Heidfeld uncertain about future, no KERS in Turkey

(GMM) Nick Heidfeld on Thursday admitted his future in formula one is currently insecure.

In his tenth season on the grid, the 32-year-old is still yet to achieve his maiden victory, while his team BMW-Sauber flounders in its 2009 championship effort.

German Heidfeld confirmed at the Istanbul circuit ahead of the Turkish grand prix that he does not currently have an assured contract for 2010.

"As always, at the appropriate time I will consider the relevant options that promise the most success in the future," he is quoted as saying by Deutsche Presse Agentur.

Heidfeld also told reporters that, while his car will feature a double diffuser for the first time this season in Turkey, BMW has opted against reintroducing KERS this weekend.
