Sebastien Buemi says that his accident while leading the Santiago E-Prix on Saturday afternoon mirrored the brake issue that caused him to crash in Free Practice 1.
The Nissan e.dams driver led three-quarters of the race after securing the manufacturer’s maiden ABB FIA Formula E Championship pole position.
He lost the lead, and was forced to retire, in a crash at Turn 7 just after the second Full Course Yellow period came to an end.
“I’m basically disappointed because the issue was very similar to my FP1 crash,” Buemi told e-racing365.
“I’d like to say that it was not my fault and I think a software issue or something contributed to it.
“I’m really disappointed because today we deserved it, especially after the crash in FP1 where I was only a passenger as well.”
Buemi, who was under pressure from eventual winner Sam Bird at the time of his accident, described how the issue and the crumbling track surface cost him a potential win.
“I managed to stay at the front and then the asphalt basically got really worse,” he said.
“It really fell apart, and then basically because of that the line became narrower and narrower and because of the problem I had, I missed the apex because of the problem, touched the damaged asphalt and that was it.”
His last Formula E race win came in Berlin in 2017 but he believes that improvements made on the Nissan IM01 since the start of this season will soon bring a win for the new-look Nissan e.dams team.
“The good thing today is that I had really good pace in the race,” he said.
“In Riyadh I had a really bad pace, in Marrakesh, I had a much better pace and here it was frontrunning as we saw.
“We’ve made a massive step in terms of controlling the power, which gave us lots of performance and now it’s starting to pay off.
“Today we have converted it, and it would have been a first win for Nissan in a very long time but we took the pole at least.”
