Theissen - Car first, driver talks after

Mario Theissen has counted BMW Sauber out of any early driver speculation.

The 'silly season' seems to kick off earlier and earlier each year, but Theissen said contemplating the occupants of the Hinwil-built cars is currently a minor priority.

"Once we have a car that is capable of winning races, then we can talk start talking about the drivers again," the German said at the Circuit de Catalunya.

BMW figures at the Spanish venue also affirmed paddock speculation that the target is to have a 'double diffuser' up and running by the Turkish Grand Prix after Monaco.

Theissen admitted that an initial version of the concept did not prove its worth during recent wind tunnel testing.
