Don't get me wrong, I think it will be a fabulous car overall, and will likely surpass the e9x in most ways, however, getting power properly to the ground will be an issue. This is why even massive hp cars like a 640hp Viper still max out on their 0-60 times in the mid 3's even with 345 rubber.

I'll be extremely interested in seeing how BMW plays this issue. For instance, there's no particular reason why they couldn't restrict boost in first (and possibly second) gear. Instead of the nominal 18 psi or so, they'd give you 9, and 14 in second, or whatever they deem appropriate for an optimum-traction day.
Presto! Clean launches and terrific ETs for those of us who are stoplight/drag strip bandits.
Maybe a switch to turn it off if you feel like hooning around?
