The team had confirmed at last month’s Singapore GP that the Spaniard would be replacing Jolyon Palmer for the 2018 season.
However then came the decision to draft in Sainz for the remainder of 2017, starting at the Circuit of the Americas in Austin where Renault will have been hoping to close on Williams for fifth in F1’s Constructors’ standings.
Sainz’s signing for Renault in F1 incidentally comes seven years after he raced in the Formula Renault single-seater category in the UK (see photo).
He said: I’m very excited to be joining the team and I hope to hit the ground running. We have some hard work ahead of us going into Austin with lots of things to learn and many people to meet. I’m going to give everything to be on the pace as soon as possible even though I know it can take a bit of time to adapt, but I’m confident we can do it.”
Sainz said getting started early with Renault would help him and the team get ahead in their preparations for the 2018 season…
He added: “It’s key to have this immediate taste with Renault and get to know the people and the car. It’s a big challenge, but it motivates me.
“We have this last push for the season and I have to find where the limit of the car is, get used to the steering wheel, things like that. That’s the procedure and I will embrace the challenge.
“It’s good to see the people at Enstone putting the work in to get back to the top. They can be sure all the effort being put in is being matched on my side of things and I will be pushing flat out to help the team.”
Sainz would be going into the US GP ninth in the drivers’ standings, just one place ahead of new team-mate Nico Hülkenberg.
He continued: “We are very close together in the championship, but we haven’t had too many on-track battles.
“I’m really looking forward to working with Nico. I think he is a great driver and one of the most talented on the grid. He has lots of experience in Formula 1 so I will learn from him as soon as I can. Hopefully we can both help the team move further up in the championship before the end of the season.”
