Formula 1 chiefs have been urged to learn the lessons of why the Canadian Grand Prix was such a spectacle.
After tire dramas in Montreal helped deliver one of the most exciting races of recent seasons – with 60 overtaking moves during the event – leading figures within the sport believe that when it comes to framing new regulations, F1 should take into consideration exactly what the factors were that made that race so good.
Red Bull Racing team principal Christian Horner believes that Canada showed perhaps too much focus had been spent worrying about aerodynamics having the biggest effect on the racing.
"There was this myth of aerodynamics being the root of all evil, but in Canada you could quite clearly see tires have a much bigger influence on cars being able to race each other," he said. "In fact, you could say now it has a bigger influence than perhaps aero does."
Lotus technical chief Mike Gascoyne thinks one of the key lessons to come out of Canada was that it will be important for tire regulations to be framed in such a way to make one of the available compounds very difficult to work with.
"If you were going to write the tire rules for how you wanted races to be, they would be like Canada," Gascoyne said. "You had changing strategies, overtaking and lots of excitement. It was exactly what F1 needs, and it's proven that the argument for one tire being very marginal is very strong."
He added: "Just look at the different way people used the tires. Some used the super-soft at the start and we ran it for 18 laps at the end – which was fine. [Vitaly] Petrov stopped five laps later than us, he came tearing up to us and we thought we were in trouble, but by the time he was up to us his tires had dropped off and we were able to defend. That was good racing."
McLaren team principal Martin Whitmarsh thinks Canada – allied to some similarly exciting races this season – has proved that there is not that much wrong with the current F1 regulations despite the poor season-opener in Bahrain.
"Lots of people want to write negative things, but we've now had seven fantastic races," said Whitmarsh, referring to Bahrain being the only boring event so far this year. "In Turkey, after 40 laps, you had four cars split by three seconds – and there was a lot of pressure there. Then we had Canada.
"In F1 you are not supposed to follow closely and you cannot overtake, but Canada was a great race. We've been very fortunate and have had some classic racing this year."
