Yas Marina

The fastest part of the lap, running under the Viceroy hotel — long sweeping corners feeding the long back straight.

The hardpoint of the circuit — Turn 5, Turn 6 and the marina hairpin complex — chicanes and heavy braking.

The flowing marina section past the yacht basin and through the final corner onto the pit straight — sleek and stylish.

Going into the finale third in points, Sebastian Vettel took pole, won the race, and inherited his first world title as Webber, Alonso and Hamilton fell out of contention. Ferrari's strategic mistake on Alonso defined the race.

Leading the race with the title slipping away, Hamilton deliberately drove slowly to back Rosberg into the chasing pack. Mercedes' team radio orders to speed up and Hamilton's refusal became one of the great team-management dramas.

A late safety car, a controversial unlapping decision, and Max Verstappen on fresh softs vs Lewis Hamilton on old hards produced the most disputed race-decision in F1 history. Verstappen took the title on the final lap.
