But The Times said F1's chief executive wants the floodlit roofs of the olympic stadium and ice rinks to provide the backdrop for the race in future.
"The idea is a clever one," said correspondent Kevin Eason, "given that the olympic park looks more like a vast car park than a picturesque sports arena in daylight."
Ecclestone confirmed: "I think they would go for the idea.
"At night the stadiums are very colourful with lots of lights and the backdrop to a race would be fantastic.
"It (the surrounding area) was a bit of dump, quite honestly," he admitted. "But they have spent a lot of money and there is a lot going on and the place is changing all the time."
