Internet rumors, which have not been confirmed in any way by Bugatti or the VW Group for that matter, say that it may be a close-to-production concept study for a new uber-luxurious sedan heavily based on the underpinnings of the forthcoming Bentley Arnage replacement known as the 'Grand Bentley'.
For the time being and until we discover something new, we'll just keep this in the 'Rumorville' department.
