Red Bull will have three drivers for the 2023 season.
He will help Red Bull with commercial activities.
He won seven grands prix in a row for the team before moving to France.
The principal of the team said it was great to have Daniel back. He is a genius and a brilliant person.
The family is excited to have him back.
Daniel will help the team with his experience and knowledge of what it takes to succeed in F1.
The whole team was something I'm sincerely appreciative of and the welcome he received was something I was happy about.
He said the ability to contribute and be surrounded by the best team in F1 was appealing.
He left Red Bull at the end of last year because he felt the team was becoming more focused on Max Verstappen.
He decided before the 2020 season started that he would leave for McLaren in 2021.
At the Eifel Grand Prix, Ricciardo scored a podium for the first time in nine years, and at the Emilia Romagna Grand Prix, he took a second place.
After joining McLaren, he won the Italian Grand Prix and led the team to its first win in nine years, but for most of the year he struggled to match the British driver.
McLaren decided they had to replace him, and ended his contract in the summer of 2022. Oscar was signed as the replacement.
The team and Ricciardo don't understand why he hasn't been performing well at McLaren. He decided not to join a team further down the grid and will return to F1 in 2024.
Red Bull paid for his debut with the HRT team in the second half of 2011 and then placed him in their second team for the 2012 season.
In his first season with Red Bull, he beat four-time champion SebastianVettel in three races to win the drivers' title.
At the last race of the season in Brazil, the relationship between Verstappen and Perez became strained.
The team wanted Verstappen to let Perez by for sixth place at the end of the race to help the Mexican's chances of second place in the drivers' championship.
Verstappen said that he had a reason for refusing and that it was related to something that happened in the past. It showed what kind of person the Dutch person was.
The tension was over Verstappen's belief that Perez crashed deliberately at the end of the Monaco Grand Prix in order to get his third place on the grid. Perez won the race
Perez said that the version of events was just speculation and people were making rumors. He apologized for the criticism he had given Verstappen.
The drivers spoke and cleared the air, according to Horner.
Senior figures within F1 have pointed out that the presence of Ricciardo in the team is a way of keeping Perez in line, as he knows Red Bull have a replacement already signed should relations with Verstappen sour again.
At last weekend's Abu Dhabi Grand Prix, when it first emerged Ricciardo would be taking on the role, Horner was asked if he could become an option longer term as a race driver.
He said no. The contract Daniel has is very specific. We have a two-year contract with Checo.
The load off the race drivers in areas such as marketing, show-car runs and events, and progress car development on the simulator would be taken care of by the addition of Daniel Ricciardo.
