I am really curious what BMW will do for the F3x/8x M3/4s. I'm amazed that they've hidden it thus far. Beyond a straight 6 with direct injection and turbos, I'm not sure. If they use an electric motor to spool up one of the two turbos (I can only imagine it'll be a series turbo configuration), then it'd be already pretty unique. I think they'll also try to run as much as they can off electricity including all the pumps.
True. It probably won't reach the same level as the E46 in its cult classic status, but I definitely think it'll be a highly sought-after car 10-20 years from now. I've been reading that the E9x M3 has been very reliable to date which should also boost its desirability in the years to come.
In terms of the F3/8X M3/4s, I've read rumors that it'll have a TRI-turbo setup.. I don't quite understand how or why you'd need three turbos, unless they're all three different sizes for the low/mid/high RPM ranges, but an electrically-spooled turbo would probably suffice in addressing the low/mid RPM ranges. Two turbos make sense to me.
