I'm with you on the "not cold enough"
I've had 60 cars and some cars' air con systems are amazingly cold, the MG's is one of the warmer systems.
Better than no air con though
I would agree with that statement.
On previous cars I have owned, if you set the A/C to super cold
when the air flow is directed at the front screen, you can see a small band of condensation / ice forming across the bottom of the wind screen.
The MG does not get THAT cold.
Like others have said, it’s works well on the min setting, but not as cold as some systems I have witnessed.
The Americans have fantastic A/C units in the majority of cars that I have driven over there.
Tinting the windows on the ZS EV - WILL improve the situation, as the factory glass offers no protection from the sun
at all.
If you use the “Recirculation” button, it will help cool down the car more quickly, but it may start to mist the glass after a while.
If you have the sun roof, don’t have it tilted or the side windows cracked open when you have the HVAC running.
I do like to have the sun roof tilted when the weather permits.
It helps change the air in the cabin and preserves the range a little as a bonus.
The HVAC in the ZS EV is a basic A/C unit with NO climate control.
I don’t find that a big problem at all to be fare.
My previous VW Golf had climate control, but I don’t really see any difference to be totally honest.
If you want heat or cool air you just turn the dial, what’s hard about that ?.
Yes - You may have to adjust the settings a little as the weather condition are constantly changing in the U.K.
But these are only a first world problems really.
I do like having actual dials that you can turn to set both temp and fan speed.
All that “Faffing” about in menus on screens to alter the settings is distracting when you are driving and can therefore be unsafe.
I must say AC is the least used function on any car I've ever had, I had a Kia niro before this ZS ev & I never used that once in the three years we had it
