Not the smoothest engine over 6k

Might be right, forgot the 90's era M3 was a 4. I owned a 91 318IS and it was very smooth but only had 118 hp.

Inline 4's need heavy harmonic dampers to make them smooth. Pancake engines don't.

[Veovius]

Do boxer 4s have a harmonic balancer? Don't in line 4s need to have one?

Agreed! I miss that sound a lot, just not the maintenance bill

The OP said nothing about owning a M3 or S2000. His profile says he drives a Yaris.

How rude. It is obviously implied by the original poster that he shared his comparison of the other listed vehicles as having exceeded 6K RPM in those. That leaves everyone to think that you don't believe the listed makes could exceed 6K RPM. So I guess were all idiots. Thanks.

i know people who own the yaris right now with 200,000 miles on 'em! (2008)
i don't think they care "two shits" whether,or not it's a "refined" car!..just sayin'

Op had a valid point/concern and people resorted to being ****s about his Yaris. Sounds about right for the internet.

Not everything is a matter of opinion. Balance is about physics.

I was just messing around. I didn't mean any hard feelings, haha! One of my friends actually has a Yaris and it is a great little car (for the money). As long as you're a fellow FR-S/BRZ owner you're a good man in my book.

My 6000-7500 became a LOT more smooth around 10k miles or so.

I know what smooth is - my other engine is a 1JZGTE

Some Honda owners don't know their engine uses balance shafts..

Having owned 10 Hondas and 1 Acura I can attest to the smoothness of Honda 4 cylinder engines (balance shafts being irrelevant to the topic), but I'm not convinced the Subaru flat 4 is any smoother. My opinion.

If you measure "smoothness" with your butt and your fingers it will be entirely subjective and any argument is pointless.

Subaru is known for being a bit rougher around the edges, they have stiffer motor mounts and less dampening in the cabins, Hondas are trying to toe the line between luxury and economy and as such have more damping.

The Honda will "feel" smoother, but what's actually happening in the engine is a lot of extra mass and development time get added to hide the vibrations that occur in the I4 engine arrangement, while boxer engines are dynamically in balance such that they don't need balance shafts or nearly as many tuned mass dampers.

You can say your Honda is "smoother", by most counts most people will agree with you. Saying your Honda I4 is "smoother" than any boxer engine is going to encourage lengthy heated arguments.

How can balance shafts be irrelevant to the subject when they are used for the purpose of "balancing" the rotating mass of an engine that is not balanced by design?
Whereas the boxer engine needs no special device to mask the vibrations.
What you perceive as smoothness is balance shafts, hydraulic motor mounts, harmonic balancers... Etc...
The point is, the boxer engine is inherently smoother by design than any inline 4 banger.. What you feel as the end result is due to many other things which cause NVH..
