Who won the inaugural Formula E championship in the 2014–15 season?

Nelson Piquet Jr. won the inaugural Formula E championship in the 2014–15 season.

The first Formula E season began in Beijing in September 2014 and concluded in London in June 2015 after 11 races. Piquet, driving for China Racing, finished first in the drivers’ standings and became the series’ first champion. He secured the title by a narrow margin over Sébastien Buemi.

Piquet’s campaign was built around consistency and a strong late-season run. He won two races, at Long Beach and Moscow, and added several podium finishes. His title was especially notable because Formula E introduced a new electric single-seater championship with standardized first-generation cars supplied for the inaugural season.

Jean-Éric Vergne, Sébastien Buemi, and Lucas di Grassi were all important early Formula E figures, but none won that first drivers’ championship. Buemi later became a multiple champion, while di Grassi won the 2016–17 title. The answer is specific to the 2014–15 drivers’ championship, not the teams’ standings.
