Byd Sealion 6 Premium enquiry

Hi, I have some general inquiries about the Sealion 6, particularly for use on Canberra Road.

I typically drive 40 km to work on roads with speed limits of 80 to 100 km/h. Will the Sealion 6's EV mode allow me to drive the full 40 km at speeds of 80 to 100 km/h?

Could you also explain how the EV mode works?
