Which is cheaper to run?
Over 5 years of average Australian driving (15,000 km/year in NSW), the BYD Seal costs $51,813 to own and run, against $70,795 for the BMW 320i. That is a $18,982 difference — about $3,796 a year, or $316 a month.
The single biggest swing is energy / fuel: across 5 years the gap is $9,332. Energy is where electric cars usually win — charging at home (especially on solar or off-peak rates) costs a fraction of petrol per kilometre — while the BMW 320i's higher purchase price can narrow the gap through depreciation.
Estimates use average NSW electricity and fuel prices, typical insurance and servicing for this segment, and a 5-year depreciation model. Your numbers will vary with tariffs, driving style and resale values — use the calculator above for a tailored figure.
