Renault at a loss to explain Prost wing failure

Renault eDAMS chief Jean Paul-Driot admitted the team was perplexed by the rear wing failure that ended Nicolas Prost's challenge in the first race of the new Formula E season in Beijing.

Prost had been running third during the curtain-raising Beijing ePrix close to the tail of second place man Lucas di Grassi, only for his rear wing to suddenly partially collapse.

Although his pace wasn't badly affected, Prost was shown the black-and-orange flag for safety reasons, forcing his retirement from the race.

“We are not happy about what happened to Nicolas in the race,” Driot told Motorsport.com. “We had the same issue here at Beijing with Buemi last year. It looks very similar to that.

"We then had a procedure in place to cure it, but we don’t know right now why [the rear wing] went. The rear wheel bumper went first and after that the wing came down.

"We could have carried on, as it was not moving so much but we got the orange flag and that was it for us as you can’t take big risks."

No reliability issues a relief

While Prost ended the Beijing race with zero points on the board, teammate Sebastien Buemi cruised to a dominant win from pole position, and Driot felt the victory showed that Renault’s single motor powertrain solution performed beyond expectations.

“Efficiency wise we are very happy and we hit all targets,” Driot said. "We have had no reliability issues and that is good because it was a big question mark with all the new equipment.

"We are satisfied with the performance as you have to say the win, pole and fastest lap by such a margin is a big reward for the big push from Renault and the whole team we have around us.

“Overall, we are highly satisfied with the performance of the new powertrain, but Malaysia will be a big test with the temperature, there will be additional question marks."

OPINION: The 2021 Formula E campaign was one without a narrative for much of the season, with no single car or driver able to break away from the pack. That makes choosing a top 10 especially difficult, particularly as the qualifying format meant some worthy performers were unable to enjoy their day in the sun.

When Nyck de Vries dominated the first race of what would be the most controversial and unpredictable Formula E season to date, it looked as though Mercedes was in for a cakewalk. But as the campaign wore on, the path to a title double became increasingly rocky. Neither driver or team would be assured of the crown until the closing stages of the very final race on a weekend of struggle in Berlin.
