Nine corners at the Sepang circuit have been renovated ahead of this weekend's Malaysian Grand Prix, which organisers promise will provide a new challenge for drivers.

Malaysia's race dropped to the lower end of the calendar for 2016 after several years as one of the opening rounds. Extensive work has been conducted on the circuit in that extra time -- as well as being resurfaced, the organisers have updated drainage and run-off areas.

The most radical changes have been at the final hairpin, Turn 15. The video below shows the work conducted at the corner, which has been raised by one metre to change the racing line and potential increase overtaking opportunities.

Turns 2, 3, 4, 5, 6, 9 and 12 have also had their gradients altered. The resurfacing will have taken away a lot of the bumps that were common on the runs down to Turns 1 and 4.

Speaking of the renovations, FIA race director Charlie Whiting said: "The entire track surface and the fast lane of the pits have been resurfaced to very high standards. In a number of locations the levels of the track have been re-profiled to make the corners flow better or to improve drainage.

"This is high quality work. The works carried out to the circuit appeared excellent. The general condition of the installations was first class."

Circuit CEO Razlan Razali said "it will be as if [drivers] have come to Sepang circuit for the first time" because the changes have been so significant.
