Sebastien Buemi will terminate his Formula E driving contract at the conclusion of the 2026‑27 season to devote his efforts to Toyota Gazoo Racing in the World Endurance Championship.
Buemi’s Exit from Formula E
Envision Racing announced that Buemi will leave Formula E after this weekend’s London E‑Prix. Instead, he will serve in an advisory and development capacity for the team.
Buemi had been a core driver from the series’ inception, balancing the all‑electric grid with a full‑time WEC seat. The decision follows a year of discussions between the driver, the team and the Japanese manufacturer.
Schedule Storms Between Series
Formula E will run 13 calendar weeks in 2027, with Gen 4 vehicles demanding many more testing sessions. The WEC will add a ninth event, expanding a holiday‑packed summer.
Only one clash remains between the championships, when the Shanghai E‑Prix clashes with the Sao Paulo 6‑Hours. Earlier, Envision had shifted the Monaco round two weeks earlier to remove a double‑header against Spa.
Buemi explained that the overlapping commitments — two extra Formula E races, an additional WEC round at Silverstone and the new Gen 4 development schedule — would make dual participation unfeasible.
Contract Priorities and Team Dynamics
Buemi’s contract gave Toyota priority over his Envision duties, a status which evolved from full WEC commitment to a hybrid schedule and back again. The driver affirmed that Toyota’s positioning “closed the door” to pursuing both series simultaneously.
He described the exit as a “joint decision” generated by analyzing simulator preparation feasibility and the demands of test days. Buemi cited personal factors, including a family with three children, as part of the final assessment.
Upcoming Calendar Clash
Beyond the single 2027 clash, the calendars reveal several periods of heavy scheduling. For instance, the 2026 December Jeddah E‑Prix invokes a single‑series weekend but still keeps the driver in the desert for testing before the 2027 WEC series starts in March.
The 2027 schedule pushes a dense cluster of Motorsport events, with Le Mans 24‑Hours and Istanbul at Le Mans late spring, followed by a Shanghai‑Sao Paulo overlap in July.
Buemi’s advisory role with Envision will enable the team to remain competitive in the Gen 4 era while he concentrates on Toyota’s endurance machinery.
As Buemi redirects his focus to the WEC, his departure highlights the growing logistical and developmental pressures placed on drivers competing across multiple high‑level racing series in the Gen 4 era.
