DANIEL Ricciardo will drive for the Enstone-based Renault F1 team in 2019.

The 29-year-old will leave Red Bull at the end of the year after five seasons.

Ricciardo, who has won seven grand prix, including victories in China and Monaco this year, felt it was time for a new challenge.

The Australian, who is fifth in the drivers' championship, will partner Nico Hulkenberg at Renault.

Ricciardo said: “It was probably one of the most difficult decisions to take in my career so far.

“But I thought that it was time for me to take on a fresh and new challenge.

“I realise that there is a lot ahead in order to allow Renault to reach their target of competing at the highest level.

“But I have been impressed by their progression in only two years, and I know that each time Renault has been in the sport they eventually won.

“I hope to be able to help them in this journey and contribute on and off track."

Renault sit fourth in the constructors' championship after an impressive first half of the season.

Managing director Cyril Abiteboul added: “Daniel’s signing underscores our determination to accelerate our progress towards the forefront of the sport.

"It is also a recognition of the work accomplished over the past two and a half seasons.

"Daniel’s undoubted talent and charisma are a huge bonus and statement for the team.

"We will have to repay his faith in us by delivering the best car possible.

"We welcome him to our growing team in 2019 with a great deal of pride, but also humility.”
