Ferrari’s strict engine development plan
Ferrari is set to exploit their remaining seven development tokens in two steps and is therefore prepared to take engine penalties in Austin or Mexico.
The Italian team headed into the season by having ten development tokens remaining over the course of the season as they have only used 22 of the maximal 32 before the start of the 2015 season. In Canada they introduced important changes which mainly concentrated on the internal combustion engine.
According to the Italian publication Autosprint Ferrari are set to bolt new developments on its PU which are worth two tokens. This engine which will be the fourth both for Kimi Räikkönen and Sebastian Vettel will be introduced in Monza.
The remaining five tokens will be then used in Mexico or the USA. As both Ferrari drivers will have already used four engines out of their allocation by that, they should be set for grid penalties and therefore sent back by ten grid places if they only need to change the ICU.
Ferrari is said to have decided for this way as they wanted to exploit the in-season engine development in the best way in a bid to have the best power unit possible heading into the preparation period for the next season.
