Alonso put pen to paper on a multi-year deal with Aston Martin after mulling over his future options, a deal which will include driving in F1 for at least the 2025 and 2026 season.
Depending on whether Alonso will want to continue or not, that F1 deal can either be extended or converted into a non-driving role with the brand in what the Spaniard called a "lifetime project".
Alonso will turn 45 during the 2026 season and while the two-time world champion sees no signs of slowing down any time soon, he says he will be honest if he does feel he is losing any of his drive.
"It is true, I will be 45 or more and keep racing," he said. "If one day, I feel that I'm not motivated, not in good shape or not fast...I think I have a very honest relationship with Aston.
"I will be the first one to raise my hand and say: 'You know, I have maybe lost here or there' and we will find solutions.
"But I don't see that coming for the next few years. As I said in Japan, probably one of my best races ever maybe happened just five days ago, so I am feeling good. I don't see any problem there.
"And Lewis will turn 40 next year in January, so at least I will not be the only 40 plus that you will talk [about]!"
