David Coulthard has not yet signed to race in the German touring car series DTM in 2010, according to Mercedes’ Norbert Haug.
The Scot tested one of the German marque’s cars recently, sparking rumours that he will soon test again prior to replacing Mathias Lauda, the son of the triple world champion Niki Lauda.
"There is no contract signed, it is only speculation," Mercedes’ Haug is quoted as saying by the Belgian website autosportnieuws.be.
