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!

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.

...I have tried my dead level best to break 40 with my 6M. I have not (yet) been able to get past 39, Where is the dude that got 40 miles per gallon? I will buy the Crown Royal.
 
Seriously, 40 is hard to accomplish. I have really tried.
 
best, ez....

MPG: city with lite hwy and 80 to 85 F days (summer's not here yet) no real use of the A/C. 1st tank at 17 mpg (yes had to adjust my style of driving), 2nd tank at 24.6, then 24.6 again and last tank at 23.1 today.... I'm satisfied with the blend of economy, quality, fun and reliability this auto provides.

Anyone else remember the old annual Mobil Fuel Economy Challenges? Maybe they need to be brought back!

"No projections are needed in the wind tunnel, though, as the Accord has already bettered its performance due to a drop in the coefficient of drag from 0.34 to 0.31.
 
I'd like to know how they accomplished that as the frontal area does appear to be more substantial than the gen 7's. "
 
Keep in mind that the frontal area is seperate from the drag. To get total wind resistance you multiply the two together.
 
I also thought the gen 7 was .30.
 
EZ - you will get 40 eventually. That sixth gear is your secret weapon. Have you tried 0w-20 synthetic yet? Have you tried 40 psi (or the max sidewall - should be 44). Choose the warmest day you can stand without A/C. Check the weather channel to make sure there won't be wind (or you could cheat and look for a tailwind) and I think you can make it.
 
Malmousa - I am very suprised to see a hypermiler getting 25 mpg in the new Accord - what mileage were you getting in previous cars.

5 speed AT/6 speed MT - makes no difference in MPG
"That sixth gear is your secret weapon"
 
The real issue is the final drive ratio. The final drive in the V6 6 speed coupe is 3.55, and the automatic V6, 4.31. Very strange actually - usually just the opposite because the AT has the advantage of the torque converter multiplier effect and usually has the lower final drive.

The 6 speed coupe V6 versus the AT V6 VCM SHOULD give better MPG, unless the VCM really does what it is touted to do. I have my doubts.

Here is the link to the Motor Trend article:
 
http://www.motortrend.com/roadtests/sedans/112_0802_midsize_sedan_comparison/
 
They claimed the Cd numbers I quoted. I believe that I've seen .30 for the gen 7 Accord as well. One of the thoughts I have every day as I walk down my driveway after getting the mail and I look at my 08 is Wow! big car! Lots of frontal area, must displace a lot of air moving at hwy speeds. Mileage holding steady 21mpg over 6,000 miles and 90% city bal hwy(08 EXL-V6). I've got a trip to the White Mts of New Hampshire planned next week and I've already warned my wife that I'm interested in true hwy mileage so I'll be tanking up entering and exiting the interstate to see what I get, will post results.
