Esteban Gutierrez will replace Ma Qing Hua at Techeetah for the remainder of the season.
The Mexican will make his Formula E debut at his home race at Mexico City on April 1 alongside Jean-Eric Vergne.
Gutierrez announced he would be racing in the all-electric series in January, but did not say when he would be racing or who for.
He was expected to take Loic Duval’s place at Dragon Racing for the Paris and Brussel’s rounds as the Frenchman has DTM commitments with Audi.
Places at Renault eDAMS and DS Virgin were also reportedly explored as the Mexico round takes place the day after Toyota’s World Endurance Championship team launch at Monza, which Sebastien Buemi and Jose Maria Lopez would both be attending.
However, both teams have confirmed that their drivers will be hurried to Mexico shortly afterwards for the Formula E race.
Gutierrez’s door opened at Techeetah as they have side-lined Ma after a series of disappointing performances.
The Chinese driver made his debut at the Paris ePrix last season, when the team was still known as Team Aguri, and failed to score points in the four races he competed.
He is also yet to score points in the current season, despite Techeetah using the Renault powertrain. The two Jaguar drivers, Mitch Evans and Adam Carroll, are the only other drivers yet to score points this season.
It is understood that Gutierrez has completed a deal with Techeetah and has visited their simulator in Monaco. It is not yet known if he will be able to test the car before his debut.
Official confirmation of Gutierrez’s arrival at Techeetah is expected shortly.
