Honda is one of the few, if not the ONLY car manufacturer which merges innovation and new ideas, efficiency, performance and environment awareness into some really sincere and fruit bearing research.
Good show!! Keep up the good work.

This is not a new idea. Back in the early 80's you could buy a Cadillac with a V8 that would sometimes only use 4 or 6 cylinders as needed. I've never driven one of these strange beasts, but from what I hear, the transition was often not smooth, and sometimes the engine would get stuck in a certain mode. Sure would suck to be driving a huge Caddie around with 4 cylinders for power. I think most owners of those cars ended up getting the engine controls modified so that the engine would simply run on 8 cylinders all the time.
Now I have a lot more faith in Honda engineering, and this will probably be as smooth as the gas/electric shenanigans going on under the hood in the hybrids, but this is not an innovative idea. Also I understand that GM is bringing back ?Displacement on Demand? to their vehicles as well.

Yeah I've read discussion about that Caddy when talk about this "new" engine technology was brought up months ago.
With the increase in technological advancements since GM's attempt at "displacement on demand", improved manufacturing processes and quality checks, and Honda's financial commitment to R&D, I'm pretty certain this engine will be a winner.
Grant it I guess one must allow for certain bugs to arise, but I can only see a marginal drop in quality if any at all.

Well, for me it is innovative since there's no other car currently available with a similar system.
It's like saying the Rotatory engine in the Mazda RX8 isn't innovative because many other manufacturers did it in the past. I think they are, because the engines made now have nothing to do with those old ones, even if of course, when thinking about the problem in the simpliest way, it is the same: "a rotatory engine".
Actually, Honda don't stop putting new ideas in the product line, and there aren't many manufacturers that could say so. The majority of them keep on doing the same thing, many of them do it very well, but it is still the same thing. I've been hearing for years that the naturally aspirated petrol engines developpement couldn't be improoved anymore because it was at its limits.
And despite those who say that, Honda has come in the past years with: a 9000rpm VTEC engine, i-VTEC, i-DSi, VTEC-IMA (Insight), the combination of IMA-VTEC and iDSi (Civic Hybrid), and now this "Variable Cylinder Management"
Also don't forget that it's quite easy to make a technology available as a prototype, or in very special and expensive cars.
The huggest merit of Honda isn't the fact that they innovate, but that they put all those innovations in mainstream models that are available to the big public.
The Inspire isn't a very special car, it should cost less than many 3 series, and the 3.0 version isn't a special one, it's the ONLY one available.
Mercedes announced their research on a similar system in 1996, and since them they've been trying it on an S500. But, first this car costes 100000+ $, and second, they haven't still reached the technology maturity needed to launch the car.

well. it could be that technology equipment wasn't as sophisicated as today, oue cars has been aidded by computer, same for our engine, beside, sensors and on board computer technology weren't ready at that time. a lot of "old concept" has been reborn with new technology and proven to be problem free. one thing from my observation is that, Caddi's quality really ... ha.. don't want to mention about it. ppl knows what I am trying to say

i think BMW too is up there as far as engine innovations goes.

Civic Hybrid has it.

Not exactly. The Civic Hybrid only idles cylinders during closed throttle deceleration to obtain maximum energy recovery in the IMA system. The use of the idled cylinder system while running under light loads is new - although I'm sure the actual mechanism is the same.
