Oops, I meant the automatic has 5 speeds. The manual has 6.
 
VCM stands for Variable Cylinder Management. Essentially it shuts off either 2 or 3 of the 6 cylinders when you are cruising at highway speeds in order to save gas. Some people have complained about the roughness and others don't notice. There's a whole forum around here about it.

Oh, is that the same tech that was used years ago in the 3.5 V6 that was an optional engine I believe in the Ody van? They claimed about 3 or 4 mpg better.
Or is VCM brand new?
 
Sounds like what they did with Dodge V8's a few years ago.
 
I guess they have perfected it since the old 8-6-4 in the Cadillac's eh? They were a disaster. I guess with today's electronics they can shut of the fuel injectors to the non firing cylinders, and not have the cyl walls washed down with gas.

Perfected? Depends on who you ask. Some Accord owners aren't fans.
Honda Accord VCM
 
I have no personal experience with this technology - just observing what others are posting.

Yeah, same principal that GM used.
 
And yes, they use that in the Ody and now the Pilot too. The Accord Crosstour also has it... but alas, the Crosstour has no manual available.

to be honest, Kirstie, I'm just not that surprised. I was hoping to give them (Honda, and I wonder.. but probably Dodge also?) the assumed benefit of the doubt as technology progresses. I guess we can deduce (rightfully so) that some things shouldn't be messed with.
 
The whole principle of shutting off cylinders that are still connected to (and prone to the exact same reciprocating mass, less a power-stroke) the same crankshaft, I have never really been onboard with, no matter how optimistic I have tried to be about the prospects.
Just goes to show..trust your instincts..

You know, my bias towards my confidence in Honda as an engine builder, does get questioned from time-to-time. And this is a perfect example.
 
Another, is my (presently still owned and used but not without some serious internal bits attention) 5 hp Honda snowblower. The governor failed (due to a very cheap plastic {actually nylon, but with not enough pork} gear on the very inside of the engine to control the governor. Briggs has perfected that very same governor operation but instead, with a super cheap but effective external, wind-vane governor control. So a person might reflect on this as an over-engineered and complex governor.
"Mr.Honda...you aren't always the perfect engine designer/builder. Don't rest on your laurels just yet. As consumers, (some of us) are watching what you screw up".
 
But lest I get accused of getting on their case too much, I'll add that the engine in my CRV is so smooooth, that if, at times, I have the tunes very loud, sometimes it takes me a few minutes to realize that I forgot to upshift to 5th from 4th as I made my way from a 30 to 35 to 50 mph zone. That's an impressive compliment in case anyone was not sure why I mentioned it..

I've had that exact thing happen to me in my 06 Accord. My 95 was much noisier and I could easily hear the engine.

I think they are the same engine aren't they? 04, 05 and 06's. Might be tuned slightly different. Mine is 2354cc 160 hp at 6000 rpm 162 lb-ft at 3600 rpm and CR of 9.6:1. If I were to guess, I'd say in the Accord they might have bumped hp a bit and maybe lost a few lb-ft torque, or if not, then peak is likely above 4000 rpm.
 
Technically though, no two engines come off the assembly line in exactly the same perfect balance. One can extra buttery smooth, and the other one beside it not so much. That becomes more evident if the engine design is a bit raspy to begin with, except non are ever buttery smooth.. (GM's Quad 4, Ford's old 2.3, Chrysler's well...many of their 4's) etc

You pretty much nailed it... It's the 2354cc i-VTEC engine.
 
Same displacement but HP is 1665800 and Torque is 1604000. Compression Ration is 9.7:1.
 
I absolutely love this car.

An impressive and comprehensive list (including a few mentioned later).
Will it convert those who will not be converted? Probably not. Their loss.
I doubt that was your intention though anyway in this day and age.
 
Still, it is cool to see the stick faithful here.
