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 $79,039 for the BMW X3 xDrive20i. That is a $27,226 difference — about $5,445 a year, or $454 a month.

The single biggest swing is depreciation: across 5 years the gap is $13,700. 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 X3 xDrive20i'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.
