I find that many times when I depress the gas pedal to speed up in EV mode the ICE kicks in.  I expect this if I jam on the pedal to merge onto an interstate but this happens with modest pressure.  Is this just the way it is or is there some sensitivity adjustment possible?

Are you in EV later or Auto mode?  Select the Empower screen on the left side.  How many blue bars of power do you have?

Is it cold, or possibly too hot outside? A cold battery can't provide as much power so the ICE will kick in under lower thresholds. Likewise an overheating battery presents a similar situation (haven't owned mine long enough to encounter that yet)

Cold I see that one, if the HVB is close to empty or its very cold you could drop to 3 1/2 bars at the bottom end (the lowest I've seen), but even at that you still drive "normally" without kicking in the engine.

Putting it in EV Now mode will make the ICE much less likely to kick in.  

 

But there's never any guarantee.

 

Long use of the go pedal like climbing a hill will make it kick on at any temp.

 

In the cold it will definitely kick in sooner. 

And if you're using the heaters, a lot sooner.

If it's cold and you turn on defrost that's almost a guarantee that the ICE will start.

Funny enough I've been using EV Now a lot more lately. On my 2013 it seems to make a few things run a little more 'Eco friendly' in a subtle manner. Climate control for example with heat doesn't seem to run the fan full blast once the coolant is up to usable temp that I used to see running in Auto. Also if defrost is active I do get the message stating the engine is going to be turned on and the EV icon turns yellow but in 30-40 degree temps it hasn't actually done so and the engine has remained off. It has kicked on though at colder temps in that scenario. Usually I only use defrost just long enough to defog the window especially in the handful of really rainy spells we've had here the past month or so.

Yes ^^^  EV now decreases the chance of starting the engine while Auto tells the car to do whatever is necessary to get you what you're asking.  If you ask for heat, it starts the engine to assist the EV heater to warm up the coolant the quickest for example.

I'll run some tests but I am probably running with Auto EV and that's the problem.

You never answered my question, it was asking how many blue bars do you have in auto mode?

 

Just for your information I run in AUTO all the time I never use EV now unless is absolutely necessary and can drive the whole HVB without turning on the engine if I don't want to.

I started out with Auto, but I have to navigate the Concord (MA) traffic circle every day, and the acceleration needed to insert myself into that chaotic flow would start the motor.

 

My commute is well within the EV-only range, so that's my default, with EV-later if I'm going on the highway, which I pretty much only do if the trip will require gas anyway.
