Henry Surtees, the 18-year-old son of 1964 world champion John Surtees, died after an accident in the Formula Two race at Brands Hatch on Sunday.
The Briton, who finished the previous day's F2 race in third position, was struck on the head by the flying rear wheel of a competitor's car following a crash.
Surtees lost consciousness immediately and crashed into the barriers at the next corner without lifting his foot off the throttle.
After being stabilised trackside and at the Kent circuit's medical centre, he was airlifted by helicopter to the Royal London Hospital where he later died.
A hospital spokesman confirmed the death.
His father John Surtees, 75, won six grands prix and was also a motorcycle world champion and formula one constructor.
