Replying to: ljgbjg (Apr 09, 2008 5:23 am) I think the VCM is just hype from Honda in order to sell the V6 engine. The way the VCM work; it shuts down the fuel injectors for a specific cylinders, and fill the cylinder with air instead. According to Honda this system will result in an increase in MPG by 1 or 2 miles. I do not agree, with Honda. The fact that the cylinder is still moving up and down, result in the other active cylinders to bear the burden of the weight of the inactive cylinders. This almost cancel the effect of saving couple drops of fuel every x RPM. If Honda did use a transmission between each 3 cylinders bank, the result will be real 4 or 5 MPG increase; but the problem this approach will cost Honda more money; by consequence they need to raise their price by at least $1200 for the transmission. On my wife’s 2007 Honda Odyssey EX. No VCM, I managed 25MPG on a highway and 21MPG on avg. 25% city / 75 % highway. I heard people with the VCM are getting 17 MPG on avg. This proves my point. This is one of the reason that Honda is going to get ride of the VCM technology, and replace it with Diesel. The problem you’ll have to paye a hefty premium to get that car, plus the diesel price is $1 more than the gas for one gallon. You do the math, and you’ll see that it’s better to buy a good 4 cylinder car that suite your needs.

Check out some V8's from GM - at highway speeds they cruise at 2000 RPM at 80MPH because of the overdrive. Result? 28-29 MPH from a V8 - and no VCM!

The highest I have seen on a 150 mile highway trip was 28.8. When I traded in my 2005 V6 without VCM I would average about 31 mpg. highway. That 31 mpg was pretty consistent over the three years that I owned the 2005. Replies to this message: ljgbjg (Apr 09, 2008 6:57 am)

Replying to: donegal (Apr 09, 2008 6:51 am) Yeah - I cannot pinpoint a particular reason - VCM, increased weight, drive by wire, whatever, but it pretty clearly seems that the the verdict for the 2008's is that they are not as economical as the 7th generation, regardless of which engine you are talking about. Our 2005 V6 Coupe with AT consistently got 29-30 highway and I am not the slowest driver around. That was at 75-80 MPH.

Take this with a grain of sand, but I believe somebody else has said it. Doesn't the first year of a generation always have kinks that need to be worked out? I don't own an 08, because I can't afford a new car, but I would guess that next year in the 09 model Honda will be changing things in response to complaints they've doubtlessly received. Also, winter is almost over and everybody who does own one should most likely see an improvement in gas mileage.   New cars shouldn't be released in Fall, especially when they're the first year of a generation. Rather they should be released in Fall so people have a better idea what the mileage will be when the engine is 'broken in'. Then again I'm not well-versed in the mechanical side of things. The 09 should be an improvement over what people are saying is wrong with the 08.   I've heard that my model an 03 was plagued with problems when it was released too, but I haven't heard too much from 04 and up. I just started driving 4 years ago so I would know all the specifics.

Just my second post on this board - thought I'd revisit. I posted previously regarding the V6 VCM issue. Still no issues with the VCM - I really wonder if all the fuss is about transmission shifts - as they can be very noticeable - but you can see the tach changes as the shifts occur. I swear there's no feeling at all from the VCM. Last tank this AM got me 23.42 mpg - my best so far. Got 21 even last tank, and 22-23 the other tanks. My tank this morning cost me just under $60, which would have cost $106 for my former Chevy Tahoe, so I'm a happy camper. My goal was to double my gas mileage, and I'm looking like I'll be short of that, but I love the V6!   Happy driving. Replies to this message: ljgbjg (Apr 09, 2008 7:39 am)

Replying to: fldonahue (Apr 09, 2008 7:29 am) VCM - "I really wonder if all the fuss is about transmission shifts"    I can assure you it was not transmission shifts - I know I know the difference(as do the others who had issue too I am sure), and at 65-70 MPH there should be no transmission shifts with the cruise control on. No, there was a definite "surging" sensation when the ECO light went on and off. In my case, after about 2000 miles, it has disappeared - so I can speak of VCM from two perspectives. It WAS horribly unacceptable before - surging, jerky, "torque on/torque off" sensation as if I was pushing on and off the accelerator pedal - and I was not - it was set on cruise on a level road! NOW? I cannot notice a thing. Something happened - maybe the active engine mounts are now working and weren't before and had to gert broken in? I don't know - but I do know VCM from BOTH perspectives. You should consider yourself among the lucky who never had problems. Believe me - if you had, you too would have been thinking about getting rid of the car.

Let's try to talk about the VCM in the actual VCM discussion and leave this discussion for actual fuel economy reporting for all Accords.   You can report VCM engine fuel economy here or there - or both - but let's not get sidetracked on the VCM itself in this topic.   Thanks!

Replying to: dpmeersman (Apr 09, 2008 6:05 am) It is interesting to see honda find a different wind tunnel, the gen 7 used to get 0.30 Cd. And now it's 0.34   My Gen 7 V6 gets 29mpg on with 85% highway (mostly under 65mph) with 6k on the odo. I am expecting to see 32mpg+ after 20k. Since 6MT could get over 40mpg (full highway), i think 35mpg+ is obtainable on gen7 V6 auto.
