Ok I only put this in for mainly what it says underneath.
Now its says underneath that only 70% of the 12kWhh HV battery in the Phev is used . 12 x 0.7 = 8.4
So there is only 8.4kWh usable in the High Voltage (HV) drive battery.
Notice the top right side of the image where it shows 8.6 x 8.4 = 73km (8.6km/kWh from red box on display x 8.4kWh usable HV battery capacity gives 72.24km) in ev mode.
If only I could get those figures.
...... I am still laughing.
It also says if we can get 17kWh/100km or less in the display where the red box is we should get about 50km or more in ev mode.
Around town where I live (60kph speed limit) when the traffic is light (very few red lights) I can get about 50kms.
