Ahead of the team's first race with the Japanese manufacturer, Tost has explained why Toro Rosso's new partnership has so far been unlike the relationships with its previous suppliers.
In the past, we just got a power unit and suppliers said: 'Look, this is the power unit, with the pipes, with all the aggregates, just put it into your car.' “And now our designers are sitting together with the Honda engineers, they think 'OK, how can we create the oil tank, for example, in front of the engine, how to put it in a best possible way into the chassis'.
Tost reckoned the new Honda partnership was “the first time” that his team had this much input on the engine side, and said Toro Rosso engineers relished the freedoms they had in setting up the power unit.
But Tost says it's the car the team will prepare for 2019 that he has particularly high hopes for.
