Felix Rosenqvist could contest a twin campaign between the ABB FIA Formula E Championship and the Verizon IndyCar Series in 2019.
A complex deal is believed to have been in discussion for a number of weeks to work out how the three-time Formula E race-winner could appear in both series.
The 27-year-old has been widely reported to have signed an IndyCar contract and e-racing365 understands that confirmation of his deal is set to be made public shortly.
The discussions between Mahindra Racing and his new IndyCar team are believed to center around the Swede competing in the opening three Formula E races of the 2018-19 season before he begins his IndyCar career.
He would then appear at non-clashing events through the rest of the Formula E season.
Conflicts between the two series’ schedules could see him missing the Formula E races in Hong Kong, Rome, Berlin, Switzerland and the New York City finale.
Mahindra is currently looking at the possibility of splitting the seat with a second driver subbing at the races Rosenqvist cannot attend.
Nick Heidfeld, who drove for the Indian team in Season Four, is believed to have discussed filling in for Rosenqvist at the clashing events in addition to a role as reserve and development driver.
The German told e-racing365 in July that he was looking at alternative challenges away from a full-time drive in the championship but is believed to have reconsidered when the seat-share possibility arose.
E-racing365 revealed last week that Jerome d’Ambrosio is set to join the team in the seat vacated by Heidfeld.
The Belgian will undertake more testing with the team in its Mahindra M5Electro in Spain this week before being formally announced by the team as a full-time driver.
Mahindra team principal Dilbagh Gill would not go in to details regarding his team line-up when contacted by e-racing365 but did say that “our Season Five line-up will be become known soon, including our reserve and development drivers.”
