What is the longest period between two of a driver's world championships? I know for Alonso, if he wins the championship this year, it will be six years since he won in 2006, but Lauda just beats this with seven years between 1977 and 1984.
Is there anyone who beats these two?
EDIT:
To answer my own question, here are all the current multiple champions:
1. Niki Lauda, 7 years (1977 - 1984)
2. Jack Brabham, 6 years (1960 - 1966)
=2. Graham Hill, 6 years (1962 - 1968)
4. Michael Schumacher, 5 years (1995 - 2000)
5. Alain Prost, 4 years (1989 - 1993)
=5. Nelson Piquet, 4 years (1983 - 1987)
7. Juan Manuel Fangio, 3 years (1951 - 1954)
8. Jackie Stewart, 2 years (1969 - 1971 and 1971 - 1973)
=8. Ayrton Senna, 2 years (1988 - 1990)
=8. Jim Clark, 2 years (1963 - 1965)
=8. Emerson Fittipaldi, 2 years (1972 - 1974)
12. Alberto Ascari, 1 year (1952 - 1953)
=12. Mika Hakkinen, 1 year (1998 - 1999)
=12. Fernando Alonso, 1 year (2005 - 2006)
=12. Sebastian Vettel, 1 year (2010 - 2011)
I think Alonso would be very unlucky not to win another championship, so it's likely he'll be moving up to near the top of the table. He'll be joint 2nd if he wins this year.
EDIT2:
Just for the hell of it, what would change if the former world champions on the grid were to win the championship this year:
Michael Schumacher, 8 years (2004 - 2012) (no chance of this happening though!)
Fernando Alonso, 6 years (2006 - 2012)
Kimi Raikkonen, 5 years (2007 - 2012)
Lewis Hamilton, 4 years (2008 - 2012)
Jenson Button, 3 years (2009 - 2012)
Sebastien Vettel, 1 year (2010 - 2011 and 2011 - 2012)
