Realizing that the success in "The Most Successful F1 Cars Ever" means the CSI/FISA World Championship for Drivers/FIA F1 World Championship, which meant, in turn, excluding any successes in those events outside the CSI/FISA/FIA championships -- which is always the implication of course, there was a statement at the end of the article that somewhat stumped me:
2. Modern day 'B' versions are not listed as separate chassis as usually only comparatively minor modifications have been made. Further back in time B versions are listed separately wherever relevant as they were often more different from each other as successive years' chassis in the modern era. If the different versions of these chassis are listed as one, the top ten would read 1: McLaren MP4/2, MP4/2B, MP4/2C, 2 wins; 2: Lotus 72C, 72D, 72E, 20 wins; 3: Williams FW11, FW11B, 18 wins; 4: Williams FW14, FW14B 17 wins; 5: McLaren MP4/5, MP4/5B 16 wins; 6: McLaren M23, 16 wins; 7: McLaren MP4/4, 15 wins; 8: Ferrari F2002, 15 wins; 9: Ferrari 500: 14 wins; 10: Lotus 25, 14 wins.
Not seeing the Lotus Type 72 listed anywhere was a real surprise until I saw this footnote. It would have been better to have had a better idea of the criteria prior to the listing in my opinion. Naturally, there are those who could argue that the Ferrari 500 doesn't belong on the list since it was an F2 car. Given that the McLaren M23 was extensively modified over its career in much the same matter as the Lotus Type 72, I better understand why I avoid such articles when and where possible!
MY view is the "B" specification and so forth is fairly irrelevant when viewing a type in the overall sense. In the case of Lotus, one could invoke the mystifying "25B" or "25C" designations that were used in the Press which the team never used. Indeed, in the case of the Type 72 the team often avoided used the type number altogether, the Official Designation being the John Player Special.
Or is this just another case of the usual inability to just leave well enough alone?
