Buemi hopes 'something abnormal' behind issue
Sebastien Buemi hopes his Renault e.dams team can find "something abnormal" to explain the energy management issues he encountered during last weekend's inaugural Formula E race in Rome.
Buemi ran sixth in the early stages of the race before rising to third when he followed the same pitstop strategy as eventual race winner Sam Bird.
But the 2015/16 FE champion had faded to sixth by the finish as he struggled with the energy levels in his second car.
"I felt that the car was handling well and I was only five seconds behind Bird after the first stint," Buemi said.
"But we consumed too much energy and we have to find out what didn't work.
"We haven't yet analysed the data, but I hope that we're going to find something abnormal to explain why."
Renault team boss Jean-Paul Driot explained that Buemi's battles in the pack throughout the race had hampered his energy management, and the team felt an underlying issue had made the problem worse.
"We had the same strategy as Bird but because Buemi was obliged to attack a lot with Oliver Turvey and defend with the others [early on] he consumed quite a lot more than previously planned so we couldn't do one more lap [in the first stint]," Driot told Autosport.
"And on top of that Bird was OK until the end but we had consumed quite a lot and after [the car swap] we were obliged to fight, [while] Bird was always on clear track - so it was easier.
"This is why we had some problem and we were also lacking energy - we don't understand why, so we are analysing the data.
"In Punta del Este it was working well. Here, the energy on the second car, there might be a problem because it's not normal.
"Even under the full course yellow [Mitch] Evans was coming back - so there is something wrong somewhere.
"I think we have to take it back, not from scratch, but we have to put everybody back into the right way, [to find] the right direction to be back at the top."
Driot added that had Buemi started higher up the order than his fifth place grid slot the team might have adopted a different strategy that could have left its driver more power to use later in the race.
"Buemi made a slight mistake during the superpole, but I'm glad that he was fighting for the superpole," he said.
"I don't think he would have gone over [Felix] Rosenqvist who was really quick.
"But we should have been on the front row and the race, if we had been up front, we might have changed our strategy and do one more lap like we do sometimes.
"So we would have been nearly OK on the percentage of energy remaining."
