Lewis Hamilton once again topped the timesheets in second practice for the championship-deciding Abu Dhabi Grand Prix.
Nico Rosberg was again second, but he had closed the gap to within a tenth of a second of Hamilton's pace setting one minute 40.861 seconds lap time.
His compatriot Valtteri Bottas finished the session in seventh, ahead of the Force India duo of Sergio Perez and Nico Hulkenberg, while Felipe Massa, competing in his final Grand Prix weekend, was tenth.
Kvyat one again had his session cut short due to a left rear puncture.
