Coletti wins, Vandoorne seals second

A quick start from Coletti drew him past poleman Arthur Pic on the outside of Turn 1, and the Monagasque maintained the position comfortably to the end.

The race's main point of interest came from the battle between Sauber F1-bound Felipe Nasr and Vandoorne to be second in the standings.

Vandoorne went into the race ahead by nine points, but Nasr looked to have the early advantage as he charged from fifth to second on the opening lap.

With the Belgian stuck in seventh for most of the race, unable to get past Mitch Evans in front, the final laps became all about who could set the fastest lap for the additional two points.

Nasr was quick and maintained second on-track with ease but Vandoorne set the fastest lap in the closing stages, and then took sixth as Johnny Cecotto fell back to secure second in the championship with 227 points to Nasr's 224.

Already-confirmed champion Palmer went out on opening lap after a spin in the braking zone of Turn 8, the Briton stalling after nearly collecting the back of Evans.

Pic finished in third ahead of Stephane Richelmi, Evans in fifth and Vandoorne in sixth. Cecotto and Ferrari F1 protege Raffaele Marciello completed the points.
