Honda Accord VCM
Just picked up my new 08 Accord EXL-V6 with Navi etc Sat. This is my 6th Accord. Ok so I get the whole "gogreenloweremissionssavefuel gig". But here is what noone is talking about yet and so far, I appear to be the first..... VCM (Variable Cylinder Management) Hondas new generation engine for the Accord is different then engine they have been using in the Odyssey. Ya see in the Van version Honda implemented a 6 cylinder to 3 cylinder VCM function. in the 08 Accords its 6-4-3. The issue is this... when you are in the city you will rarely notice anything, maybe when the "ECO" light comes on you may feel a slight hesitation a 1/2 second after but, overall with all the stopping and starting etc you cant seem to notice anything out of the ordinary. Ok so here is the rub,,, take it out on the highway and run the car at about 65-70 miles per hour (normal within the speed limit) cruising and you will begin to feel the VCM system trying to figure out what it wants to be when it grows up... you "may" feel the car surging and slight hints of hesitation as it jumps from 6-4-3 cylinders.. those of you that like to feel the road and are "in tune" with your ride "may" just get frustrated. Add on top of that the new "Grade-Logic" system and what you end up with is a a car that can (at times), feel like its trying to get into gear (at least mine anyway). This seems to be minimized when in "cruise control". I found this hesitation and/or surging felling no matter how stable I kept my foot on the gas, even going so far as to lock my ankle in one position thinking the gas pedal may just be super sensitive. I took it into the dealer today and they ran about every computer test they had on it and all was ok (or at least within specs). in fact we road tested two other V6's and sure enough... same drill. So caveat emptor (buyer beware) the car is awesome in almost every respect BUT just be sure that you know what you're buying and how it operates. It is different than your run of the mill V6 engine. Yes its a new technology and yes I drove a standard V6 for years, so I need to get used to this, and (of course) I am sure I will, ( well a pray I will after dropping $30K)... but if you are concerned that yours is having issues or that it is not running correctly... it most likely is (as designed). My salesman had me believe that the only thing you I would notice is the "ECO" light coming on and that just isn't the case in my experience.
