About Clark International Speedway
Overview
Clark International Speedway, known as CIS, is a motor racing circuit in the Clark Freeport Zone at Mabalacat in the province of Pampanga, Philippines. The venue sits on Panday Pira Avenue and hosts both car and motorcycle events. Alongside the main road course the site has a go-kart track and a one-kilometre drag strip, and the circuit is also hired out for private events and manufacturer track days. It hosts rounds of national championships such as the Toyota Gazoo Racing Philippine Cup, and in October 2025 it held the three-day Clark International Festival of Speed.
Technical Specifications and Track Features
The Full Circuit, in use since 2012, measures 4.189 km and has 18 turns, with a minimum track width of 12 metres. It holds FIA Grade 4 accreditation. The lap starts on a long main straight beside the pit garages and paddock, which leads to a tight complex of corners at the north-eastern end of the property. From there the track returns along a long section and folds back on itself through two long hairpins before a twisting infield section in the west, after which the final corner feeds back onto the main straight. The circuit layout map places the start and finish line at the beginning of the main straight. The race lap record of 1:55.607 was set by Daniel Cao in a Mygale M14-F4 during the 2017 Formula 4 South East Asia Championship.
Facilities and Specialized Areas
The pit straight is lined by a row of garages with the paddock behind them, and the weigh-in area and a grandstand are located at the south-western end of the straight. During the 2025 Festival of Speed the pit area was turned into an activity centre and trade show for manufacturers and aftermarket brands, and a car meet was held on the starting grid after sunset. The venue also has a separate go-kart track, and the one-kilometre drag strip is used for the National Drag Racing Championship.
History
Construction began in 2007 and the circuit opened on 15 November 2008. In its first years the management ran open practice days for cars and motorcycles at a daily fee. In 2011 the Philippine Sports Commission and V8 Supercars announced a championship round at Clark for November 2012, but the series never ratified the event and it did not take place. The present Full Circuit layout dates from 2012. The second round of the 2016-17 Formula 4 South East Asia Championship was the first FIA-certified event held at the venue, and the series raced there again in 2017. Over the years CIS has hosted the Philippine Superbike Championship, the Toyota Vios Cup, the Philippine GT and Touring Car championships, the FlatOut Race Series and the national motorcycle racing championship, as well as series such as Radical Challenge Philippines and Formula V1. The circuit is run by MLT Unlimited Solutions Corp.
