BEV vs Petrol costs

I used to run an Audi Q7. I collected data over 3 years and 60,000 miles.

I new run an Audi e tron. I have collected data over 2 years and 40,000 miles.

Over this time, diesel costs and electricity costs have varied.

I have worked out how much this has all cost me and I want to keep a reference here.
