No automobile engie fires on 2 cylinders at the same time. Think about it. If you ever changed a cap and rotor it uses seperate wires. You never run 2 wires from one post for it to fire in 2 cylinders at once. only thing close i the old Mazda engines but they ran 2 spark plgs per cylinders.
Inline or slant 6 are naturally ballanced because of thier design. Why do you think that most sports cars (Toyota supras, sabb, porchea, ect) opt for theI6. Smoth running and if tuned right can punch out enormus torque. They also last longer because they dont put as much stress on all rotating parts by it vibrating like mad. Ask and true mechanic and the engine that would first come off thier lips as being thebest long lasting motor ever built and they will all say chryslers slant 6. You cannot kill that motor no matter how much you try. Any other I6 would come next. Chevey did the right thing as well bringing back the I6 for thier Trail Blazer Series suv. Thoes cars should stay on the road for quite some time before the engine dies.
Now if you want a engine that is going to last you several hundreed thousand miles get a I6 Diesel burning engine. Smooth, tons of torque, and last forever.

Just my $.02 from a mechanics perspective...
Inline engines produce more torque than V configurations. However due to the higher center of gravity and rotational torque - inline engines are known to have their engine mounts wear faster. They eventually begin to bounce or jerk under heavy accelerations & while starting. The v configurations, although due to counterbalancing have reduced torque, do not suffer from this premature wearing of the mounts, because of a lower center of gravity and more balanced mass distribution of the engine block.

I am beginning to find that besides Zenmervolt, FrustratedUser, and a couple other technical people, everyone else on ATOT has absolutely no idea about how engines operate, yet still wants to throw their 2 cents in. This trend culminates with this post:
"V6 is smoother becuase there are more balanced simply by design. think of it as the cylinders are pushing against each other when they mcve up n down. in theory each piston show move with the same force so the forces cancle out.
in a in line engine, the pistons push against the crank, and after a while you start getting them ticking noises. they are more unbalanced. but when its done right like BMW's inline 6's they are every good."
Ugh.
Inline 6's and V12's are inherently balanced.

To add comments to the I6 configuration....
The straight 6 also sounds a heluva lot better than a V6..... much like a Ferrari V12...
Most 6 cylinder diesel engines are inlines also. Most of the Datsun/Nissan, Mercedes, and Toyota inline engines are great designs of the inline 6.
I would take an inline 6 over a V6 anyday.

I think I6's tend to have a droning sound. V6's sound better.
In TF&F (hate that movie) when they wanted engine sounds for the Supra they used a 300ZX for its sound.

No. They fire one at a time, like all engines. In all engines, opposing cylinders travel up and down together but in opposing sequence of the 4 cycles. In the boxer design, this makes it look like the pistons fire into each other, when in fact when one piston is firing, its opposing piston on the opposite bank is in the intake cycle.
Bingo.
Quick 6 cylinder engine comparison:
For smoothness, balance, and strength: I6 > H6 > VR6 > V6
For packaging: VR6, V6 > H6 > I6
For inexpensive manufacturing cost: V6 > VR6 > I6 > H6

You say you hate Fast & Furious yet you use it to help make your point? wtf...
Anyway, I6 >>>>> V6, in terms of sound.

Inline engines have a longer stroke than the compact v configurations.
Any freshman who has had a first year physics course knows that a longer arm turning a radial device has more torque than a shorter arm.
Correct... Only because a V12 is 2 inline 6's put together in one engine.

Engine sound is almost entirely dependent on exhaust port, header, and exhaust design, and the number of cylinders... not engine configuration itself.
You know the unusual Subaru boxer sound? That's because of Subaru's factory unequal length header design. If you put equal length headers on, it sounds just like a Honda I4. I have seen it, heard it, and am completely serious.
I have one, with dual exhaust and a cold air intake and performance chip. I love driving it. You really feel the torque in the mid-range rpms. Surprises a lot of "ricers" with its speed.

The problem there is that you're introducing another variable than just the engine's cylinder arrangement, which makes your comparison invalid. When comparing two different cylinder arrangements you absolutely must assume identical bore and stroke.
It's true that most I6 engines have a smaller bore and longer stroke, but that is not something that is necessarily inherent in the inline arrangement, so you cannot use it as a rationale for believing that an I6 has more torque than a V6 by default.

You're kidding, right? If you put equal length headers on a VW flat 4 is sure as hell doesn't have the same cadence as an I4. Firing order has a lot to do with how an engine sounds too. Also crank design. A flat crank V8 sounds very different from a 90 degree crank V8.

what kind of screwed-up engine design is THAT?
It would be more expensive than a V8, and not offer any advantages (and quite a few disadvantages).
Maybe I'm just reading your diagram wrong...I hope.
As for the original topic...I like I6's, they're sweet engines. I dislike V6s in general, since I feel there are few things a V6 can do that a V8 or I4 can't. Of course, there are a few niches where V6's work out...say, you want about 200hp...but I'd prefer to add 75 horses and lose 1-2 MPG with a V8, in that case.
Agreed, the Supra was more expensive and far superior to any straight-six BMW 'back in the day. It's not fair to compare different classes of cars like that.
First of all not all I6 engines have a longer stroke than V6's. You can give an I6 a long stroke, or you can give it a shorter stroke. There is nothing inherent in the I6's design that dictates that it must have a longer stroke than a V6. My Nissan's V6 has a longer stroke than Nissan's I6 in the Skyline. Bore is about the same, but their I6's stroke is shorter.
Also, that's been a point of contention forever in the domestic circles. You had people who believed that when they stroked their engine, it was the longer stroke itself which gave them the added torque. Others disagreed and believed that it was strictly the increase in displacement from stroking it that gave them more torque. They pointed out that if you increased the bore size to deliver the same displacement as you'd get if you stroked the engine, you'd have the same amount of torque. As a benefit, you can rev the engine higher if it was a larger bore to stroke ratio. If you stroke a 350 to 383 ci, you get more torque. But it's not because you gave it a longer stroke, it's because you gave it more displacement.
