Sauber says Formula 1 better than everFormula 1 has never been better or more exciting than it is now, reckons Peter Sauber.

Having produced seven different winners from the seven races held so far, and with teams having had to work hard to unlock the secrets to Pirelli's 2012 rubber, F1 has got used to witnessing some unpredictable grands prix. But although the topsy-turvy nature of the campaign has led to some criticisms that F1 results have become too much of a lottery, Sauber is adamant that the racing has never been as good.

"As far as I can see it's just a handful of people in the paddock who can't get used to not knowing by Friday who's going to win on Sunday," he said. "I think the fans see it in a completely different light. They're delighted with the unpredictability, the sheer variety and the unbelievably close competition.

"I've been in Formula 1 for 20 years now and for me it's never been better or more exciting. That's partly down to Pirelli, who are supplying the tires for this show."

F1's previous record of different winners from the opening races was five back in 1983, but this year Mark Webber in Monaco and Lewis Hamilton in Canada have helped increase that tally by two so far.
