Tost: Red Bull will win races with Honda in 2019

Toro Rosso boss Franz Tost believes Red Bull Racing will win races in 2019 with its new engine supplier Honda.

Tost's Toro Rosso side was powered by the Japanese manufacturer last season and the progress was enough for Red Bull to be persuaded.

His views of Honda also played a massive part in Red Bull's decision to switch from Renault to a brand new partnership.

"All the expectations I put into them, they delivered," said Tost to Autosport.

Toro Rosso were sacrificed a lot last season, taking grid penalties multiple times so Red Bull could have a better shot at it in 2019.

Tost is confident it won't be a similar story this time around, though.

"In 2018 we knew from the very beginning that it is a development process which we have to go through and this is what we did," Tost continued.
