Using common sense, without overcomplicating things:
A 430 hp engine at full throttle consumes about 130 liters of gasoline per hour.
An electric motor drawing 360 kW will, in one hour, consume 360 kWh of electricity.

Since a 430 hp gasoline engine is roughly equivalent in power to a 360 kW electric motor, it’s clear that comparing 130 liters of fuel to a 360 kWh battery is entirely reasonable.

There’s no need to calculate thermal efficiency or other engine losses here, because all the necessary information is already in the basic data.

A gasoline engine is actually even more efficient in practice, because such a setup has a lower overall mass.

Yes how ever we calculate it, but 10 gallon fuel powering a V8 would equal 100 kWh battery electric power is easy to remember and would be not so wrong.

Plavutka are you actually German as well?

No, but I have some business partners there, and I’m there a few times a month, mostly in Bavaria.
