Whoa, apparently Honda had this V6 engine with VCM out last year....

Here's an excerpt to address Kensuke's issue, I like the last paragraph.
Quote:
When operating in three-cylinder mode, engine vibration is reduced by extrapolating vibration from the change in crankshaft rotation speed and sending the information to an "active control" engine mounting that compresses/extends an actuator in same-phase, same-period motion to dampen the movement.
Similarly, a speaker creates an opposite phase sound for a quieter interior. The driver, Honda says, will be left unaware of changes in cylinder activation.
