Kimi Raikkonen was fastest at the end of an animated session with numerous incidents and spins. As incidents prevented late improvements, the Finns earlier time continued to be fastest, just a tenth ahead of Ferrari team mate Sebastian Vettel.
Even though the session was dry, earlier rain had washed the track green, meaning there was little grip yet again. Numerous drivers fell foul to that, with several overshooting their braking points at the final and first corners of the track, two sharp corners following long straights. Bottas and Hamilton were among them, with Hamilton notably doing so on his last flying lap, hence ending up in 5th, two tenths down on Bottas.
Daniel Ricciardo was just quicker than both Mercedes, going third fastest in a straightforward session for him. His own team mate, Max Verstappen, seemed to be on the way for a relatively quiet session as well, until he had a misunderstanding in the dying seconds with Jolyon Palmer. The latter, on a flying lap, appeared to understand that Verstappen was allowing him past, but when he didn't, the Renault driver hit Verstappen in the back, causing a puncture for the Red Bull driver, and some damage to his Renault's front wong. Both obviously blamed each other for the incidents via the team radio.
Force India were again well in the top 10 with Perez going 7th fastest and Ocon 9th fastest. Felipe Massa snuck in between them while Stoffel Vandoorne completed the top 10, just ahead of of his McLaren Honda team mate, Fernando Alonso.
Haas meanwhile struggled badly in FP3 as Grosjean was unable to find any pace, and ended up only marginally faster than the Sauber cars. Kevin Magnussen was even worse off, as he first sat out part of the session with an electrical problem, and when he eventually did return on track in the closing stages, an engine issue forced him to return to the pits again.
The end of the session also saw a problem occur on Sebastian Vettel's car, with the German slowly going to the pits without shifting gears.
