Although it's a shame to see BMW veer away from heritage but unfortunately it si the way to go this day and age.
Forced induction = Much more potential power tied in with better fuel economy
Back in the day when Toyota had the Supra, Mazda with RX7, Nissan with 300z, Mitsu with the 3000GT, etc that was exciting and look at them now!
Toyota with nothing, Mazda NA RX8, Nissan with NA 350z, etc........makes no sense to me.
BMW I think is headed in the right direction
