Less weight is a very good thing. But shedding 200-300lb won't be enough to keep the M3 competitive IMO, as it will only improve power to weight by a mere 5.5%. This is the equivalent of increasing power on the E9X by 23hp...
Maybe BMW will surprise us by underrating the F80/F82 as they have with all other recent engines. If 420 quoted translates in 450ish actual, then I'm happy
BTW, that render does look good
To make the argument worse, there are many who argue that mid 2010 models and later benefit from a SW update to the ECU that seems to result in about 20 more hp on dynos. With many of the 2010.5s already putting out about 440 hp on a dyno, there isn't that much difference it would appear.
