F1 boss Bernie Ecclestone would consider letting in a second Indian race in the future.
But the sport’s 81-year-old chief executive said there is no room on today’s 20-race calendar.
"We’ve got too many races now either in the championship or about to go in," he is quoted by Reuters. "So, later on maybe. Three or four years."
However, after a good crowd watched last year’s inaugural Indian grand prix in New Delhi, the grandstands have been much emptier on F1’s return visit.
Indian motor racing chief Vicky Chandhok said the biggest problem is the high ticket prices.
"There is a contract between the (Indian) GP group and formula one until 2015," he told CNN.
"Beyond that I do hope that we can sustain it, and if not maybe F1 will start to change their approach to rights fees and things like that."
Chandhok revealed that the Buddh circuit’s "very high" annual fee to Ecclestone is $40 million.
