Grand Prix of America promoter Leo Hindery Jnr is adamant he remains "100 per cent committed" to the project despite confirming a postponement of the race until 2014.
Infrastructure issues for the event at Port Imperial in New Jersey on the bank of the Hudson River, and with Manhattan as a backdrop, means the grand prix initially scheduled for June 16 next year has been put on hold for 12 months.
Hindery Jnr said: "We are going to be racing at Port Imperial, unfortunately just not as soon as we hoped and expected. We promised (New Jersey) Governor (Chris) Christie, the towns (of Weehawken and West New York), the sport and its international fans the best possible experience. Unfortunately, we need additional time to ensure that happens."
He went on: "But we remain 100 per cent committed to the Grand Prix of America at Port Imperial, and the race could have no better partner and friend than the CEO of Formula One, Bernie Ecclestone. We benefit greatly from his experience and counsel, and from his support."
Earlier Ecclestone confirmed to Press Association Sport the event would not happen until 2014, highlighting the difficulties relating to the building of the facilities.
Via a statement GPA officials claim "significant progress has been made toward developing the race, including substantial construction of the first garage and other permanent facilities".
Inroads have also been made in light of extensive track engineering and operations planning, hiring of senior staff and partnering with key vendors to manage hospitality, security, transportation planning and operations, and ticket sales.
However, they cite "additional time needed for the development of complex Hudson Riverfront facilities and for finishing the second pits and paddock garage on the site".
Reflecting on the problems, Ecclestone said: "The reason is because they didn't quite know what they were doing. They got all the permissions together. Everything was done, that was all fine, but then they missed the boat a little on some financing that was coming in.
"Everything is set up, but it's now too late to finish on time."
