The driver market is in flux at the moment, following Lewis Hamilton’s decision to move to Ferrari, and the internal ructions at Red Bull caused by allegations about team principal Christian Horner’s behaviour towards a female colleague.

Alonso had spoken to other teams, he admitted. He would not name them, but it’s no secret he meant Red Bull and Mercedes.

But, as he had said he would just a few weeks ago, Alonso made his own decision in his own time, not waiting for, or being rushed, by others.

“I felt the most wanted in Aston Martin,” said Alonso. “The other conversations were just light and maybe more time was needed, whereas in Aston there was a clear desire to work together and it was the same I had.”

He said the new contract was “the longest project I ever signed – it will keep me linked with Aston for many years to come. Let’s see how long I keep driving.”

Time was when it was felt that the late 30s were as long as a driver could go before he lost his edge. Now, Alonso will still be out there in his mid-40s, something that has not happened for a top driver since five-time world champion Juan Manuel Fangio in the 1950s.

“Yes, it is true,” he added. “I will be 45 and keep racing. If one day I feel not motivated, or feel I’m not fast, or not sharp, I have a relationship with Aston very honest and I will be the first one to raise my hand and say, ‘I have maybe lost here or there’, and we will find solutions.

“I don’t see that coming for the next few years.”

As evidence, he reiterated the point he made after Sunday’s Japanese Grand Prix that it was “one of my best races ever”. And it took place five days ago.

Alonso even found time for a joke about the constant questions about his age as he added: “Lewis will have 40 years in January so maybe I will not be the only one 40-plus you will be talking about.”

The decision whether to stay in F1, he said, was more about whether he could still put up with the second-order aspects outside racing that he has never enjoyed.

“It was not the racing,” Alonso said. “Looking at the calendar, I was a little bit afraid that this would be heavy for me. There are all the commitments pre-season with the photo-shoots, car launch, all these things are quite demanding for drivers in general and. for me, in particular at this time in my career.

“So I said, ‘Let me go through that tough period as I call it, of marketing and media and things like that, and then that tough period of travelling and time zones and big plane (flights). If I feel I am not enjoying what I am doing, it is better to not keep racing. If I go through that and I love racing and all the rest is not heavy on me, I want to continue. Why not?’

“That was the first thing I wanted to clarify with myself.”

After that, Aston Martin’s relative competitiveness, its steady stream of upgrades so far this season, continuing growth as a team – with a new wind tunnel at their new factory coming on stream later this year – and the prospect of working again with Honda when the Japanese company becomes their engine partner in 2026, were enough to convince him it was the right place to be.

“My biggest concern or the bad side of driving was missing my family and not having a normal life or my own family at one point or whatever,” added Alonso. “But in this regard I said, ‘OK, let’s see year by year, month by month’.

“I spoke with my family. They will come more often to races. All of them are coming to Miami [in early May] now, my mother, my sister and my two nieces.

“We decide and plan to make some changes for the things I miss or the things that maybe worry me about keeping racing.

“F1 takes all your time. You have to give up everything in life for racing and I wanted to speak with myself to make sure I wanted to do so.

“Once I had done that, I sat with Aston and it was not too difficult. We both wanted the same, I wanted to keep racing with Aston Martin and they wanted to keep me, and when two parties want something at one point you reach an agreement.

“I am extremely excited to keep racing. I feel at home. It was also a sense of loyalty that I wanted to express to my team [who I joined] one year and half ago.

“We started together and we achieved so many things, so many highs in such a short period of time and I thought this was just the beginning.”
