Exactly my point. When you climb a mountain like the Sierras, the EV battery will be used up in 1st 10 minutes for Outlander (and Sonata). Then you will be on ICE only. For the rest of the way, the heavy battery and EV drive train is a liability. That may be a reason why Hyundai used the 6 spd AT. You can at least down shift and use that 154HP I4 at it's peak band.That 117HP is only the combustion engine though. Believe the total HP is 203HP or so when you account for the EV motor. Not saying that's a lot, but it's a lot more than 117 of course. I'd bet the EV torque helps a bit too. Who knows, I'm just glad that another brand is stepping up with something new in a PHEV standard SUV.
Newsflash: all contemporary cars (at least going as far as 2001 models, which my Mitsubishi Galant was back in the day) run AC when you direct air to the windshield, whether you want it or not.You don't use AC to defrost. You need heat to melt ice, not cold air.

There are cases when AC doesn't run if it's too cold, but that's a separate event.
Even if the AC light is off, it will run it. I'm not sure what happens if you turn the AC off while defrosting.
When you defrost the windshield by directing warm air to the windshield, the AC comes on whether you like it or not.You don't use the AC to defrost a windshield. You use AC to demist/defog a windshield. You can also demist/defog a windshield by heating it above the dew point.
Fuel, I am well aware of how an AC system works. I worked as a test tech for a small AC/heater manufacture for large trucks and off-road equipment for over 10 years.Marshall you are missing the fundamentals of refrigeration systems. Believe me, I live in that world.
An AC in cooling mode not only cools the interior by exchanging heat with the exterior air.
The refrigerant is compressed, changes phase from vapor to liquid in the condenser.
During the cooling phase, the high pressure liquid is throttled by a cap tube or a txv into low pressure vapor in the evaporator in the cabin. That phase crhange process absorbs a tremendous amount of heat, thus cooling take place.
While cooling the cabin air, AC also condenses the water vapor in the air into liquid and it drips out of the cabin.
A heat pump is the AC run backwards, by the use of a reversing valve.
There is no defrost when the system is in heat mode. There is also a need to stop the heat pump every half hours or so to DEFROST the heat exchanger that will be caked in ice.
In humid climates, a form of AC is used as dehumidifier, it will even dry your carpet in the house.
Well, warmed air just keeps the water droplets suspended, it is never is removed.
So when this warmed air hits the windshield which is very cold, it fogs up the windshield.
I learned this when I was a poor college kid driving a '66 VW air cooled engine with long "heated air exchanger" ducts. I
t was useless. My handy wiping rag was always at hand.
The heat pump is based heat exchange to the ambient air. Guess what when the ambient air is -30F, not much heat is exchanged.
BTW, look for Redstrawberry's thread on inadequate heating from a covered gasoline engine.
Heat pump will not work in the northern hemi, and is not needed at CA, TX and below, Asia, S. Amer, where Hyundai sells cars.
