Formula 1 supremo Bernie Ecclestone has cast doubt on New Jersey hosting a Grand Prix in June 2013 despite a 10-year agreement announced in 2011.
Ecclestone said: "Maybe the New York race will be 2013. It's when, 2013 or 2014."
The East Coast race is likely to be coupled with Canada on consecutive weekends and would give the North America two rounds of the championship. Austin, Texas is due to make a debut on the 2012 calendar in November if its circuit is ready in time.

The US, a key market for F1 manufacturers such as Ferrari and Mercedes and some team sponsors, has not had a GP since Indianapolis in 2007.
Austin had looked unlikely to go ahead until an agreement over hosting fees was reached between Ecclestone and local organisers in December.
