Went to the Nurburing 24H race again this year and there was a Lexus LF-A racing with four toyota test drivers( so i was told). The car was disguised with box arches and squared off bumpers but you could see the full racing fuel cell and quick fueling system. Pictures are pages 6,9,23,26,30. Lots of other pictures so have a look around.
