Decreasing Range of MG4

[decrep]

That one yes but its a rare event. Old dog trying new tricks doesn't work that often

tell me about it!!!!

Something off with those figures? Overall (real world) consumption higher in 77 to be expected due to weight, but for the WLTP breakdown figures, the 51 has the highest consumption.

WLTP is from the manufacturer. Perhaps the LFP battery consumes more energy in WLTP testing (e.g. for cold weather numbers as LFP loses more capacity than NMC in cold conditions)?

The 51 is only 16 kg lighter than the 64.

Another factor would be the higher AC charging efficiency of the 77, being 3-phase 11 kW.

WLTP testing is based on AC charger energy throughput and 11 kW 3-phase is more efficient than single phase charging.

Maybe MG is slightly underselling the WLTP on the 51 so it looks like the LFP battery holds on to the official figure for longer? It would surprise me if they think that much about it, but who knows.

I did this drive yesterday in my 64 kWh MG4:

About 3/5ths on the dual carriageway, the rest on pretty ordinary country roads. Started out on wet roads and cool, not cold.

I had a tow bar bike carrier rack and bike on the back.

On that trip, you could have covered 658.5kms before the range dropped to 0 and the SOC showed 0%, maybe even 700kms before it actually refused to proceed, that's more than double the GOM believes our MG4 51 would get .....
Yet, the 17.3kwh/100kms doesn't work out to anything like that, 370kms roughly at that rate of consumption ..... why don't the figures add up?

was the km reset at fill up?

I left with 100% and charged twice enroute. I never said it was a drive without charging.

I was sharing the car's consumption on a long trip with a bike rack and bike on the back + full boot of luggage and two occupants. The economy rate was barely any different to normal.

Might have been clearer, if you had stated how much was added enroute.

That seems pretty good mileage fully loaded. Hoping to get a better idea with mine when I travel to Shellharbour this week and use fast chargers for the first time

Say hello for us, to the area we left to move to South Australia. If you come through the steelworks and Warrawong and the Primbee raceway, you will travel across the Lake Illawarra bridge from Windang to the suburb of Lake Illawarra, that was where we lived, quite a feeling of moving from the burden of working life to being on holidays each time I crossed that bridge ......
Share some photos of the area, it is quite a scenic spot, so close to the biggest steel manufacturing plant in Australia

The pertinent data I was sharing was the trip total consumption of 17.3 kWh/100km.

But since you asked:
Stop 1: 20.133 kWh
Stop 2: 37.336 kWh

Yes it's beautiful. Windang is one of my favourite spots to wave sail

Thanks for confirming that. It was what I'd planned to do. As much as I don't like the company's master, the other choices aren't great.
