When out o charge does gas engine drive wheels or charge battery which drives wheels?

I see conflicting answers on this question. Some say that when you run out of battery (and driving in normal mode), the gas engine charges the battery, which drives the wheels. Others say the gas engine drives the wheels directly without charging the battery.

Does anyone know for sure?

This is important because if it's the latter, the battery is basically untouched (and thus will have longer life) when in gasoline engine mode.

Watch your power flow indicator below the speedometer. That shows you what the power source condition is at all times. Watch it in hold mode or watch what happens if you engage MM once you've run out of Normal battery.

The engine revs at higher rpm to replenish the battery level over what it takes to sustain your driving speed requirements. The battery is never empty. There is always a small reserve for quick burst acceleration.
