Williams FW37 current version Unknown

One of the bedrocks of Williams' resurgent 2014 campaign was a trouble-free pre-season, and the Grove-based team made a similarly strong start in Jerez. Between them Valtteri Bottas and Felipe Massa completed 278 laps, and though they never cracked the top end of the timing sheets, there was a clear sense that Williams, like rivals Mercedes, were keeping their powder dry. Williams are being understandably coy about their chances in 2015, but chief test and support engineer Rod Nelson admitted the team were very happy with the evolutionary FW37's first runs in Spain, describing the new car as a reliable package that is straight forward to work with.
