Wolff makes full F1 test debut
Williams development driver Susie Wolff has made her full Formula One test debut as she tries to become the first female on the grid in almost 40 years.
The 30-year-old Briton took part in the third day of testing at Silverstone on Friday.
The in-season test is usually restricted to inexperienced drivers, but F1 regulars also took part to try out new tires after concerns about burst tires at the British Grand Prix earlier this month.
Mercedes was banned from the session after being reprimanded for holding unsanctioned testing in May.
Wolff's husband, Toto, is the motorsport director at Mercedes, but he was at the central England circuit watching his wife.
Italian driver Lella Lombardi was the last woman to race in F1, in 1975 and 1976.
