes. If there is still a tie, Porsche Supercup will determine the champion by the most second-place finishes, then the most third-place finishes, etc., until a champion is determined. Porsche Supercup will apply the same system to other ties in the rankings at the close of the season and at any other time during the season.

Team championship

The points of the two best drivers of each team are added up. At the end of the season Porsche rewards the three best placed teams with prize money.
