As on the Mercedes and the Red Bull, the gearbox on Ferrari’s SF70H is made in two pieces. Mercedes reintroduced this sophisticated layout in 2013, with a titanium gear case to contain the ratios and then a second carbonfibre casing around the box, to which the rear suspension is attached.
This allows for modifications to the suspension pick-up points without a costly gearbox change. In Malaysia, it was only this casing that was damaged on Vettel’s car – and the team could change this without penalty.
The concept of applying a second carbon skin to the titanium gearbox was originally introduced by Ferrari in 2004, but at that time was done purely to make the case stiffer. On their 2017 car – as on Mercedes’ and Red Bull’s – the aim is to have two separate structures, allowing changes to the external one without being penalised for a gearbox change.
