Sebastian Vettel was the fastest in the third free practice session, ahead of the duo of Mercedes. The German wants to take advantage of the penalty to Hamilton, and exit from the pole is a critical step, so they showed their cards (unlike other days from Saturday) before the classification.
The session had a serious scare Carlos Sainz to five minutes. The engine of the Toro Rosso’s Spanish stopped when faced by his first timed lap of the day, and between cries of ‘engine, engine’, he was forced to stop it.

the work of The mechanics paid off, and the spaniard was able to complete slightly more than half of the session, which enabled him to complete the planned work, despite the scare and acabaro with the 10th fastest time of the session.
To Fernando Alonso was a session a little different, as he had to devote to configure the power unit. The spaniard will take the rest of the weekend, the specification 2 of the Honda engine, and therefore was not able to shoot in optimal conditions of competitiveness. It wasn’t the 15th position in the table of times.
Nor was it an inconvenient time of the rehearsals for Lewis Hamilton. The british will lose five places on the grid this Sunday to replace the gearbox, but Mercedes will have to worry about more things, after that the front brakes left reventasen at the end of these third-party free.
