Only yesterday the head of the Toro Rosso Franz Toast stressed that in the current season the team "for the seventh year in a row will use engines from Maranello, and it became known today that this year may be the last for their cooperation. The tests in Jerez Toast confirmed that in 2014 year, his team plans to move to the engines Renault
The agreement, however, has not been signed yet, but the contract with Ferrari until the end of the season and in 2014 year will come into force new regulations on motors. The intention of the Toast associated with the desire to unify the nodes with Red Bull Racing machines, in order to reduce costs.

"Nothing is decided yet," said Toast. - We are negotiating with Renault, will see how it will end. No contracts have not been signed yet, but we should as soon as possible to determine the supplier of engines. The sooner you sign an agreement with the partners, the easier it is to understand all the details, to resolve all issues.
The power plant for the season 2014 is very complex. Not so much because of the engine itself, but because of the turbine, because it's work related to the very high temperature, pneumatic, and also because of the gearbox. All these nodes must work as a unit, and for this we need as soon as possible to find out the name of our partner.
Ferrari did not say that can no longer supply us with their motors, but we want to use the same engines that Red Bull Racing. This is the goal".
