Franz Tost has said that he is looking forward to Toro Rosso's switch to works Honda power for 2018.

McLaren have dumped the Japanese engine manufacturer after a failed three-year collaboration, switching instead to the customer Renault deal enjoyed currently by Toro Rosso.

Yet Tost, the Toro Rosso team boss, says that the Faenza-based team are actually not enjoying their current situation with Renault.

"We can't have more problems anyway, because we are changing the power unit every weekend," said the Austrian.

Indeed, Tost claims that Toro Rosso even went to great lengths to end the Renault contract, offering Carlos Sainz to the French carmaker as compensation.

"To terminate the contract we had to give something to Renault," he said.

"The compensation was Carlos and because of his speed, we are well aware that he is a big threat for us because he scored most of our points and on the other side, he is now with Renault."

However, Toro Rosso are happy with their all-new and motivated driver lineup of sportscar champion Brendon Hartley and GP2 champion Pierre Gasly.

Tost said that he is not even worried about being stuck in neutral with McLaren's rejected engine partner Honda next year.

"They have another winter time where they will have the possibility to sort out the problems that they have currently," he said.

"As Toro Rosso, we are the only team that will be working together with them which I think will become a big advantage.

"All the meetings we have had so far are quite promising.

"I'm more than convinced that this power unit will help Toro Rosso next year to become a very strong and competitive team."

Toro Rosso are sixth in the constructors' championship with two races of 2017 to go.
