F1's provisional 2013 calendar sees New Jersey replace Valencia as Silverstone breaks free from Wimbledon final Although there are few surprises in the schedule, which is yet to be signed off by the World Motor Sport Council, it was still met with a few wide-eyed looks by the Formula One community out in Singapore. At 20 races, it equals 2012 as the longest in Formula One history, but with 13 of them now outside Europe and an unprecedented eight back-to-back race weekends, it looks to be the most brutal yet travel-wise. The highlight is undoubtedly the introduction of the eagerly-anticipated grand prix in New Jersey, using the Manhattan skyline as its backdrop. The American race has been paired with the ever popular Canadian Grand Prix in mid-June. It has been asterisked, however, along with those in Germany, Singapore and Korea, to indicate they are still subject to contracts being finalised and the tracks being ready. There is speculation that Singapore organisers are unwilling to meet Bernie Ecclestone's race-sanctioning fee, which was already thought to be as little as $12million per year. That compares to around $40 million per year for races in countries such as Bahrain. Singapore organisers are thought to be arguing that as the "Monaco of Asia," and with the set-up costs of a night race so vast, the race should, like the one in the Principality, not be subject to a hosting fee. 2013 Formula 1 calendar (Provisional) March 17: Australia (Melbourne) March 24: Malaysia (Sepang) April 14: China (Shanghai) April 21: Bahrain (Sakhir) May 12: Spain (Barcelona) May 26: Monaco (Monte Carlo) June 9: Canada (Montreal) June 16: America (New Jersey) * June 30: Britain (Silverstone) July 21: Germany (Nurburgring) * July 28: Hungary (Hungaroring) Sep 1: Belgium (Spa) Sep 8: Italy (Monza) Sep 22: Singapore (Marina Bay) * Oct 6: Japan (Suzuka) Oct 13: Korea (Yeongam) * Oct 27: India (Buddh International Circuit) Nov 3: Abu Dhabi (Yas Marina) Nov 17: United States (Austin) Nov 24: Brazil (Interlagos) subject to confirmation
