Ferrari and Honda set for engine upgrades

Both Ferrari and Honda have used engine tokens to upgrade their power-units ahead of the Canadian Grand Prix.

They are the first engine manufacturers to use any of their in-season development tokens, but this should be good news to the likes of Ferrari, Sauber and McLaren.

Ferrari have used three engine tokens, although there is no way of knowing what they have used their tokens to change at this stage.

Honda have stated that they have used two tokens and have confirmed that it was to improve reliability.

This leaves Ferrari seven remaining tokens for the rest of the season, whilst Honda also have seven remaining.

Both Mercedes and Renault are yet to use any in-season tokens, Mercedes used more tokens over the winter than other manufacturers so they also have seven remaining, whilst Renault still have twelve.

It had been assumed that as Mercedes pair Lewis Hamilton and Nico Rosberg will use new engines in Canada that they too might have brought some upgrades, but as yet Mercedes are yet to announce that they have used any tokens for engine development.
