I think a little clarification on what you meant is in order. What exactly do you think vibrates, the I6 or V6?
No matter what you say, you're at least 50% wrong...
An inline-6 engine is inherently balanced and does not have any second-order vibration characteristics. Its smooth nature is why BMW keeps using it and, until recently, it was the "engine of choice" in Jags and Mercedes Benzes.
A V6 can also be inherently balanced... "can" if it is a 60-degree V design. The problem with many Amurrican V6s is that the motor is a 90-degree V8 with two cylinders chopped off. A 90-degree V6 will vibrate, a 60-degree will not.
