I can confirm that there will be NO F1 team from Prodrive. It has a lot to do with the £300K limit if the team are run be a car manufacturer, however that idea will not go ahead for next year it meant that there was not enough time to develop a car left.
I heard it the other day and I can confirm that they are designing a prototype for LM, the Vantage is aimed at competing as a GT2 Car aswell.
