The 18-year-old son of former F1 world champion John Surtees has died after an accident during a Formula Two race.
Henry Surtees was knocked unconscious during the race at the Brands Hatch circuit in Kent, south of London, and was airlifted to hospital with head injuries.
A statement from the Formula Two championship said Surtees was struck on the head by a wheel and tyre from another car which had hit the tyre wall ahead of him. He was knocked unconscious and his car collided with the barriers.
Surtees secured a drive in F2 following a breakthrough year in 2008 that saw him contest the Formula Renault UK Championship and Winter Series and also make his debut in British Formula Three.
His father John is famously the only man to win world championships on two and four wheels, having claimed multiple 500cc motorcycle world championships before winning the F1 crown with Ferrari in 1964.
