SAUBER driver Kimi Raikkonen (left) must feel his world is now upside down as he takes a ride in a plane over Melbourne's Albert Park, venue of this weekend's Australian Grand Prix.

The 21-year-old Finn's world is about to undergo a dramatic change as he makes his Formula One debut on Sunday, one of four new faces to do so.

Of the quartet, he can expect the most scrutiny because many feel he should not have been granted a super licence to compete in F1.

He has competed in just 23 single-seater races and has never driven in Formula 3000 or Formula Three, the traditional 'routes' to Formula One.
