The morning after the Australian sent F1 into its summer break with one of the biggest stories of the year, Ricciardo took to social media.
"By far the toughest decision I've made in my racing career - but 29 years living on this Earth, it was actually one of the toughest life decisions I've made".
The Australian will partner Nico Hulkenberg at Renault.
At this point in time, the smart money will be on Gasly to partner Verstappen next year, however Ricciardo-to-Renault proved that where "the smart money" goes is not always a fair dinkum indication of what will really happen.
Renault's first F1 season was nominally 1977, although they only had one driver, Jean-Pierre Jabouille, and he only entered five races, without finishing a single one. 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.
Renault released a statement that appeared to confirm that Sainz would be making way for Ricciardo.
This may not be the dream switch to Ferrari, but a move to Renault could be just what Ricciardo needs. Following his Red bull departure and move to Renault, he has posted a thank you message to Red Bull on Twitter with videos of his highlights. Ricciardo added: "I hope to be able to help them in this journey".
An fantastic journey needs an equally impressive vehicle to complement it, and they don't come much more incredible than the Red Bull RB7.
There was speculation that Ricciardo did not get the assurances he craved from Red Bull owner Dietrich Mateschitz, wrote British newspaper the Daily Mail.
For the past several seasons, Formula 1 has been dominated by three superteams - Mercedes, Ferrari and Red Bull - which have combined to win every single race dating back to the second race of the 2013 season.
DANIEL Ricciardo has shocked Red Bull by telling them he's leaving at the end of the season.
At Haas, one of two Ferrari "satellite" teams, the likely pairing for 2019 is current driver Jan Magnussen with Charles Leclerc, who will be promoted from Alfa Romeo-Sauber on the way to an eventual drive at Ferrari. "We've got nine races left to kick some ass, so let's get it". "Renault chose to come back to Formula One to fight for world championships", said team president Jerome Stoll as the deal was announced.
