Saab is weird, it has really bad fuel economy in the city ~12L/100km but on the highway it's alright, around 7L/100km which is not great but not far off from modern cars. My wife has to travel about 360km round trip between cities, which with the current fuel prices is at least 50EUR. Same trip with the Tesla costs usually around 3 EUR when charging at home during the cheap hours at night and has never cost more than ~15EUR even during the crazy electricity prices and/or fast charging.
