BYD Dolphin Standard incentives & grants
Hong Kong ended ALL EV first-registration-tax concessions on 31 Mar 2026 (previously HK$58,500 general / HK$172,500 One-for-One) — every EV price here already includes full marginal FRT (46%–132% brackets). What remains: e-PCs pay a lower annual licence fee (HK$2,114 vs HK$5,074 for a ≤1,500cc petrol car), which IS modeled in the totals. Source: HK Gov P2026022500288 (25 Feb 2026) · TD fee schedule.

What we assume for maintenance
Assumed HK$2,000/yr for an EV at 10,000 km/yr — about HK$10,000 of the 5-year total above. On this market's assumptions an EV runs about HK$2,000/yr less in maintenance than a petrol car (HK$2,000 vs HK$4,000). See the methodology for sources; adjustable in the calculator.
Cost to charge the BYD Dolphin Standard at home
The BYD Dolphin Standard runs about HK$18.66 per 100 km at home — versus about HK$222.88 for a typical 7 L/100km petrol car.
