Bmw 225xe Iperformance Maintenance Cost 2024 Review. The average fuel consumption for the trip was about 97mpg, so i probably used about 1.3 litres of petrol for the trip, plus about 6kwh of electricity. Still, it’s cheaper than buying a new car to do maintenance & repairs and if you take care of your bmw it will last a long time.

That would cost me about. The average fuel consumption for the trip was about 97mpg, so i probably used about 1.3 litres of petrol for the trip, plus about 6kwh of electricity.
