Kimi Raikkonen made his Formula One breakthrough with Sauber in 2001, with the highlights of his debut season being fourth place finishes in Austria and Canada.
The Finn moved to McLaren in 2002, clinching his first grand prix victory in Malaysia during the 2003 season. Raikkonen would eventually finish the year second in the drivers' standings behind the legendary Michael Schumacher.
Raikkonen's most successful season with McLaren came in 2005, where he claimed victory in seven of the year's 19 races. But once again he could only finish second in the world championship, with Spain's Fernando Alonso claiming the first of his back-to-back world championships.
Following a successful five season with McLaren, Raikkonen replaced Schumacher at Ferrari in 2007. The move immediately paid dividends as he claimed victory in his debut race for the team in Melbourne.
After adding to his early win in Australia with victories in France, Britain and Belgium, Raikkonen sealed Ferrari's 200th grand prix triumph in China.
The high point of Raikkonen's career-to-date arrived at the 2007 Brazilian Grand Prix, where his victory helped him clinch the world championship despite entering the race third in the drivers' standings.
Raikkonen left F1 in 2009, spending three years racing in the World Rally Championship for Tommi Makinen Racing, Citroen and his own ICE 1 team. He also tried his hand at NASCAR, taking part in the 2011 Top Gear 300 at the Charlotte Motor Speedway.
Raikonnen's return to F1 was confirmed on Wednesday, with the 32-year-old signing a two-year deal with Renault.
