Data verified April 2025
At this driving profile, the Mazda CX-5 is the more economical choice over 5 years in New South Wales.
Running only 15,000 km per year in New South Wales, the BYD Sealion 7's higher purchase price doesn't fully pay back through lower running costs within 5 years. The BYD Sealion 7 costs $103,859 in total versus $77,473 for the Mazda CX-5 — a difference of $26,386. The numbers don't reach break-even within this holding period. If you drive significantly more km per year, or if petrol prices rise substantially, this comparison would shift. The BYD Sealion 7 still avoids around 3,391 kg of CO₂ over the ownership period.
The economics don't stack up at this driving distance — increase annual km or extend the holding period to change the picture.
