Raikkonen, a former F1 world champion, left the series after the 2009 season to pursue a drive in a World Rally Championship car. He's seen little success in the largely off-road series, but has, by all appearances, enjoyed his time there immensely.
According to the sport10.at and plaza.fi websites that broke the news, Raikkonen's visit was only for "personal reasons," but the factory tour has nevertheless sparked talk of his potential return to the top tier of road racing.
Williams' current drivers, Pastor Maldonado and Rubens Barrichello, haven't delivered the best results for the team this season. Maldonado's seat appears to be secure, but Barrichello hasn't yet inked a deal for 2012, potentially leaving the door open for Raikkonen should he wish to drop WRC.
We're not sure Raikkonen will want to trade his gravel tires in for Pirelli F1 slicks even if the opportunity arises, especially after having made a fairly successful NASCAR Nationwide debut this year, but we'll keep our ears to the ground.
