Looks like the 2017 Formula 1 Singapore Airlines Singapore Grand Prix is back on track for September, after previous reports of an October date for the race. At the Annual General Assembly in Vienna, the Federation Internationale de l'Automobile confirmed the new dates to be September 15 to 17 in 2017.
With this change, the Malaysia Grand Prix will now be held on October 1 after the Singapore Grand Prix.
