Ferrari have made the final changes to their power unit with confirmation that they have used their remaining three tokens ahead of the Italian GP.
On the back of Mercedes’ Belgian Grand Prix upgrade, Ferrari have responded with one of their own.
The Scuderia used three tokens, their last for this season, in order to improve the engine ahead of their home grand prix.
Both Sebastian Vettel and Kimi Raikkonen have a new ICE, turbocharger, MGU-H, energy store and control electronics for Italy.
Ferrari’s rivals still have tokens remaining; 21 for Renault, six for Mercedes and Honda have three.
