Very interesting post.AdiS said:Something I forgot the mention, which is something that hardly anyone ever talks about is the difference in character. Often I hear people describe the 330i as the 'poor man's M3'. If you take character into account, nothing could be further from the truth. That is not to say that the 330i is a bad (or slow) car, but the way it feels overall is just so different to the M3.
The easiest example I can use is how the engine responds. On the M3, the throttle is razor sharp, and the power delivery is urgent with a real sense of occasion. The S54 makes a glorious noise under full load, and really screams to redline. You really are well rewarded for driving the car hard.
The 330i, on the other hand, delivers good performance but with so much less drama. The throttling on the M54 is quite lethargic, and the power delivery is smooth and torquey, but it doesn't really feel all that exciting when reaching redline. The sound is also quite muted. This all contributes to a refined and pleasant experience, but it's really not all that exciting. The car actually feels a little slower than it actually is because it's so smooth and refined.
I have never experienced the E46 M, and maybe its a good thing, because while I could buy one, not sure if I would keep up with the maintenance, which is the important part. Back when Zach (I think) was selling his, I inquired, but he subtlety hinted at "no". Which was good.
But now, I have 2 330s and something is up. The one, on 200ks, feels like your explanation. Has power, but delivered smoothly and no real drama. But the white 330i in my showroom thread, is different. The power feels the same, but more brutal. It screams for more when I drive it. Now I aint comparing it to the M, there is no way. But I think there is a gap in the history of this car, that I need to figure out. It may have had another map/tune loaded that I dont know about, or something. Its not a turbo or supercharger, that would be easy to spot. It is just, the character of the car is different from your explanation, and the other 330i I am comparing it to.
