Located in Sepang, Selangor, around 45 kilometres south of Kuala Lumpur and close to Kuala Lumpur International Airport, the Sepang International Circuit is one of Formula One’s most recognisable modern venues. Purpose-built at the height of Malaysia’s major infrastructure expansion in the late 1990s, Sepang quickly became known for its wide track, long straights, sweeping corners, and unpredictable tropical weather.
Designed by Hermann Tilke, the circuit was among the first of Formula One’s new generation of modern Grand Prix venues and set the template for many tracks that followed. Its broad layout allows multiple racing lines, while the combination of heavy braking zones and long-radius corners creates a demanding test for both car balance and tyre management. Add in the intense heat, high humidity, and sudden tropical downpours, and Sepang became one of the most physically challenging races on the calendar.
Sepang hosted the Malaysian Grand Prix from 1999 to 2017 and remains one of the most important motorsport venues in Asia. Even after Formula One’s departure, it has continued to stage major international racing, particularly in MotoGP, GT racing, and regional series.

Circuit
When was the Sepang International Circuit built?
Construction of the Sepang International Circuit began on 1 November 1997, and the venue officially opened on 7 March 1999. The project formed part of a major wave of development in Malaysia during the 1990s, with the government aiming to create a world-class motorsport venue close to the country’s new administrative and transport hubs.
The circuit was designed by Hermann Tilke, who would later become responsible for several other major Formula One venues around the world. Sepang was one of his earliest and most influential Formula One projects, and its design helped define the look and feel of many modern circuits that followed.
The main Grand Prix layout measures 5.543 kilometres and features 15 turns. It runs clockwise and is particularly noted for its wide track width, ranging from 16 to 22 metres, which gives drivers room to attack corners from different lines and improves overtaking opportunities.
One of Sepang’s most unusual features is the way its two longest straights sit almost parallel to one another, separated by a tight hairpin. The 0.927-kilometre back straight and the pit straight create a rhythm that encourages overtaking while forcing teams to find a compromise between straight-line speed and stability in the more technical sectors.
The circuit is also famous for its weather. Malaysia’s tropical climate means races at Sepang often took place in intense heat and humidity, but conditions could change very quickly with heavy rainstorms arriving with little warning. That unpredictability became one of the defining features of racing at the circuit.
In 2016, the track was completely resurfaced with support from Dromo, and several corners were reprofiled to place greater emphasis on mechanical grip rather than aerodynamic performance. The final corner was notably raised, encouraging a later apex and opening up different possible racing lines onto the pit straight.
When was the first Malaysian Grand Prix?
Sepang hosted its first Malaysian Grand Prix in 1999, the same year the circuit opened. The venue was officially inaugurated earlier that year by Prime Minister Mahathir Mohamad, who also played a major role in the wider infrastructure programme that brought the circuit into existence.
The 1999 race marked Malaysia’s arrival on the Formula One World Championship calendar and quickly became a popular fixture. Sepang’s wide layout, overtaking opportunities, and frequently dramatic weather often produced exciting and unpredictable Grands Prix.
During its time in Formula One, the circuit was home to many memorable moments. It became associated with major championship battles, changing weather strategies, and several high-profile incidents. The race remained on the calendar through 2017, hosting a total of 19 Formula One World Championship Grands Prix.
Despite its popularity among many drivers and fans, the Malaysian Grand Prix eventually ended due to rising hosting costs and declining ticket sales. The 2017 Malaysian Grand Prix was the last Formula One race held at Sepang.
Even after Formula One’s exit, the circuit remained an important international venue. It continues to host the Malaysian Motorcycle Grand Prix, GT racing, endurance events, and a wide variety of Asian and international series.
Sepang International Circuit lap record
The official Formula One lap record for the Sepang International Circuit is 1:34.080, set by Sebastian Vettel in a Ferrari SF70H during the 2017 Malaysian Grand Prix.
That remains the benchmark for the Grand Prix layout and stands as the final Formula One lap record set before the Malaysian Grand Prix was removed from the world championship calendar.
