HANOI, Vietnam – The Vietnam Grand Prix Corporation, promoters of the Formula 1 VinFast Vietnam Grand Prix, has released an updated layout of the Hanoi Circuit.

Hanoi marks F-1’s newest track and will host the the pinnacle of motorsport for the first time April 3-5. The inaugural Formula 1 race in Vietnam will debut in the Southeast Asian country for the third round of next year’s 22-race FIA Formula 1 World Championship.

The tweak to the final section of the Hanoi Circuit will now see the total number of corners increase to 23 – making it the only track alongside Singapore’s Marina Bay Circuit to have as many – with the track also extending from its original length of 5.565 km to 5.607 km.

The slight change was decided upon after further consideration of the surrounding geographical conditions and has been fully supported by both F-1 and the FIA, who have been working closely with the event organizers to ensure all changes have been carried out according to standard regulations.

The new turn 23 is a 100-percent left turn, where the track widens out again to 15 meters before leading on to the start/finish line for one last push by the drivers when they race in Hanoi for the first time in Formula 1’s history next April.

The Hanoi Circuit itself is a unique hybrid design, fusing a street circuit’s characteristics with a permanent track layout. The first of its kind to be developed in partnership by Tilke Engineers and F-1’s own motorsports division, Hanoi is set to become one of the most challenging and sensational circuits in the sport.

With high-speed corner sequences not seen at any other pure street tracks and as many as three overtaking points where cars will have the potential to duke it out side by side, Hanoi is designed to deliver spectacular racing.
