SAO PAULO (AP) — Mark Webber is at the season-ending Brazilian Grand Prix already looking forward to new challenges after Formula One.
Webber said on Thursday he's "relaxed" heading into Sunday's race at Interlagos, and was not having second thoughts about his decision to drive away from racing's top series.
The Australian admitted he will miss some aspects of F1, but was ready "personally and professionally" to end 12 seasons in F1.
There were more "negatives than positives" for him at F1, he said, so he was looking forward to a "fresh change" and a "new chapter" in his life driving for Porsche's endurance program next year.
"I think on Sunday it will be a little bit different, but it still feels like a normal race at the moment," he said. "So looking forward to Sunday in many ways, in terms of obviously pushing for a good result, but also I'm ready to stop and looking forward to the extended winter that I'll have and the new challenges around the corner."
Webber said "the fire was not quite" there anymore for him in F1, and having a difficult relationship with Red Bull teammate and four-time world champion Sebastian Vettel also didn't help.
"I wouldn't be leaving if there weren't things that I'm happy to leave behind," Webber said. "If there's more positives than negatives, then obviously I would stay. There's more negatives than positives."
Vettel said people don't have an accurate impression of his relationship with Webber and tend to forget how successful they were together.
"It has been one of the strongest pairings in Formula One," Vettel said. "Obviously we didn't have the best relationship on a personal level but I think that in terms of working professionally together both of us have tried very hard to improve the car and surely the fact that he will not be around next year will be a loss for the team, a loss for myself."
