Singapore a tough race course but still a favourite
Drivers raring to go in night race, with steel kerbs to enhance safety
Singapore's fifth Formula One night race is as tough as ever, but there is no curbing the drivers' enthusiasm this year.
Steel kerbs are being used on the Marina Bay street circuit this weekend, after rubber ones came loose at last year's Friday practice sessions.
The errant kerbs caused delays and raised safety concerns, but organisers are confident they have nailed down the problem this year.
Eleven of the track's 23 corners will feature the sturdier, made-in-Singapore kerbs, and new holes have been drilled into the tarmac to secure them.
