The Briton had contrasting results in the latest round during the Diriyah E-Prix double-header, taking a commanding win in the opening race before failing to score any points in the sequel.
Dennis was left “shocked why we were so bad” just 24 hours after a convincing victory, claiming ahead of this weekend’s race in Brazil that the issue was due to a lack of all-round grip in qualifying.
With a seven-week gap since the last round due to the cancellation of the Hyderabad E-Prix, Dennis believes the break has allowed the American team time to solve the issue.
“None of us knew what happened, but I feel like we’ve got to the bottom of that now and got an understanding,” Dennis told Autosport.
“I’m sure other surprises will come up and then we learn from them but it’s not like we’re now going to go on a winning rampage.
“But I genuinely do feel like we’ve found mistakes and built up a better knowledge of how everything works.
“We’ll just learn from our mistakes and our weaknesses and move forward.”
