Canadian Lance Stroll turned 18 years old on Oct. 29. Five days later, he signed to race for Williams F1 in 2017. Stroll is the youngest FIA European Formula 3 champion, but word is that the Stroll family is paying Williams at least $25 million for the drive in 2017 — in addition to around $15 million spent this year to fund a discreet eight-circuit testing program for Stroll, using an unliveried 2014 Williams-Mercedes, to make sure that he knows the cars and the circuits before he makes his F1 debut.
