The former Formula One champion removed the trademark white helmet and visor during an interview with show host Jeremy Clarkson after completing a record-breaking lap on the programme's track in Dunsfold Park, Surrey.
Clarkson said: "What's your real name? It's just too amazing for words!"
It has been suggested that The Stig is played by at least four professional drivers, with some claiming that up to eight people have taken on the role.
A Top Gear spokesman confirmed to The Daily Telegraph that Schumacher had driven the latest lap in a £1 million Ferrari FXX but added that the identity of The Stig at other times would remain "a mystery".
