I'm a bit torn between the previous M3's and this new upcoming one.
I love my current E46 M3, and I absolutely love the screaming straight 6 and the 8k RPM redline. It sings when I push it, and it's absolutely amazing in every aspect (I'm sure many E92 M3 owners feel the same). But with this new M3/M4, we'll be getting better fuel economy, more torque, and more importantly - more power. I'll definitely miss the old M3's with their N/A engines, but it's time to move on with the times. Turbo cars are more fuel efficient, and powerful - it's the right direction to move in logically. But being an enthusiast, I'm finding it difficult to cope with the idea of an M3 that doesn't scream and doesn't have an 8k RPM redline.
Time will tell, we'll just have to wait until it's officially released to see what's going on. Either way, when this car is released and if I don't like it - I'll just jump on a used E92 for a much cheaper price since people will be wanting to sell theirs for the new one
