Ahead of the inaugural race here last September, drivers said the bumpy, five-kilometre (three-mile) waterfront circuit offered virtually no chance of overtaking, although organisers thought it was possible in at least two places.
The changes come after consultations with the teams and the Federation Internationale de L’Automobile, the governing body for world motor sport.
Following consultation with the FIA and the teams, minor changes will be made to Turns One, 13 and 14 to further increase the potential for overtaking, whilst road surface improvements will be undertaken at Turns Five, Six and Seven, and revisions made to the pit-lane entry and exit as well as the Turn 22 runoff area.
“While the circuit and the event exceeded expectations around the world, as with any brand new event, there are always things which we now know we can do better,” explained Singapore’s technical and race operations director, Michael McDonough.
“Minor modifications are proposed on the track, at Turns One, Seven and 14 in order to improve overtaking opportunities whilst the main changes will be to the Pit Entry and Pit Exit to provide added margins of safety for cars entering and leaving the pit lane.”
The changes to Turn One will involve modification to the geometry to reduce corner speed so that it provides potential overtaking opportunities in the braking zone at the approach to the corner. The modifications will involve relocating the corner apex, reducing the corner radius and thereby cutting the estimated cornering speed.
