The 2003 Bentley is a complete redesign of the previous 2001-2002 chassis.  All the bodywork, a new monocoque, and new suspension.  Nothing was retained except the engine.  As Peter Elleray points out, "Quite an undertaking for one year, although obviously worth the effort!"

See Bentley designer Peter Elleary's thoughts about the design and development of the Bentley LMGTPs.
