DS Techeetah completed its first day of on-track testing with its Season Six powertrain late last month.
Jean-Eric Vergne conducted a day of running at Calafat as the team begins its private track testing phase for the 2019-20 campaign.
Teams are allowed 15 days of manufacturer testing between Jan. 1 and Oct. 1 for their new powertrains.
However, many of the teams use some days for testing aspects of their current packages, particularly focusing on vehicle dynamic and software work in the early phases of overlapping race and test programs.
Reigning Formula E champion Vergne admitted that DS Techeetah took advantage of working through several programs on the back of recent disappointing performances.
The team is understood to be investigating the possibility of temperature-related issues which have seen inconsistencies throughout the season so far.
“The car is quite hard to understand at the moment so we are working hard but we changed a lot of things in the car and we had the same feeling more or less in Mexico,” Vergne told e-racing365.
“There is something clearly missing for sure, so we are working hard to understand it more so we don’t go on being lost at race weekends.”
Vergne’s Mexico City E-Prix was compromised by contact from Nelson Piquet Jr. and Mitch Evans.
Despite being quickest in the post-Mexico test day, Vergne says that irrespective of the incidents in the race, he was frustrated by the unpredictability of his DS E-Tense FE19.
“We are limited with the testing, we know this, so we have to make the most of the times we can run,” he said.
50th Race an “Important Milestone”
The 50th ever Formula E race in Hong Kong this weekend is a significant moment in the history of Formula E, according to Vergne.
The five-time E-Prix winner joined the series at the third ever event at Punta del Este in December 2014 after his contract wasn’t renewed at the Toro Rosso Formula 1 team.
“What we have today is a completely more professional environment compared to when I arrived in Punta (del Este) in 2014,” said Vergne.
“We still have a lot of the same drivers, circuits and same fun on the track but the circus has become a lot bigger and we have more fans and media.
“It is like a young start-up company that is getting bigger and bigger and maturing every year, so it is great to see and be on the journey since more or less the start.
“In the fiftieth race this weekend you have to give Alejandro [Agag] and his team huge credit for this in every way because it is an important milestone.”
