Bangkok unveils official details of proposed 2028 Grand Prix circuit

The first official concrete details of the proposed Bangkok Grand Prix have been released in Thailand, including full circuit maps, layout statistics and the framework for a 5-year race contract starting in 2028.

The release came via a public questionnaire inviting residents and fans to share opinions on the project, but the real headline was the inclusion of 2 detailed maps and an outline of the planned street circuit, offering the clearest picture yet of what a future Bangkok Grand Prix would look like.

According to the published data, the proposed track will measure 5.732 kilometres with 18 turns, running clockwise through the Chatuchak district north of the city centre. The circuit would accommodate more than 108,000 spectators and is split into 8 zones across a mix of transport hubs, commercial areas and major parks.

The layout threads past the new Krung Thep Aphiwat Central Terminal Station, the Mo Chit Bus Terminal, the Chatuchak Weekend Market and PTT’s industrial complex. It also cuts through 3 parks, namely Railway Park, Wachirabenchathat Park, Chatuchak Park and Queen Sirikit Park.

Key performance details include a 1.2-kilometre back straight between Turn 13 and Turn 14, which ends in a 320-degree right-hand corner. The start-finish straight features an immediate right-hand kink before drivers commit to a demanding 290-degree right-hand turn 1, which is expected to become a focal challenge of the lap.

The plan lists 8 fan zones and around 24 grandstands, including one at turn 5 that appears to overhang the circuit on the preliminary map. The infield pit building will be a permanent multi-purpose structure, similar to the facilities in Monaco and Las Vegas, enabling year-round use.

The Thai government is targeting a contract running from 2028 to 2032 as it pushes to secure the race and bring Formula 1 to the streets of Bangkok for the first time.
