BYD Atto 3 Superior cost to own in Hong Kong — the true 5-year total
The BYD Atto 3 Superior starts at HK$289,680. Over 5 years, owning one (EV) costs about HK$321,739 in Hong Kong as of July 1, 2026 — HK$5,362/month, HK$6.44/km — including depreciation, charging (with the ~12% charging loss most calculators ignore), maintenance, insurance, financing and licence fee. That's HK$36,775 less than a comparable Toyota Corolla Cross HEV over the same 5 years.
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.
