Dan, I figure you *really* want to know this ..

You used 7.94 gallons of gas. Multiplied by 33.4 kWh/gallon, gives 265 kWh.

The car required much less, but only about 35% of the energy was converted to mechanical work.

2004."

With a CVT I'd say 2200-2400 RPMS for 60mph. Thats if memory serves me today.

04 5speed @ 60 mph I turn 2150 or there abouts. yeah it might go with 2 cyl. but don't turn that A/C on or go over a overpass, I check it out this AM on the way to work and he's pretty much right the assist does come on but 3/4 up the overpass the assist stops.
Now at one time we had a 1983 Honda civic 1300FE no assist and we drove it like well a car and had no problems going up a hill or passing yeah it might have been a little underpowered but we got like 38 -45 mpg if my memory serves me right and that was with a/c. I do not remember the HP on it. Kevin

My CVT seems to be exactly the same, 2150 @ 60mph. I suppose the top gear ratio on the CVT is the same as on the 5-speed (likely because that's the highest ratio that would be feasible given the available torque)

It seems to me that setting up a lean-burn fuel mode would be a better approach than trying to shut off cylinders on such a small engine, that way it wouldn't necessarily have to be half the power, the engine could inject perhaps 2/3rds the normal amount of fuel for crusing. That woudl still be a pertty substantial savings over a long trip. The IMA algorithm could then be set up to try assisting to a certain degree first before exiting lean burn mode as well, up to a certain max level of assist, or a minimum battery state-of-charge, for getting over overpasses and such.

Question and a comment (comment first): with a CVT the gear could be watever the car desires so it could spin the engine a bit faster to produce enough power. Now the question: whats more efficient, 2 cylinders spinning faster and draggin 2 other cylinders around to produce x hp or 4 cylinders producing x hp? I think the second, the losses of dragging 2 cylinders wouldnt be worth it, the car could always switch into lean burn for those periods of low load, or even fuel cut.

When I drove the Civic Hybrid Manual, and I approached slight slopes on the interstate, the car would slow down from lack of power. (Same thing my insight does.) That's with all 4 cylinders firing. The engine is already as small as it can be.



Oh never mind. I know I'm right, that a two-cylinder civic is not enough power to maintain 60mph, but I don't know how to convince anybody. (shrug) I give up.

I didn't cast a blind eye. I just didn't see that suggestion. Calm down Delta.



Yeah, Honda could do that. They could double the current 85hp engine to 170hp, and enable a 2-cylinder mode for cruising. ----- But the economy would suffer. You'd probably only get 40mpg (same as the HX), not the 50mpg of the current civic hybrid.
