BYD Dolphin vs Hyundai i30
Data verified April 2025
At this driving profile, the Hyundai i30 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 Dolphin's higher purchase price doesn't fully pay back through lower running costs within 5 years. The BYD Dolphin costs $77,038 in total versus $59,948 for the Hyundai i30 — a difference of $17,090. 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 Dolphin still avoids around 3,491 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.
