Germany's Sebastian Vettel became Formula One's youngest double world champion at the Japanese Grand Prix on Sunday.
The following are some key facts about the Red Bull driver:
BEGINNINGS
-- Vettel was born in Heppenheim, a town surrounded by vineyards between Heidelberg and Darmstadt, on July 3, 1987.
-- He started out racing karts at the age of eight and then competed in junior series, including the 2004 German Formula BMW championship where he won 18 of the 20 races. That earned him a test in a Williams-BMW F1 car.
-- The following year he was top rookie in the Formula Three Euroseries, won by Britain's Lewis Hamilton.
FORMULA ONE
-- Vettel became the youngest driver to take part in a grand prix weekend when he drove for BMW-Sauber in Friday practice in Turkey in 2006 aged 19 and 53 days.

-- He took part in seven races in 2007 with Toro Rosso.
-- The German was handed a full race seat with Toro Rosso for 2008 and failed to finish his first four races. He then won the Italian Grand Prix at Monza from pole position.

RED BULL
-- Vettel switched to Red Bull for 2009 after Britain's David Coulthard retired.
-- He won four races in 2009, including Red Bull's first victory at the Chinese Grand Prix where he also secured the team's first pole position and led their first one-two finish. Vettel ended up overall runner-up behind Brawn's Jenson Button.

CHANGE

-- He was only Germany's second F1 world champion, after seven times champion Michael Schumacher.

PERSONAL
