Are Mild Hybrids important to Lynas?, page-6

Quite right and thanks for the correction. (Don't do complex posts when tired!)
I would point out for starters that this is purely energy density and not power to wheels.
The EV setup is much more efficient at doing that conversion!

Corrected Calculations:

Petrol (gasoline) has an energy density of 46 mj/kg (https://energyeducation.ca/encyclopedia/Energy_density)

Now 1 mj = 0.28 kwh ( https://www.google.com/search?client=firefox-b-d&q=convert+mj+to+kwh )

So that’s 46 x .28 = 12.9 kwh/kg petrol energy density.
The tesla battery stores 90kwh equivalent to 90/12.9 = 7 kg of petrol in over half a ton of batteries.

The point's even starker on the corrected numbers.
