FIA president Jean Todt has said that he is happy with Formula 1 at the moment.
The Frenchman told Italy's Radio Uno that life as the president of F1's governing body is "challenging and interesting", adding that those who constantly criticise the sport "do not understand much".
"F1 is in a good condition but we can always do better," said Todt. "Next year we have some interesting changes to the regulations, but already this year the championship is a fight.
"There's a dominant team, which is Mercedes, but it's up to the others to try to improve. In F1 history there have always been teams that dominate for a time.
"With the new engines we saw that Mercedes worked better than the others but there are teams now who are making progress and a promising recovery."
Next up on the calendar is the Hungarian Grand Prix in two weeks' time.
