La Williams ha svelato tramite alcuni scatti fotografici la nuova vettura disegnata per la stagione 2015 e sempre spinta dal propulsore V6 della Mercedes. Come l'anno passato le due monoposto verranno affidate a Valtteri Bottas e Felipe Massa. La scuderia aveva chiuso il Mondiale scorso in terza posizione tra i costruttori, mentre il finlandese aveva concluso quarto e il brasiliano settimo il campionato piloti.
La FW37 è molto simile al modello precedente FW36, ma il muso è stato leggermente modificato per rientrare nei nuovi regolamenti, anche se il particolare naso non è sparito del tutto come invece si pensava dovesse essere il caso. Il primo test in pista è previsto per il 1o febbraio a Jerez.
