But Danner, also a commentator for German TV RTL, is worried.
"The most recent championships were, I think, the best there ever was," he told Playboy magazine.
"The reasons for this are clear. First, the technology is so developed that the cars are very reliable.
"Secondly, because of the regulations, the four engine manufacturers have been supplying practically equivalent engines.
"The introduction of the six cylinder engines is a huge technical challenge," Danner continued.
"The engines will play a much more important role, and so I am afraid of the effect that will have on the competition."
