Tweaks made to Singapore track layout

The organisers of the upcoming 2015 Formula 1 Singapore Airlines Singapore Grand Prix expect closer racing and more overtaking at this year’s night race after Formula One racing’s governing body, the FIA, approved modifications to the Marina Bay Street Circuit.

The changes, which will affect Turns 11 to 13, are the result of enhancements to Singapore's Civic District.

The right-handed Turn 11 will remain, but will be re-aligned to sit tighter with the left-hand side of Fullerton Road, resulting in a slightly slower corner speed compared to 2014.

The left-hand Turn 12 will also be modified slightly so that drivers now enter the left lane of Anderson Bridge, before accelerating towards Turn 13 at 200km/h (124mph) - which is a similar speed to last year.

The Turn 13 hairpin meanwhile will be widened by one metre to enable more passing opportunities.

The year's race takes place September 18-20.
