The heat portion is markedly more efficient than the 2011 / 2012 /2013 S forward heater.
A lot better down to 15 F. Some better down to 4 F.
No better below 4 F.
But the design is a compromise and the AC is less efficient.
Could have been as efficient but would have required a high precision refrigerant control valve like the home mini-split units use.
But the valve is extremely expensive so Nissan hybrid HVAC has less efficient AC.
The power for AC is very low.
You hardly notice any range impact on non-hybrid.
Might notice some with hybrid.
But still pretty small.
Someone needs to quantify the kW difference but I have not seen that.
