CR was on to something. C&D's most recent M5 comparison test corroborates what others including CR have been saying about the new series of BMWs.

The F80 and F82 were given their own "F" codes as BMW M realized that they replaced or modified 80% of the F10 M5 so it would meet their requirements. 80% of a changed product is not the same product- they anticipated the same for the new M3/4 and requested separate internal codes for development.
