"We are yet to piece it altogether – Hong Kong we were fast in qualifying and obviously got a good result but the last few races we haven't been able to maximize but Santiago was a huge confidence booster for myself and the team."
Evans secured his best result of a tough season in Mexico City last year with a stunning fourth place. He hopes with a much more competitive car this year the result will be even better.
"It was definitely a bit of a one-off last year," Evans admitted. "But we were in the hunt most of the race and had a little bit of luck at the end.
"This year, on the back of a strong result in Santiago, we have learned a lot over the last few races.
"Hopefully we can hit the ground running and have a completely smooth day. We haven't had a smooth day yet.
"A podium is our goal and that is what we are working towards."
The high altitude of Mexico City will have an impact on the cars but nothing like more traditional types of motor racing like Formula 1 or the World Endurance Championship.
The electric power units aren't hampered to the same degree as combustion engines.
"The beauty of being electric you don't really get affected by the very low air density here compared to what F1 deals with," Evans said.
"Obviously you have a lot less drag, which you can't avoid. There might be a little impact on cooling as well.
"In terms of altitude it doesn't really affect us as much."
