By the way, for those who can't quite make it out, the ECO light in the Accord is the dim thing just below the 8 in the tachometer, not the bright green thing between the gauges (that's the D indicator). Face it, the Accord is one of the LEAST distracting models out there.
It's amazing how using a smaller scale for the Honda makes the other offerings look so much larger. So, how long have you worked for Honda?

It's the first pic that I found when I googled; no need to be snide. Below is yet another photo, showing the smaller-font, dimmer than the PRND321 or Odometer, ECO light.
I'll pass on responding to the personally-directed comments. Others should follow suit. My sincere apologies, it appears the Fusion's picture wasn't the same size as the others either.

mrmack90, Grade Logic has been on all Honda's and Acura's since the mid-90's at least. It can be a little disconcerting and weird at first, but you do get used to it. Once you become accustomed to it, your driving style will anticipate it without thinking. Now when I drive a non-Honda vehicle, I find I have to adjust to not having Grade Logic, meaning I have brake differently in stop/go traffic or when approaching a stop light.

This was the exactly the problem (the most significant one, at any rate) I had with my 08 V6 Accord before I got rid of it. To this day I don't know whether it was purely the grade logic or some combination of the grade logic and the VCM. In any event, when I had my first regular service done (~ 6,500 miles), I asked the dealer's service dep't to look at it, and they applied a software update. That helped the issue considerably, though did not entirely eliminate it.

Honda engineering just finished looking at my 2008 Accord V6 and concluded that the droning noise, vibration, and sluggishness caused by the engine operating in 3 cylinder mode "is a normal characteristic of this make/model". If you're considering acquiring an Accord with VCM and are accustomed to the quiet smooth running engine in the previous generation of Accords, you will be annoyed by the VCM engine.
For me, I just filed papers for arbitration.

While it can be noticeable at times, I really like the VCM's fuel mileage... I had an 08 EX 4 cylinder that got around 20-22mpg consistently, and my new 09 EXL V6 gets similar mileage with allot more ooomph. Im sure as Honda improves this technology it will become even more seamless to the point where it really isn't noticed.

The VCM's fuel mileage is not so great. In looking at the new consumer reports, they mention that the gas mileage on the VCM equipped models is a negative (not to mention that this model is now the lowest rated Accord by consumer reports in the last ten years). The new Ford Fusion is rated higher than the Accord for reliability, customer satisfaction, and cost (since the overall mpg for the Accord is lower that the previous Honda Accord V6). My 2003 Honda Accord V6 got between 26 and 30 mpg without any noise, vibration, or surging. Honda needs to go back to the drawing board on this one.

Hi everybody. I plan to test drive an Accord V6 this month. I hope the VCM is not a deal killer. really like the look inside out over the Camry. And Accord has double wishbone suspension. I missed it last 20 years.
At what speed does the VCM kick in ? Honda brochure only mention low cruising speed for 3 and high cruising for 4 cylinder. Does it kick in in city driving? Lots of acceleration to 45mph then brake to stop driving. On the highway I can maintain speed of 60 mph without much variation. Houston is all flat.

I would inform the salesman of my concerns, and let him know I want to do an EXTENSIVE TEST DRIVE, at various speeds (from 30mph to interstate speeds). Make sure you test drive THE car you plan to purchase, and not assume each car will be the same.

During any driving situation VCM activity is in direct proportion to input and backing off on the throttle. The sensation felt is sometimes more evident as you slowly depress the throttle causing the 3 or 4 cyl mode of operation to switch to full 6 cyl power, but not if you aggressively engage the throttle. The schizophrenic nature of the design can be felt on a regular basis as the on again off again relationship your foot will have with the throttle during typical city driving. In my particular car it seldom is any more noticeable than a transmission shift. 21 months and almost as many miles of motoring with VCM as my constant companion and it would not deter me from buying an Accord again. Just seems that the rest of the mfg's have achieved the same results in fuel economy by going the traditional route of adding another cog to the tranny.
