Battery failure caused Rosenqvist exit


Felix Rosenqvist’s retirement from the Mexico ePrix was caused by a battery issue that Mahindra had no control over. 

Rosenqvist was in the lead of the race when his battery failed on lap 13. The Swede was able to get his car started again, but it stopped two more times which eventually led to the Mahindra’s driver retirement.

“It was one of those rare days when I can say it was quite a perfect Saturday. Right from the practice sessions through to qualifying,” said Rosenqvist. “I was out in front with a comfortable three-second lead, and it was getting better. It was all a bit too good to be true, but the issue was not in our hands. We need to move forward from here and get back to the top.

Despite failing to finish the race, Rosenqvist remains second in the drivers’ standings and only dropped seven points to championship leader Jean-Eric Vergne.

Williams Advanced Engineering produces the battery in the Formula E car for all ten teams on the grid. Therefore teams have no control over maintaining its reliability, which means any driver could suffer a battery issue at any event.

Nick Heidfeld also retired from the race with a water pump failure which meant the Indian team picked up just three points in Mexico from Rosenqvist’s pole position. Despite this Mahindra are still second in the championship, 9 points behind leaders Techeetah.
