Schumacher – Heidfeld swap?

UPDATE (GMM) Toyota's Ralf Schumacher has again refused to rule out speculation that he and BMW-Sauber counterpart Nick Heidfeld could swap formula one seats in 2008.

''Until and including 2007 I am under contract to Toyota,'' said the German, ''and I am concentrating on that.

''After that we will see.''

08/25/06 The latest rumor in F1 circles is that Ralf Schumacher and Nick Heidfeld could swap race seats in 2008, or even as soon as next season.

The 'Express' publication reports that Toyota's Schumacher, 30, is in talks about racing for the German marque at the end of his current contract. Schumacher drove for BMW-powered Williams between 2000-2004.

''I will fulfill my Toyota contract in 2007,'' Ralf reportedly responded, while Heidfeld's manager, Werner Heinz, admitted that he had heard the rumor that his charge could fill the seat in a direct Toyota-BMW swap.
