That's because petrol has ~20 times more energy per KG than Lithium Ion cells, and engines are only ~30% efficient at converting it into movement (vs electric motors at 90%). There's more potential for various optimization in an internal combustion engine. EVs have been designed from the get go with most of the possible software optimizations...
