Nice 4.8m/kWh driving to work this morning going to try and get 5m/kWh on the way home but may have to have the Aircon on
A/C on ?????? …… That is going to be a bit of a tight squeeze !.going to try and get 5m/kWh on the way home but may have to have the Aircon on
A/C is not as spiteful as using the cabin heater, that’s 100% for sure !.I have found Aircon to make virtually no difference to consumption. I have just journeyed home 280 miles all motorway and dual carriageway.
Just after setting off I switched aircon on, it would have been unbearable without, I had tried for a few minutes. It immediately took 10 miles off the GOM.
As I arrived back in Leeds and into traffic I chose to have the windows open and turned off the Aircon, it gave me back 4 miles, so cost of aircon over 280 miles was 6 miles on the GOM and journey completed at 4.3m/kWh.
I had done the outward journey, identical route but in reverse with no Aircon as weather was cooler and car was fine without it and achieved the same m/kWh.
NB it must make a difference somewhere after all you get nothing for free but I'm not noticing anything dramatic or that makes me think twice about putting it on when needed.
Simple quick test to roughly calculate the greedier of the two items, with regards to eating range !.I would guess peak load for the AC system is around 3kw on either heating or cooling. Once cabin temp is stable I can't see it using more than a kw/hr average so in reality, probably less than 10% power drain compared with driving.
Motorway driving will be averaging around 20-30kw at any one time based on what my ampera used to show on the dash. Haven't worked out the Mg5 yet as it's in amps and volts where the ampera used to show power draw in kW.
