Mateschitz: We need more F1 races like this one

Formula 1 would be in better health if there were more races like the drama packed Austrian grand prix.

That is the claim of Dietrich Mateschitz, the owner not only of F1's two Red Bull teams but also the picturesque scene in the Styrian mountains of the weekend's race action.

Asked if he is happy with the spectator numbers from the Red Bull Ring event, the Austrian billionaire told Speed Week: "We know already that Formula One is not exactly booming. But we would only need more [F1] races like this one and it would change quickly."

"If Ferrari and ourselves are able to put Mercedes under even more pressure, then the interest will rise again," said Mateschitz.

Red Bull's own performance boost recently - which saw Max Verstappen win in Spain last month and finish second in Austria - has been thanks largely to the team's unbranded engine supplier Renault, he admitted.

"We are absolutely satisfied with the progress of our engine partner," said the 72-year-=old. "We now expect another 20 horse power around the Japanese grand prix, which will bring two or three more tenths per lap."

Asked why he thinks Renault has suddenly leapt forward, Mateschitz answered: "The change in management was crucial."

"There are once again racers at work, bringing the necessary commitment and passion. That's why we extended the contract until 2018, but already for 2017 it is looking good," he added.
