Clark International Speedway, abbreviated as CIS, is a motorsport venue at the Clark Freeport Zone in Mabalacat, Pampanga, Philippines.[1]
It was built on November 15, 2008. The circuit features 18 turns and runs in a counter-clockwise direction.[2] Clark International Speedway hosts both 2- and 4-wheeled events. This includes the Philippine Superbike Championship, Toyota Vios Cup, Philippine GT Championship, Philippine Touring Car Championship, and FlatOut Race Series. The layout also has a drag strip that hosts the National Drag Racing Championship.
The Philippine Sports Commission and V8 Supercars CEO Martin Whitaker announced that the circuit would hold a round of V8 Supercars on 10–11 November 2012, but series management never officially ratified the event and it did not appear on the calendar.[3]
The circuit hosted the second event of the 2016–17 Formula 4 South East Asia Championship. This was the first event in the motorsport venue to be certified by the Fédération Internationale de l'Automobile.[4]
Aside from car races, CIS also hosts several motorcycle sports including the Pirelli Petron National Motorcycle Racing Championship and the Philippine Superbike Championship held every May to October.
