Commercial rights holder Bernie Ecclestone has said Pirelli has had the biggest impact on racing in F1 this season, with '90 per cent' of the improved spectacle being down to the new tyre supplier.
Pirelli took over from Bridgestone as tyre supplier for the new season and was given the task of providing rubber that would degrade quicker.
Thus far, the new tyres have delivered exactly what was required bringing a new element of strategy into the racing as teams work out how best to make use of the tyres at their disposal.
"Only Pirelli would do it, and we must thank them,” he told Blick
. “It was brave and the show has improved. Michelin and Bridgestone refused to build tyres like this because they were worried about their image."
The new tyres have come into the sport at the same time as KERS makes a return and the new Drag Reduction System is implemented but Ecclestone again questioned the need for the latter innovations.
"The effect of the adjustable rear wing is not entirely clear, and KERS was never meant to be a passing aid but was instead for the message we give to the outside," he said. "Some have KERS, some don't, and the ones that do have spent up to $15 million when we really wanted to save. An incredible amount of money was spent and nobody knows why.
"If we wanted it for overtaking, we could have done it like the A1 series and just put in a button for a few hundred dollars. Environmentally-friendly technology is for touring cars. That's where it makes sense, because the cars you see there you also see on the street.
"If you compare Formula One with other sports, it isn't bad. The Tour de France burns more fuel than — just think of the Tour's huge entourage. The biggest consumption of gas is by the spectators who come to the event, but try saying to an organiser that he should sell 10 per cent fewer tickets."
