Some reports are suggesting that, he could be heading to Williams next season, others claim he’ll be leaving F1 and swapping to the IndyCar series.
“Negotiations are ongoing and they are going very well,” the American told reporters at the Italian Grand Prix.
“But you’ve got to have a Plan B and C in the event you don’t reach an agreement. And we’ve got those plans.”
Renault F1 bosses were seen entering the McLaren motorhome at Monza on Friday, increasing speculation that a deal was being struck, although Brown made light of the situation.
“They have my Lotus 98T engine that I’m waiting for them to rebuild, so I was asking about that,” he said. “They do have it, that’s a fact.” He would not comment on any talks with Honda.
Some media reports have indicated that Toro Rosso need a decision this weekend but Brown said that was not the case for McLaren.
“Nothing’s finalised,” he said. “We don’t have to make a decision this weekend. I can’t speak for Toro Rosso.”
Brown said the decision would be a sporting one primarily with McLaren, who last won a race in 2012, needing to be back on the podium. He did not rule out Honda raising their game in time for next season.
“They’re spending more money, so they’re doing what it takes to be more competitive. They’re doing different stuff now… they’ve acknowledged they are working with some outside consultants,” he said.
“We are going to sit down next week with guys that are much smarter on power units than myself and take a view on what we see their plans are and what they’ve accomplished and then take a view,” added Brown
