Ford could sell Volvo because of the bad results of the PAG (Premier Automotive Group with Jaguar, Land Rover, Aston Martin and Volvo).
Renault would be interested and it'd be a new challenge for Carlos Gohsn who has already saved Nissan (two years in advance !). Volvo is little beside Nissan, so it's quite realistic.
There has already been a partnership between Volvo and Renault for the engines.
