The three banks will act as joint global coordinators on the initial public offering (IPO) of Ampere, the source said.
Citigroup , HSBC , Morgan Stanley , Natixis and Societe Generale will act as joint bookrunners, the source said, adding that Mediobanca will be the co-lead manager.
Bloomberg was first to report the names of the investment banks on Ampere's IPO. Renault aims to list Ampere in Paris this year, depending on market conditions. Sources have said the unit could be valued at up to 10 billion euros ($10.96 billion).
Renault's management has not yet given a valuation for the unit, saying it was up to the market to do so.
The banks involved declined to comment or had no immediate comment. Renault declined to comment on the names or roles of the banks picked for the planned listing.
