True, but note that the vast majority of the time (or at least on
the wimpy EPA certification cycles!) very little of that 240 hp is
actually used. To be sure, the Accord is a lot heavier and less
aerodynamic than the Insight. So it would benefit from a bigger
battery. But (as you no doubt know) the proportion of battery to
ICE size doesn't need stay the same as ICE power goes ballistic.

It seems to be exactly the same as the Civic, almost the same as the
original Insight, and completely different from the Prius and Escape.
The point about the motor being tiny is true, though. The benefit from
idle-stop is still there, as is the cleanliness of the engine at initial
takeoff, where the ICE wouldn't normally be very efficient.
The Accord IMA produces 12% more hp than the Civic.

I don't think it would affect the balancer at all. On the other hand,
there wouldn't be a flywheel, since the IMA is effectively the flywheel.
That would help smoothness at idle.
Engine RPM when blipping the throttle could be part "drive by wire".
There's a lot of computerized engine control involved. The Civic still has
a throttle cable. I don't know about the Accord. The Ford Escape does
not. In the Ford, blipping the throttle does absolutley nothing unless you
go beyond about 2/3 throttle, at which point the RPM climbs rather slowly,
maybe 2 seconds to 3000 RPM.
It could also be the heavy flywheel affect of the IMA.
