Don't know why they switched from the I6 to the V6. I know the I6 has 24 valves and the V6 has 18. The I6 is a higher reving engine as it cruises at higher RPM's than the V6, but that's prbably due to the electronc vs mechanical tranny.

IMO, the I6 is a stronger and "bulletproof" engine. But prone to the headgastket problems in the earlier w202 years. Tho I think the V6 is more fuel efficient than the I6.
Also the harmonic balancer can go out of whack and cause headaches, but can't think of anything else right now.

97 had the last i-6.
i-6's more balanced and will result for better weight distribution for the whole car. That's why BMW ain't giving up on their i-6, although it's pretty much to the end of how far they can go on power w/o force induction in the E46 M3's engine. I love the sound of the M3 I-6 too.
v-6's more efficient for fuel consumption, save a lot of space up front, but the weight is focused in one area. It's also less costly to built.

BMW's I-6s all sound good. The 325 sounds a bit sweeter than the 328/330 and the M3 sounds like a 325 with an overdose of steriods.
