Lotus 80:
Reason: http://www.connectingrod.it/HistoricalR ... o_eng.html
Lotus 76:
Reason: Only finished 1 of the 9 races it started.
Williams FW20:
Reason: No wins in 1998 after clinching 5 of 6 constructors crowns the years before.
Williams FW12:
Reason: Normally aspirated in the last year of the last turbo era. Plus pitted against the MP4/4
Renault R27:
Reason: No wins after two years of winning the constructors title.
Ferrari F2005 (debatable, I know):
Reason: Only one gifted win after half a decade of winning everything.
I wonder if the RB10 might join the club some day. :-"
