I figured an EV is worth about 60mpg with a fair comparison to a gas car.

Modern internal-combustion engines have 35% to 40% efficiency, with even efficiencies of over 50% for the very big 2-stroke Diesel engines used in ships.
Nonetheless that remains about half of the efficiency of electric vehicles and the energy efficiency of the latter can be greatly increased over this ratio by the recovery of the kinetic or gravitational energy, when braking or descending.
It propels a car about 10 miles. About 1 mile per kWh
Charging my electric car via AC at 7kW to replace the power used to drive 90 miles in autumn takes 26kWh according to the meter, so 3.5 miles per kWh.
And so on.
P.S. Since I drive a stick, I coast a lot. I live in a hilly area, and have a pretty good feel for just how and where I can shift into neutral and coast. I also coast towards a red light with the goal of reaching the intersection just when it turns green. (Moving forward from a dead stop uses lots of energy.)
Anything with electronic fueling will cut fuel during engine overrun. Staying in gear while coasting uses zero fuel. If you pull the clutch, the engine has to fuel enough to idle instead, which is actually a really inefficient fueling regime.
