Could the vehicle pictured in this scanned photo from an official Bugatti invitation to a special event at the Frankfurt Motor Show in September be depicting the firm's long-rumored four-door sports sedan? Well, the only thing we can be certain of is that it isn't the Veyron - or at least not the current generation model.

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.
