Vowles clearly sees something in the data and the smiley, upbeat personality that has convinced him that Colapinto can do a better job than Sargeant over the balance of this season.
He will be a breath of fresh air for the Williams camp. At Interlagos last year he was embedded in the team as part of his preparations for the Abu Dhabi rookie test, and his enthusiasm and excitement at just being part of the F1 environment was clear to see – there was no sign of the sense of entitlement that some youngsters display when they reach the top level.
“Driving the F1 car on the Tuesday after the race in Abu Dhabi, it’s going to be a very unique moment for me, very special,” he said that weekend. “Since I started racing in go-karts when I was 10 years old, my dream was one day to be able to drive an F1 car.
“And to already have that in sight and being able to have that first test, those first few laps, is something unbelievable. I was not really thinking about it, or even expecting it, when the year started.
“Williams have been so helpful this year, to be working with them so much. It’s been an amazing opportunity to be with such an historic team, with such a big legacy in motorsport, in F1. It’s one of the things that I dreamed of since I was a kid.
“And they have been super helpful, not only driving-wise, but also on the personal aspect they have been really supportive. And I’m just very proud to be part of this team. I hope to continue this journey many more years together.”
That journey hasn’t been so easy. In his mid-teens Colapinto was dispatched to Italy to further his career, and thus had to do some growing up far from home.
“Argentina is my country since I was a little kid, I lived there until I was 14 years old,” he said in Brazil. “But it almost feels like I’m still living there, all my family are still in Argentina, in Buenos Aires.
“I left when I was 14 years old only to Italy, I didn’t know Italian, I needed to wash my clothes, I started to cook for myself. These are the sacrifices that someone makes to achieve what you want in sport.
“And of course, it’s been hard, I’ve been through many challenges. And now I’m just enjoying the moment, enjoying being at the top of motor sport, that is a sport that I love.
“Then suddenly you realise I’m in F1, and it’s something insane that two years ago, I was looking at on TV, thinking it was super far away.”
It’s not been straightforward for Colapinto in terms of securing sponsorship in his home country – there’s a reason why Argentina hasn’t had an F1 driver since Gaston Mazzacane at Prost 23 years ago.
“It’s been really hard to find the budget,” he explained. “It’s very difficult for a South American. And with the sponsors, with the economic situation of Argentina, unfortunately, it’s very difficult for my home companies to support me, because the economic situation is really bad there.
