Nick Heidfeld has admitted he might be interested in working with BMW once again.
Between 2006 and last year, the German raced with the Bavarian carmaker in formula one.
At 33, he is now struggling to find a full-time cockpit for 2011, having tested with Pirelli this year and then completed the season with Sauber.
BMW is no longer in F1, but the marque is set to enter the German touring car series DTM in 2012.
“I have not finished my career in formula one, but working in the long term with BMW when they return to the DTM would be interesting,” Heidfeld admitted to Auto Bild.
BMW’s departing motor sport director Dr Mario Theissen indicated that the DTM team is seeking a driver of Heidfeld’s calibre.
“It will be important that we have a good development driver,” he admitted.
