Raikkonen, now the oldest driver on the grid, made his debut for Sauber as a highly-inexperienced 21-year-old, going on to win races for McLaren and the title for Ferrari in 2007.
His mid-contract split from Ferrari at the end of 2009 was partly acrimonious, as he left F1 altogether and enjoyed a two-year sabbatical with rallying and Nascar exploits.
Raikkonen returned to the grid with Lotus in 2012 and, with his pace intact and achieving highly consistent results, he was re-signed by Ferrari to be Fernando Alonso's teammate in 2014 and beyond.
But, now 34, he told Sport Bild: "I will not drive in formula one for ever.
"I already said in my first time at Ferrari that this will be my last team," Raikkonen smiled. "As you can see, I have kept my word."
