Formula One legend Michael Schumacher was on Sunday unveiled as "the Stig", the mystery man who test drives cars on British cult motoring show Top Gear.

The identity of the white-clad driver is kept a closely guarded secret, but Schumacher, who was Formula One world drivers' champion seven times, finally revealed himself in the first of a new series of the show on Sunday night.

Presenter Jeremy Clarkson pretended not to recognise him at first, asking him what he used to do before he became famous as the Stig, but then excitedly shouted to the studio audience: "It's Michael Schumacher!"

Former Formula One driver Perry McCarthy was Top Gear's original Stig, who dressed all in black during the first two series.
