The Williams FW38 was a car designed by Williams for the 2016 Formula One season. It was driven by Felipe Massa and Valtteri Bottas. In Canada, Bottas secured Williams' first and only podium finish of the 2016 season, repeating his 3rd place result from last year's race. Before the Italian Grand Prix, Massa announced his retirement from racing, ending his Formula One career after 15 years in the sport. The chassis he used at the Brazilian Grand Prix was given to him as a retirement gift, though he was allowed to keep it after Williams confirmed he was returning to the team for the 2017 season.
