I vote for Rotary (duh)

I did not list all engine designs but I think it would go something like this:
1. rotary or V12 tossup?
2. straight 6
3. V10
4. V8
5. flat 6
6. V6
7. straight 5
8. 4 banger

turbodiesel, i just have quick question. why do you target the s2k owners so much? really i own both cars and i like them both equally. but almost every time i see you post, its has negative things against s2k ppl. i understand you love the 8 , and so do i. but a person liking of a sport car should not effect you should it?
I may not like certain cars, but i wont attack the owners either. its there opinion so why should it effect me any. any how just wondering.

Not a simple discussion, do you want to define “smooth and balanced” by inherent engine design or subjective sound and feel? One doesn’t always lead to the other. A boxer engine should be inherently smooth, but my BMW boxer twin does not feel any smoother than the inline four on my Honda. A inline six should also be inherently smooth, but I’ve driven many 60 degree V6’s that feel as smooth as my bud’s 3 series. Never drove a V12, but tried a flat 12 that should have felt smooth, but revved slowly and didn't feel as smooth as I expected.
Noise, vibration and harshness engineering, chassis rigidity, engine mounting, etc. usually takes precedence over engine design. Lets not forget that inherently unbalanced engines, like a 45 degree Harley v-twin, also have their share of admirers for not being smooth.
But the renesis is one example where it feels as smooth as it should. I have yet to try an engine that combines smoothness, fast revs and a linear power delivery as well as the renesis.

9291150 made some good points. However I would have to say if the engines were bolted to plain metal, that the rotary would take the cake closely followed by a V12. The four banger in my R1 is pretty smooth though.
And I happen to be one of the admirers of the unbalanced V-Twins in my Harleys. Riding would be the same if they were smooth.

By design, the more pistons a motor has, the smoother it will be..
A 4 cylinder will always idle rough, and have a much more "ON - OFF" power delivery versus an 8 cylinder. The reason for this, I'm not sure about non-US engines...the 4 cylinder is using 1/2 of its pistons at all time. An 8 cylinder is never using more then 1/4 of its cylinders.
At least..thats how it was explained to me? I was explained this is the reason for the change in exhaust note. The 4 cylinders sound harsh and raspy, as the 6, 8, 10, 12 cylinders all sound smoother as you work your way up.
I voted rotary, simply because it is obviously the smoothest running engine. It spins...theres no "up! down! up! down!", so obviously it HAS to be the smoothest.

Anybody ever been able to verify/duplicate the "coin trick".
For those who dont know what the "coin trick" is, Its an old rotary party trick where you take a running wankel engine and stand a coin up on its end. Ive heard about it while I was doing a school report on the wankel, but Ive never seen pictures/video/anybody say they have done it.
I voted wankel because I have had to hold the trottle open and hold V8s at 2000 RPM and it vibrated like a *****
And Im a really huge rotartd

Are you retarded? Why are you making yet another username and punishing us with your stupid posts? Unless of course it's just another idiot thinking he's being cute with multiple usernames...

its a good question as a V12 and an I6 are perfectly balanced engines, with the V12 getting a nod with closer power pulses...
wish i could drive a V12 and compare it to a rotary
