Sepang 1000 km

The Sepang 1000 km Endurance Race is a 1000 km endurance racing event held annually since 2009 at the Sepang International Circuit in December. The race was created out of the success of the 12-hour Malaysia Merdeka Endurance Race, but unlike the MMER is a touring car race and is limited to cars with an engine capacity of under 1800 cc. Originally 1900 cc was the upper limit but this was reduced in 2011. Despite the engine power advantage of the larger-engined cars, Class 2 1600 cc cars have won two of three races held thus far.
