BYD sealion 6 first long trip fuel economy

Sharing first long trip fuel economy on our new sealion 6.

Left home on 99% battery. Full tank. Showing 1000km.

SOC set to 60% save. Driving HEV mode. Later decided to charge at Holbrook while having lunch. So change to auto run down battery.

Arrived at Holbrook(about 410 kilometres in) Battery at 26%, petrol showing 453km left

Charged to 97%. Cost $8.37. Keep driving
Quick stop at Yass.

Reached Canberra 16% battery 168km(12%) left in the tank.

Total actual driving would be around 690-700km.

So with one charge the fuel consumption is 7.5/100km overall ? (Not minus the ev range) If consider EV covered 100km or so. Then fuel consumption is 8.8/100km.

How does this look ?
