A modern gasoline engine is about 35% efficient in terms of taking the BTUs in the gasoline and turning it into movement.

0.6 * 0.95 * 0.75 * 0.9 = 38.5% efficient for the EV assuming the best case

So, for the electric you are figuring from the power plant to the wheels, but for ICE it is only from the fuel tank to the wheels. Do you also need to add in the distribution cost of the fuel from the refinery to the tank to be apples to apples? I know it is small, but should be added as well.

I think too many are getting hung up on the point in time efficiency of the EV. The amount of energy to drive a specific mile compared to ICE is almost always better. But how much energy is required to deliver the car to that starting point, including build, storage, overhead and how much energy is required to dispose of the car once it is complete. Those need to be figured into each mile as well.

The EV craze is very similar to the current pandemic. It really isn't about moving from ICE to EV, it is about pushing the self driving, autonomous, not really yours, car. But they can't sell that part, they need to use the EV part, not all the stuff that removes your control over your ability to travel by car.
