DS Virgin Racing say they are determined to prove the true pace of their DSV-02 racer after a disappointing season so far.
The British team are languishing in sixth in the constructor’s championship, with Sam Bird’s second place in Marrakesh the only bright point.
However the team are confident that there is more to come from their package in Mexico, and point to both drivers toping the timesheets in practice at Buenos Aires as cause for optimism.
Bird said he was looking to put the disappointment of Argentina behind him and get back on the podium.
“I’m going into Mexico with a positive attitude after a difficult race in Buenos Aires.”
“I believe in the team and in the car they have put underneath me and if we get qualifying right there’s podiums to be had.”
Jose-Maria Lopez fought through the field last time out to gain a point, and believed this showed that he was getting more to grips with the car.
He won’t have the ideal preparation for the race though, as WEC testing duties will mean he only arrives in the early hours of race day.
“It will be a little challenging to be arriving in the early hours of raceday,” he said.
“But I’ve been doing a lot of work in the simulator in the build up to this race, and after fighting through the field in Buenos Aires to score another point in Formula E, I’m getting more and more comfortable with the car.”
Lopez is currently sixteenth in the driver’s standings on two points, with Bird in sixth but 57 points back from leader Sebastien Buemi.
