Converting between the electrical energy and the heat energy intrinsic to gas is the wrong way to do that calculation. You need to compare efficiency vs efficiency to get a proper price comparison, as the heat energy of gasoline is much higher than the actual energy used to move a vehicle. Most is wasted.
A decently efficient EV is about 250Wh/mi (it’s closer to 220, but 250 makes math easy), so 105 EU of power can travel approximately 4000mi.
By comparison a decently efficient ICE (in Europe) gets about 5L/100km, roughly. So, to travel 6430km (4k miles) you’d need about 320L of fuel. At 1.75EU/L that would cost 560 EU.
It’s a very substantial difference, assuming your pricing is correct on fuel and energy cost.
