Mario Theissen has confirmed that BMW-Sauber's major aerodynamic upgrade for the Spanish grand prix does not include a so-called 'double diffuser'.

We reported recently that the Hinwil based marque's first effort in the concept did not suit the F1.09 package.

"In hindsight it would have been better if we had started on this (diffuser) subject earlier," the BMW motor sport director told the German press in Munich on Tuesday.

"We are working on it, but you don't want to change too much at one time," he added, also pointing out that Sebastian Vettel is a title contender even without a double diffuser on his Red Bull.

Brawn, Williams and Toyota began the season with the controversial solution, and were subsequently followed recently by the McLaren, Renault and Force India teams.

Ferrari will roll out an initial version of the double diffuser this weekend in Barcelona, while Renault's R29 will feature its second iteration of the concept.

Red Bull is targeting the Monaco grand prix later this month for its diffuser debut.
