(CNN)The new Formula One season is almost upon us, and the big change is at the front of the grid.
Out goes 2016 world champion Nico Rosberg; in comes Valtteri Bottas from Williams.
The flying Finn joins Mercedes and last year’s runner-up Lewis Hamilton, who will be determined to win a fourth F1 crown this season.
But that’s not all. Though Red Bull and Ferrari have stuck with their tried and tested pairings, last year’s surprise package Force India has replaced Renault-bound Nico Hulkenberg with Esteban Ocon.
The French driver impressed at the now-defunct Manor last season and will team up with “podium pushing” Sergio Prez of Mexico.
With Bottas leaving Williams, Felipe Massa has postponed his retirement and returned to the team. His experience will be vital alongside 18-year-old rookie, Lance Stroll.
Elsewhere, McLaren has bid farewell to 2009 World Champion Jenson Button which means rising star Stoffel Vandoorne steps in alongside two-time championship winner, Fernando Alonso.
The Toro Rosso pairing of Daniil Kvyat and Carlos Sainz Jr. is unchanged, whilst American team Haas has welcomed Kevin Magnussen from Renault. The 24-year-old Dane replaces Esteban Gutirrez who has traded F1 for Formula E.
Over at Renault, Nico Hulkenberg is joined by Englishman Jolyon Palmer. Finally, Sauber welcomes Pascal Wehrlein from Manor.
