The Sepang 1000 km Endurance Race is a 1,000-kilometre (620-mile) 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 1,800 cubic centimetres (110 cubic inches). 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 1,600 cc (98 cu in) cars have won two of three races held thus far.
Classes
The race is divided into 2 classes, for cars of 1800 cc and a second class for cars of 1600 cc or less.[1]
