Ferrari has become the first team to spend all of its power unit development tokens on an update at the Italian Grand Prix.
The Scuderia had spent 23 of its power unit tokens before the start of the season, and upgrades introduced in Russia and Canada each cost three tokens, leaving the team with just three remaining. Those final tokens have now been spent on a Monza upgrade, meaning Ferrari has none remaining for power unit development this season.
While certain areas can't be improved for performance purposes as a result, Ferrari can still update the power unit for reliability reasons.
Ferrari's upgrade follows major developments for Honda (seven tokens) and Mercedes (five tokens) at Spa-Francorchamps. Honda and Mercedes now have three and six tokens left for use this season respectively.

Renault introduced a B-spec power unit at the Monaco Grand Prix which delivered a step forward in performance, which only cost the French manufacturer three tokens at the time. Renault still has 21 tokens available to use for development as a result, with managing director Cyril Abiteboul previously stating it doesn't necessarily have to spend tokens to improve performance.
