The 1999 CLR design wasn't particularly innovative.  But Mercedes showed up at Le Mans with a car they felt should win.  Tens of thousands of miles had been spent testing, nothing had been left to chance.  But it soon became clear that both BMW and Toyota had equipment the equal, if not simply superior, so too the upstart Panoz.  Ultimately though, the CLR is noteworthy for one thing in particular, the very public and very dramatic aerodynamic induced back flips that it underwent on three separate occasions at Le Mans in 1999.
