The Andretti Formula E team is in talks with BMW about a possible future partnership in the all-electric series.
A source at the team confirmed that talks had been "developing between the parties for some months, but no definitive progression of a way forward had yet been realised or confirmed.’"
Informed sources have told Motorsport.com that a potential link-up with the American team could happen, but that any deal is "unlikely to take place, in a full capacity at least," for Formula E's third season.
Motorsport.com can also reveal that BMW will not, as a manufacturer, participate in the forthcoming tender for the supply of chassis or batteries for the 2018/19 season.
The German manufacturer is believed to be confident in its knowledge and technology gained through the i-brand series to promote its electric vision, but they are open to accessing further marketing through racing in Formula E with the Andretti team in the near future.
However, a BMW identity in Formula E is far from certain, with a board decision yet to be confirmed to green light a tie-up with the American team.
Andretti have a re-homologated their ATEC-01 car ready for season three of the series, but are looking for an additional partner to race with for the next campaign.
A potential announcement about a possible BMW future in Formula E, rumoured to take place at Berlin in May, has been suggested by an informed source as "highly unlikely".
