After some extensive research, I've got the lineage of this car's development over its 4 seasons mapped out (2007-2010, inclusive). While there were many small changes across the car, the most visible external evolution over that time was focussed on the rear panels and the shaping of the rear fenders. This means the forward bodywork and chassis can carry through all versions... Le Mans low-drag nose being a notable exception.
The 2009/2010 version with the ACO's narrow-wing regulations is modeled here.More »
