Horsepower can be very misleading. In fact, M3 driver should know this the most - it is surpassed in Horsepower by a lot of its competition (C63) but eventually ends up being the better car due to balance and how it applies that power.
I hope they make more responsive, direct, and tactile and precise feeling cars, even if they are slower. In other words, this is what Porsche does, especially with the Cayman and Boxster.
Power gets old quickly; but how a great car feels under your control never does, even if it's not that most powerful.
