Are inline 6 engines inherently smoother than 60 degree V6s?

Or is it just perception since companies who make straight sixes, like BMW, probably make better engines than companies like GM who make more V6s.

Kinja'd!!!

Because I’ve decided my dream/next DD will have either an inline six or V8, bench seats, column shifted automatic, and either be a liftback or have a ginormous trunk.

I thought that i6 were inherintly balanced and v6 needed balancing shafts. But

60 degree V6s don’t, but 90 degree V6s do IIRC.

GM made inline 5s and 6s for a while in the Trailblazer, Colorado, Hummer H3, etc. I’ll bet one of those had a bench seat option.

A I6 is better balanced, but can’t easily be used in a FWD configuration. While this isn’t a problem for BMW it does become an issue for a mainstream manufacturer to justifly a model specific engine.

Wait, wait, you want a V8, column shifter, bench seats, and a huge trunk? We should talk.

V6s are basically two I3s sharing a crank. Odd-cylinder count engines are rough because there is always a more cylinders moving in one direction than in the opposite. They need balance shafts and counterweights to run smoothly.

“Packaging is a big issue with the straight-six, though. It’s just kind of hard to fit in cars, can throw off the center of gravity, is nearly impossible for front-wheel-drive setups, and loses some rigidity over other engine options due to being a little stretched out and skinny.

V6 engines litter the lot of current supercars, including the Nissan GT-R and new Acura NSX. It’s more compact, making it easier to snuggle in some turbocharging, works better for front-wheel-drive applications, and makes it easier to fill a vehicle lineup with the same basic engine layout. Copy/Paste.”

Never said impossible

OMG yes. Out of the box, the i6 is inherently balanced, and one of the three perfect engines. See also: V12 and a boxer 6

The V6 is a compromise for mostly packaging and fitment. Compared to the three mentioned above, the V6 is a hot mess.

I would guess that they are. The direction of motion and weight are the same with inline, which would mean that they perfectly cancel out, vs going in different directions.

If you go back further, an I6 was the standard engine in the Camaro through 1979.

My 240Z is smooth, my truck is an I6 but it’s a flathead from the 50's so I’m not sure it will help the argument.

yup! And that’s just another reason they should’ve used the Atlas in the new Camaro :o)

I liked the idea of a nice modern American DOHC I6

If the new Camaro had the Atlas and T-tops it would almost be awesome enough to look past not being able to see out of it.

Inline-6 engines are smoother because the piston movements are naturally balanced in typical designs. In a 60-degree design there are ways to arrange the firing order but it’s never as smooth as an inline-6.

A 90-degree V6 has too many perpendicular-action forces at play to be smooth without a good counter-balance design. Inline-4s have issues due to having too few cylinders, and inline 3s or 5s are just weird. V8s can be fairly smooth - and v12s can be buttery-smooth. Nothing beats an electric though - but they don’t make real vroom-vroom noises.

In theory, yes, straight sixes are more balanced. In practice the balance shafts and tolerances have gotten good enough lately that a modern v6 is going to be better balanced than a straight six of yore.

I-6's and V12's are the only engine configurations that inherently have perfect balance. V6's pretty much always require at least one balance shaft to reduce NVH.
