Cassidy entered the first of the weekend’s London E-Prix races 24 points behind Jake Dennis in the championship, with both title protagonists starting on the front row for Saturday’s race.
While Cassidy led from pole, his team-mate Buemi moved ahead of Dennis and acted a rear-gunner which allowed Cassidy to take both Attack Mode activations and remain in the lead.
Cassidy then allowed Buemi ahead in order for his team-mate to lose less time when he took his own Attack Modes, but once the order shook out the pair ran third and fourth with Buemi ahead.
The pair circulated for a full lap in tandem before Buemi went defensive into Turn 1, with Cassidy pulling alongside through the opening turns, before Buemi cut in front at Turn 4.
The resulting contact damaged Cassidy’s front wing which required a pitstop for a replacement, before the New Zealander retired after making contact with Maserati’s Edoardo Mortara as Dennis secured the title.
“I had the race won, I’d done both my attacks. I had a lot of energy. I was leading and I was just too nice,” said Cassidy.
“I gave up the lead to help him out and try and do my bit for the team. Maybe I need to be a bit selfish.
“I felt these [last] two races I’ve just been kicked in the nuts. We had all the potentially to do it [win the title] as well.
“I don’t want to take anything away from Jake, but I’ve just been kicked hard in the nuts.”
When asked if the incident was an issue to be taken up with the team or Buemi, Cassidy said: “Neither, the championship’s gone. I’m not a guy who wants to fight about something that’s in the past.”
