Kimi-Matias Räikkönen (Finnish pronunciation: [ˈkimi ˈmɑtiɑs ˈræikːønen]; born 17 October 1979), nicknamed "Iceman", is a Finnish racing driver currently driving in Formula One for Alfa Romeo Racing. He won the 2007 Formula One World Championship in his first season at Scuderia Ferrari. After nine seasons racing in Formula One he left the sport to compete in the World Rally Championship in 2010 and 2011, returning to Formula One from 2012. In addition to this title, Räikkönen also finished second overall in 2003 and 2005, and third in 2008, 2012 and 2018. Räikkönen has won 21 Grands Prix, making him the most successful Finnish driver in terms of Formula One race wins. He is the only driver to take a race win in the V10, V8 and the hybrid V6 engine eras.Räikkönen entered Formula One as a regular driver for Sauber-Petronas in 2001, having competed in only 23 car races previously. He joined McLaren-Mercedes in 2002, and became a title contender by finishing runner-up in the championship to Michael Schumacher in 2003, and Fernando Alonso in 2005. Räikkönen's seasons at McLaren were plagued by severe unreliability from his cars, prompting a move to Ferrari in 2007. This change saw him crowned Formula One World Drivers' Champion that season, pipping both McLaren drivers–Lewis Hamilton and Fernando Alonso–to the title by just one point. In 2008 he equalled the record for the greatest number of fastest laps in a season for the second time.
