Lewis Hamilton has cranked up the pressure on F1 world title rival Nico Rosberg by narrowly holding top spot in FP2 ahead of the Abu Dhabi Grand Prix.

The defending F1 world champion has taken a clean sweep of Friday practice sessions but saw his fastest lap time advantage trimmed to just 0.079s by Rosberg, with the German taking a 12 point lead into the season finale.

With Hamilton knowing he must win and hope Rosberg finishes off the podium to take the world title, attention turned to the race runs produced by Ferrari and Red Bull to see how close they could challenge Mercedes at the Yas Marina Circuit.

Both Red Bulls impressed early in long stints before struggling with tyre wear while Ferrari kept pace with the Milton Keynes-based squad.

Sebastian Vettel finished FP2 third on the timesheet a quarter of a second off leader Hamilton but missed the final 10 minutes of the session due to a broken gearbox.

Max Verstappen and Daniel Ricciardo slotted between the two Ferrari cars with Kimi Raikkonen sixth while Bottas led Williams' charge against Force India's Sergio Perez and Nico Hulkenberg.

Felipe Massa, celebrating his 250th and final F1 race before his retirement, rounded out the top ten as McLaren duo Fernando Alonso and Jenson Button slotted into 11th and 12th respectively.

On his last outing for Haas Esteban Gutierrez edged Romain Grosjean after the French driver continued to suffer with braking issues which have plagued him all season.

Jolyon Palmer led the running at the back of the field ahead of Manor pair Esteban Ocon and Pascal Wehrlein, who will be desperately hunting a top ten to get back ahead of Sauber in the F1 world constructors' championship.

It was another nightmare session for Daniil Kvyat who could only complete three-and-a-half laps until a second straight left-rear tyre puncture. His issue meant it was unsafe for either Toro Rosso to continue, hampering Carlos Sainz's session, with a broken left wheel rim.
