STR still not ready

Toro RossoToro Rosso are still not ready to announce their driver line-up. Although Doornbos has now committed to Red Bull and the Champ Car series, Berger is still keeping his driver line-up under his hat – although Liuzzi and Speed are still the firm favourites. Berger will not say why he is still not prepared to announce his drivers but it is rumoured the delay is due to Sebastien Bourdais. Although Bourdais has a Champ Car contract, it is thought that Berger is still trying to negotiate for Bourdais to race in a Formula 1 car in the 2007 season.
