Honda: Toro Rosso engine issues won't impact weekend

Honda F1 technical director Toyoharu Tanabe says the double-trouble that hit Toro Rosso in FP2 - with engine issues for both Pierre Gasly and Dany Kvyat - won't have a bearing on the team's Brazilian Grand Prix weekend.

Gasly's engine expired in the afternoon session, a failure that was followed shortly after by an incident that saw Kvyat veer off course and crash as the result of a sudden power unit shutdown.

Tanabe insisted however that both drivers were running high-mileage Friday units.

"Towards the end of the session, the ICE on Gasly’s car failed and then Kvyat crashed due to a complete shutdown and with the team, we are now investigating the cause of both these problems," explained the Honda engineer.

"However, they have no effect on the rest of the weekend from a PU point of view, as both of them were running 'Friday only' PUs, due to be changed tonight."

While annoyed by his engine failure as it robbed him of track time, Gasly admitted the breakdown was hardly a surprise.

"A smoky engine is never great," said the Frenchman.

"It was Friday's engine, this one had quite a lot of mileage. Already with all the races earlier in the season and the Fridays we've done.

"We knew this could happen at some point so it just blew up towards the end of the session. We lost a bit of track time and some laps on the long run.

"It's not ideal but we knew that it would happen at some point."


Kvyat said his session had been unfolding in a positive way until his forced late exit.

"We had a productive session until the moment when the car switched itself off," the Russian said.

"We now need to find out what the problem was, but until then I think it was a solid session.

"We understood the track well and the requirements needed for tomorrow to go faster, so we will work hard overnight and try to improve tomorrow."
