My Kona didn’t have a heat pump and I didn’t miss it tbh.
My scenic etech has it and I’d miss it.
The scenic etech does more miles but has a bigger battery so don’t know the effect of the heat pump on the range. What it does do is give nearly instant heat, within about 40 seconds I’m feeling heat when in the car, so much so that I’ve not been preconditioning as often as I did in the Kona.
That said I would not pay for it.
Ps the Kona seemed to take an age to heat up so I’m presuming it’s the heat pump in the scenic doing it.
