Toro Rosso undecided on engine future

The Red Bull Junior team held a meeting in the Sakhir paddock on Thursday to discuss their long-term plans but decided to wait until there is a clearer indication about the overall performance of their V10 power-unit before making a decision.

"We had a meeting here in Bahrain but nothing is decided," Toro Rosso team principal Franz Tost told autosport.com. "We have to see now how is the progress from our side and then we will have to see how everything is. It is too early to say and we will have to wait for now."

The team have a contract to run Cosworth V10 engines in 2007, as part of a two-year deal that they inherited from Minardi.

Tost suggested that if the team were to move forwards then they might need to switch to V8s, purely because the V10 would likely become less and less competitive. The team cannot begin contemplating the design of their 2007 car until they know the exact specification of their engine.

"The engine needs to be the first decision," added Tost. "We took over the Minardi contract because firstly Red Bull respects contracts and secondly because it was the quickest way and best way to build up the car and everything.

"Whether we continue with the Cosworth V10 we don't know, because after all these discussions we have to see where we are. If next year the V8s are not limited and we have the same V10 regulation (restriction) then we don't have a chance.

"From the middle of this season I expect the V8 engines to make a great jump forward. You will see."
