Same in Germany. Prices can be as high as 75-80 cent/kWh at certain public fast chargers. That would be 16€/100km or more, while a diesel with consumption of 6.5l/100km costs about 13€/100km at current diesel prices.

I was always wondering how people get these 6.5l/100km. Never had that. Diesel Mazda 6 was closer to 8l/100 km, old euro 3 Passat was 7, petrol Golf 4 - 8, BMW 3er no less than 10. In the BMW case it’s 21€/100km and it will be replaced by electric vehicle one day. Apparently electric vehicle needs ~20kWh/100kh and I can choose if I charge at home for ~8€/100km or I go for fast charger for ~16€/100km.

I own both a diesel (2021) BMW SUV and an electric BMW. The diesel has an average of 6.0l/100km since factory. It's slightly higher on highway (~6.5l) and slightly lower on national roads (5.0-5.5l). It's a typical 4 cylinder, 190hp with a 48V micro-hybrid system. I can imagine a 3 series or a non-SUV would have even lower averages.

The electric BMW i4 is averaging around 16.5-17kWh/100km.

Woooow, neighbor’s older X3 consumes 12 liters petrol for 100 km. Looks like renewing car could be economically viable option. i4 is amazing, but not suitable for my needs having only one car in the family.

(not an attack) I would suggest you check how you are driving and maybe try to drive in a more conservative manner (of course terrain/traffic may be the culprit). My recent car usages:

- 2007 Honda Civic (gasoline): 5.9L/100

- 2015 Mazda CX-5 (diesel): 5.6L/100

- 2017 Porche Cayenne S (gasoline): 7.9L/100

- 2017 Lexus IS300h (gasoline + hybrid): 4.9L/100

(Can't remember my older cars consumptions but even those never more than 6L/100)

For reference, I now drive a 2021 Hyundai Kona/Kauai EV. My average is 12kwh/100, though I'm still getting the hang of driving it more efficiently so I'm confident I may get it a bit lower.

Depends on how you drive and how large your car is. My moms old Renault capture diesel uses around 5l/100km on average (combined city/highway) while she is driving and around 5.5-6l/100km while I'm driving. Just rented a Peugeout 208 1l diesel in Nice, France. Averaged 5l/100km during the week (500 km). Around 50/50 split regarding kms driven on highway and inside a city.

I have a 30+ year old Toyota highlux converted to be an RV. Looks like a brick, drives like a boat. But even that thing manages ~10.1l/100km.

Depends how you drive. I had 5.5L with a BWM serie 3 diesel, about 6.1L with a class E wagon diesel. I would consider myself an average driver, neither slow nor fast. Cars in normal mode (not eco, not sport).
