Renault have confirmed that Carlos Sainz Jr. will race alongside Nico Hulkenberg during the 2018 season following Toro Rosso's switch to Honda engines.
With Toro Rosso switching to Honda and McLaren to Renault, the French manufacturer demanded that Sainz be loaned to them for a season in exchange for terminating their engine deal early.
Red Bull duly agreed and confirmation that the Spaniard will join Renault was announced on Friday in the Singapore paddock.
"I'm very happy to be joining Renault," said Sainz. "To be a Formula 1 driver for a manufacturer team is an honour and I hope to reward Renault's faith in me with my very best performances on track.
"The trajectory of Renault is exciting and I'm proud to join at such an important time in their history. I am looking forward to working with everyone at Enstone and Viry, and driving alongside Nico Hülkenberg.
"I have worked closely with Renault in Formula 1 and previously in motorsport, so I know their motivation and capabilities.
"This is the start of a very exciting new chapter in my career. I would like to say thank you to Red Bull for all their confidence and support and for allowing me to take this opportunity.
"Last but not least, I specially want to thank all the people that work in Toro Rosso. They are a fantastic team of professionals and I wish them the best for the future."
