American gas prices are insanely low, and not really representative of the rest of the world. cries in 1.5€/litre (about 5.7€/gallon)
My EV consumes around 15kW/100km, which by cost is equivalent of around 2 litres per 100km (117MPG)

Oh wow, 11kWh to go 26 miles... I guess it depends heavily on the car, then. The Tesla Model 3 (the car I own) gets a little better than 4 miles per kWh, which would mean the trip would take around 6kWh — so about half the cost, making it cheaper than gas even at California electricity prices.

Well that commute includes going up a 2000ft mountain pass so that part drains the battery pretty quick.
I'm sure the Fiat would get better range in flat land, but there isn't much flat land around here.

Going uphill would also burn more gas though, so I'm surprised a pure gas car was getting 36 mpg under that scenario. And at least the electric car would regenerate a portion of the electricity on the way back down; it's not like brakes can produce gasoline, after all.
Maybe.
When I was commuting, my daily driver gas car got 36 MPG. My commute used 0.72 gallons. At $3.55/gallon, the trip cost $2.56 or about 9.9 cents/mile.
At the same time I had a Fiat 500e. The same commute consumed 11kWh.
So the breakeven point (between my two cars) is $0.24/kWh in electric cost.
Looking at my PG&E bill, peak time (4pm-9pm) cost is $0.35/kWh and part-peak (9pm-midnight) is $0.34/kWh. These are winter time prices, they are much higher in the summer (but I only have my current bill handy).
So if I had to ever charge the electric car during peak or part-peak times, it is quite a bit more expensive than gas.
Now, of course, I only charge it at night (PG&E price $0.17/kWh) so it is a bit cheaper. Just need to be careful to set the timer so charging never starts before midnight.
