• Sergio Perez, Romain Grosjean and Kevin Magnussen will leave Formula 1 at the end of 2020.
• Sebastian Vettel's time at Ferrari comes to an end as he is replaced by McLaren driver Carlos Sainz.
• Daniil Kvyat's future is uncertain because AlphaTauri has not confirmed who Pierre Gasly's teammate will be.
Sunday's Abu Dhabi Grand Prix is expected to be an emotional race for at least three drivers as their time in the sport comes to an end.
Racing Point's Sergio Perez, who won his maiden GP in Bahrain last weekend after 190 starts, will step aside after seven years at the team.
The Mexican has been linked with a Red Bull seat, but nothing has been confirmed by the energy drink team.
Perez threw a spanner in the works when he told Sky Sports he planned to return in 2022 if he wasn't able to secure a seat for next season. But he was tight-lipped on which teams he was talking to.
Checo's exit from the sport is a big loss.
The Haas duo of Romain Grosjean and Kevin Magnussen learnt their fate a few weeks ago.
Grosjean missed the last two races after his hands were burnt in a dramatic crash at the Bahrain GP.
Magnussen will race for Chip Ganassi Racing in the IMSA SportsCar Championship next season. The Dane is unlikely to return to the sport. He garnered 158 points and one podium in his career.
The Russian driver is unlikely to partner Pierre Gasly for AlphaTauri next season, although there is no confirmation from the team. F2 rookie Yuki Tsunoda has been strongly linked with the team and this is likely to see Kvyat lose his spot.
The 31-year-old is now considered a veteran in the sport as he joins McLaren for 2021 - his fifth F1 team.
The Australian will be pushed all the way by the younger Lando Norris after spending two seasons at Renault - and it's a partnership many are looking forward to seeing grow.
The four-time world champion will look back at his time at Ferrari as a disappointment because he failed to add to his drivers' titles.
Many people looked forward to the Lewis Hamilton and Vettel battle, but it was a one-sided affair that saw Ferrari move onto Carlos Sainz for 2022.
Vettel will replace Perez at Racing Point, and what will eventually become Aston Martin Racing next season.
