Sebastian Vettel will start the Singapore Grand Prix with a new MGU-H, ICE and turbocharger after Ferrari elected to make the changes in the wake of his qualifying disaster.

An issue with the anti-roll bar would see Vettel forced to try and lap the twisty street circuit with barely any front-end stability, the German forced to abandon his laps when it became apparent he wouldn't reach Q2.

Leaving him last on the grid, Ferrari have thus taken advantage of the lowly starting position by giving him fresh components for the 15th round of the season.

Additionally, Romain Grosjean will take on a new gearbox after crashing heavily in qualifying, dropping him from 15th on the grid to 20th.
