Shah Alam Circuit or Batu Tiga Speedway Circuit was a racing circuit in Shah Alam, Selangor, Malaysia. The circuit layout was designed by Dutchman John Hugenholtz.
The circuit was opened in 1968. The 1968 Malaysian Grand Prix was held there on 8 September as a Formula Libre race and was won by Indonesian Hengkie Irawan driving an Elfin 600.[1] The circuit was the venue for the Malaysian Grand Prix until 1982, with the starting field consisting alternately of vehicles from the Formula Atlantic, Formula Pacific or Formula 2. The last Malaysian Grand Prix race held in Shah Alam was held for Formula Brabham in 1995.
The circuit was closed in 1977 after an accident that killed six children, although it later reopened after improvements of fences and guard rails around the track were carried out.[2] In 1985 the track was lengthened from 3.38km (02.1miles) to 3.693km (02.295miles) with the addition of the curve 11.[3] In the same year, the first international racing event was held. Titled as the 1985 800 km of Selangor, the race was the tenth and final round of the 1985 World Endurance Championship, and was won by Jacky Ickx and Jochen Mass driving a Porsche 962C.
The circuit hosted rounds of the Superbike World Championship in the 1990 and 1991, and from 1991 to 1997 it hosted the Malaysian motorcycle Grand Prix. Mick Doohan is the all-time leader in motorcycle Grand Prix victories at the venue, winning the event four times. The motorcycle Grand Prix was later moved to the Johor Circuit, and later to the Sepang International Circuit.
In 2003 the circuit was sold by Selangor state government to a property developer, which then developed the area into a luxury housing project by the name D'Kayangan.
