Formula One chairman Chase Carey has accused his predecessor Bernie Ecclestone of stunting the sport's growth in the final years of his four-decade reign.
Carey, who on Friday will mark his 100th day at the helm of F1 following Liberty Media's £6.4billion takeover in January, believes Ecclestone's failure to create a long-term vision has left the sport behind its major rivals. Carey also defended Liberty's early record in which they have made very few changes to a sport which Ecclestone, 86, transformed from an amateur show into a multibillion-dollar global business.
Carey made his debut in the paddock at last September's Singapore Grand Prix before formally taking over from Ecclestone at the turn of the year. Last Sunday's race in Russia marked his fourth in charge.
"Day-to-day I find a level of frustration," Carey told Press Association Sport. "It was very much a sport that got into a habit of saying 'no' too much. I want to be saying 'yes' to a whole lot more. What is the value of having an idea if the answer to everything you want to do is 'no'? All it does is create frustration.
"There are an array of things that weren't done that needed to be done. We felt it was a sport that for the last five or six years had really not been managed to its full potential or taken advantage of what was here.
"All of us make mistakes and nobody is perfect. Bernie took a business from decades ago and sold it for eight billion dollars. He deserves all the credit in the world for what he has done. But in today's world you need to market a sport. We were not marketing the sport.
"When you have someone so identified with the sport for such a long period of time there is always going to be some degree of complexity. I will do what I think is right. Bernie's style was divide and conquer - to keep everything very close - but we want it to be a spirit of partnership in that we compete on the track.
"The teams, the promoters, Formula One and the FIA all have a shared vision of where we want the sport to go and building it in a way that is healthy for everybody."
One of Carey's first moves was to hire Ross Brawn, the British engineering mastermind behind Michael Schumacher's seven world championships at Benetton and latterly Ferrari, and also Sean Bratches, a former ESPN executive. The triumvirate have increased the sport's presence on social media by allowing teams to post short videos to their digital channels, and also called for more guests to be granted access to the exclusive paddock.
But the grand prix weekend itself remains untouched from the one which Ecclestone signed off his 40-year reign at last November in Abu Dhabi.
"It has been three months and we have been very clear that one of the things the sport has not been served well by is a continued short-term focus, and what we are going to do next week," Carey added as he defended Liberty's record.
"We care more about where the sport is going to be three years from now than three months from now. Bernie was always very focused on the short term, and our focus is on building long-term value.
"Some of the decisions that were made needed to have a better process to think through. The current engine, for example, ended up being too complicated, too expensive, and lost some of the sound that added to the mystique of the sport.
"We will do things and some things take time - you are not going to have a new engine in two months because if you tried to do that you are going to do more harm than good.
"We want to make sure we have the tools to manage the business as opposed to throwing things out there so somebody has a media story."
Press Association Sport contacted Ecclestone's representatives who were unavailable for comment.
