Kubica race seat to be confirmed on Thursday

Robert Kubica's DTM race seat looks set to be announced on Thursday.

The well-connected Polish source Powrot Roberta claims that despite BMW's works DTM concern having overlooked the former Williams driver, Kubica will instead race a BMW-prepared private car in the German touring car series.

35-year-old Kubica, who will also be Alfa Romeo's reserve driver in Formula 1 this year, will be backed in both F1 and DTM by PKN Orlen.

The source said the DTM announcement will be made on Thursday at a press conference attended by the Polish oil company's president Daniel Obajtek.
