Renault e.dams’ Nico Prost has said he knew from the beginning he’d choose Formula E over the World Endurance Championship when the two series clash in July.

Unlike Renault e.dams’ team-mate Sebastien Buemi, Prost will race in New York, instead of competing in the 6 Hours of Nurburgring with Rebellion.

“For me, it’s quite an easy situation, because Rebellion is very understanding about the situation,” Prost told Read Motorsport.

“For sure, if we’re fighting for the championship in LMP2, it’s going to be a bit disappointing but, on the other hand, I think in Formula E we’re in the hunt for a good place or even the championship, so I knew from the beginning I’d do Formula E.”

At least six Formula E drivers also have WEC commitments and will have to make a decision due to the clash. The two series had a gentlemen’s agreement to avoid races on the same weekend, but the fear of an F1 clash forced the Nurburgring organisers’ hand.

With FE getting bigger every year, clashes are expected to get more common, making it difficult for drivers to compete in both series. Lucas Di Grassi, who raced in WEC last year, left the series to focus on Formula E.

“It’s getting harder and harder to do both championships,” Prost said.

When asked if he’s worried about missing the New York ePrix – a double header – Buemi said he’s “not thinking about it yet”.
