Reigning world champion Sebastien Buemi has been unbeatable so far in season three of the Formula E World Championship.

Hong Kong's towering skyline provided the backdrop to the race on the streets around the Central Harborfront. The pit lane featured a new name, with the Jaguar Racing team entering Formula E for the first time.

The race took place on October 9 in the shadow of the Two International Finance Center.

Race 1: Hong Kong —
It was the first time Formula E had raced on the streets of Hong Kong

The Formula E eVillage in Hong Kong was popular with locals.

Nelson Piquet Jr. -- the 2015 Formula E world champion -- secured pole position in the opening race. But the Brazilian (seen here at the front of the pack) couldn't maintain his advantage.

Race 2: Marrakech —
From Asia to Africa. Formula E broke new ground in Morocco in November 2016 -- the Marrakech ePrix was the all-electric series' first race on the continent.

Rosenqvist secured a superb pole in only his second race in Formula E but the Swede was eventually chased down by Buemi's Renault eDams.

Buemi continued his 100% start to the season with victory in Marrakech.

Race 3: Buenos Aires —
On to more familiar territory for Formula E in Argentina. Its capital was hosting its third ePrix in as many seasons.

Home fans gave a rapturous reception to Argentina's three-time world touring car champion Jose Maria Lopez, who joined the DS Virgin Racing team for season three.

The Puerto Madero Street Circuit is one of Formula E's wider street circuits -- offering plenty of chances to overtake.

Di Grassi started on pole for the first time in his Formula E career, but the Brazilian's old adversary Buemi claimed the checkered flag in the South American race.
