Number 4. Williams
It is unlikely that Mercedes’ third and final customer team, Williams, will switch from the Silver Arrows’ power any time soon, unless Williams’ team principal, James Vowles, decides to take the team in a new direction. With three seasons to go before the power unit regulations change over, it would make sense to stick with what they know well as they aim to climb back up the grid.
However, if Honda were to re-partner with Williams, it would bring back a legendary duo in Formula 1 history. The Japanese automaker powered the team to World Championship victories in 1986 and 1987, so a reunion could bring a sense of nostalgia and excitement to the sport.
