"Every single lap I was thinking something might happen. When I got on that back straight I am petrified."

Lewis Hamilton feared another engine failure would cost him what may yet turn out to be a crucial victory in America on Sunday.

The world champion has reduced the deficit in the title race to Nico Rosberg by virtue of recording his 50th career victory in Sunday's United States Grand Prix.
