It appears that when you start up the C-Max it defaults to EV Auto mode.  Is that correct?  If so, is there a way to make the default mode EV Now?  Most of my driving is around town and I want to control when the gas engine kicks in.  It somehow gets in EV Auto mode and the slightest acceleration will cause the engine to start.

If you put it in EV Now mode,I believe it should stay there until you run out of battery and get dropped into hybrid mode.  

 

That said, depending on conditions, the gas engine can still fire up while in EV mode.  And yes, in the winter it can be a lot more likely to fire up in Auto mode. 

 

The biggest factor is Defrost.  If you turn on the defrost in any way the car is VERY likely to fire up the gas engine.  

Next up is the heater in general and/or outside temp difference.  The larger the difference there, the more likely for the gas engine to fire up.

 

But no, to answer your actual question, there's no way to get Max to default to EV Now mode.

"It somehow gets in EV Auto mode and the slightest acceleration will cause the engine to start."

 

That shouldn't be the case at all, you should have at least 3.25 bars when its bitter cold/battery cold, and closer to 4 bars of power all other times.  Your accelerations should be more than sufficient up to 2 bars, from 0 to 30mph, as you get faster to feel like you're accelerating you could possibly use more than 2 bars and that's probably why you are kicking in the engine but if you are driving the battery that hard I would not recommend it, not a good idea for its long life in general.  

 

This is all assuming you are not using electric heat, if you are that adds an extra bar of power on top of everything making it much harder on the battery and easier to reach its limit and start the engine.

My car is always in EV Now mode, as I drive it as an EV. Now that's not to say that in the winter if you turn the defroster on anything higher than Low temp then the engine will spin up to provide heat for this.

If I've stopped in EV Later, it starts up in Auto.  It sticks in EV Now.

 

If you turn on the floor and then the defrost vents, the motor is less likely to start.

 

Also, if you're in Low gear with a full battery, the ICE will start the first time you slow down.  I have to drive a block or two before shifting into L.

Thanks for all the insight.  I am not using the heat or defrost. Based on the responses, I am assuming that even if the Max is in EV Now, it still might kick in the ICE if you punch it.  I am pretty careful not to really punch it but that seems to be the only explanation.

It shouldn't normally...  If you have it in EV Now and aren't using heat/defrost at all, then the only time I've had it kick on under those conditions is along the lines of drawing 3.5+ bars worth of power for at least a couple minutes(like climbing a good hill or some highway speeds...)
