BYD Atto 3 Extended Range vs Hyundai Avante 1.6 GDI HEV SR: 5-year cost to own (Singapore)

By Ivan H., EVCostIQ · reviewed against our public methodology · every source dated on this page

Over 5 years in Singapore (17,500 km/yr), as of August 6, 2026, the BYD Atto 3 Extended Range is cheaper — about S$126,567 over 5 years vs S$128,622 for the Hyundai Avante 1.6 GDI HEV SR, a S$2,055 difference. In Singapore the EV usually wins on running cost (cheap electricity vs S$3.42/L petrol) while COE dominates both cars — we say so plainly.

COE is set by a biweekly auction and swings thousands of dollars — every figure here uses the S$124,790 (Cat A) / S$126,236 (Cat B) COE assumption. Confirm the current COE before you commit; it is the single biggest line in the price. Source: LTA registration-cost sheet, 2026-08-06.

EV Early Adoption Incentive: the EEAI (45% off ARF, capped S$7,500) is baked into the EV figures for 2026 registrations — and it sunsets 31 Dec 2026. Register a BEV from 2027 and it costs more. Source: LTA.

Electricity vs petrol — and why COE still rules

On running cost the BYD Atto 3 Extended Range is far cheaper — about S$5,410 of electricity over 5 years vs S$14,065 of petrol for the Hyundai Avante 1.6 GDI HEV SR (S$3.42/L is dear). But COE + ARF dominate both cars — around S$125,891 on the EV and S$151,738 on the petrol car — so the 5-year winner is decided mostly by price with COE and how much you recover at de-registration.

Where the money really goes — COE + ARF dwarf the fuel

The registered price with COE for the BYD Atto 3 Extended Range is S$171,888. COE + ARF alone are S$125,891 of that — many multiples of the electricity or petrol you'll ever buy. That is the honest story of Singapore car cost.

COE (quota licence): S$124,790biweekly auction · dominates the price
ARF (net of VES / EEAI): S$1,101gross S$31,101 − VES rebate S$22,500 − EEAI S$7,500
OMV (open-market value): S$27,929declared import value

Recovered at de-registration (yr 5): S$84,888unused COE S$62,395 + PARF S$330 + residual value S$22,163

How depreciation works here: it is the registered "price with COE" minus what you get back at de-registration — the unused COE (rebatable over the 10-year licence), the PARF rebate (a capped % of ARF paid), and the car's remaining market value. Where a published Singapore depreciation figure exists (PaperValue / sgCarMart), we use it — the straight-line S$/yr buyers actually quote. That is why the S$100k+ upfront, not electricity or petrol, dominates the 5-year total. What you'd get back at deregistration (official PARF + COE rebate) →
