- 3 tokens have been spent on ICE (combustion chamber)
- new ICE spec is sightly better than Mercedes one
- Mercedes is still ahead in the hybrid part of the PU, especially in harvesting energy
- This ICE spec was initially planned for Austria or Silverstone, but delayed due to reliability issues
- This spec is still running on benches, but was validated anyway
- New Shell fuel will be used (not written in this article, but somewhere else on the same site)
- Due to reliability issues it had Ferrari won't be using full power, but will only use an increase of 5-10 HP.
So it looks like that more power can be unlocked than those 5-10 HP gained, but in the article there isn't written how much.
