F1: Williams set sights on overhauling Mercedes and Ferrari

Williams F1 drivers Felipe Massa and Valtteri Bottas are confident they can mount a serious challenge to Ferrari and Mercedes in 2016.

Valtteri Bottas finished fifth and Felipe Massa sixth in the standings as Williams ended the season in a comfortable third place in the constructors. Mar 12, 2016
