- COE Categories: Category A includes EVs up to 110 kW (147 hp); Category B applies to EVs exceeding 110 kW.
- Government Incentives: Up to $25,000 rebate under Vehicular Emissions Scheme (VES Band A1) plus the EV Early Adoption Incentive (EEAI).
- Fuel Savings: Electricity charging averages $0.55 to $0.70/kWh, yielding 50% to 65% cost savings compared to RON 95 petrol per 1,000 km.
- Road Tax: EVs incur standard engine power road tax plus an additional lump-sum tax component to offset fuel excise loss.
1. Singapore's Green Plan 2030 & The EV Push
Under the Singapore Green Plan 2030, the Land Transport Authority (LTA) aims to phase out internal combustion engine (ICE) petrol and diesel vehicles by 2040, targeting 100% cleaner-energy vehicle registrations by 2030. To accelerate adoption, the Singapore Government has introduced substantial financial incentives, tax deductions, and an expansive public charging rollout across all 24 HDB towns and commercial shopping centres.
2. COE Categorization: Category A vs. Category B for EVs
Unlike conventional petrol cars categorized by engine displacement (below or above 1,600 cc), electric vehicles are categorized purely by maximum electric motor power output:
| COE Category | Electric Motor Power Threshold | Popular EV Models In Category | Buyer Cost Implication |
|---|---|---|---|
| Category A | Maximum output up to 110 kW (147 bhp) | BYD Atto 3 (100kW), BYD Dolphin (100kW), Hyundai Ioniq 5 (100kW), ORA Good Cat (105kW), MG4 (99kW) | Eligible for Category A COE premiums (typically $15,000 to $25,000 lower than Category B), significantly lowering entry purchase price. |
| Category B | Maximum output exceeding 110 kW (147 bhp) | Tesla Model 3 / Model Y, Polestar 2, BMW i4 / iX3, Mercedes-Benz EQB / EQE, Porsche Taycan | Requires Category B COE, attracting higher premiums suited for high-performance and dual-motor all-wheel-drive configurations. |
3. Financial Incentives: VES Rebates & EEAI
When registering a new electric passenger car, buyers benefit from dual tax relief schemes that substantially offset the Additional Registration Fee (ARF):
- Vehicular Emissions Scheme (VES Band A1): Zero-emissions battery electric vehicles qualify for the top Band A1 rebate of up to $25,000, deducted directly from the vehicle's payable ARF.
- EV Early Adoption Incentive (EEAI): Provides an additional rebate of 45% off the ARF, capped at a maximum of $15,000 to $20,000 depending on the prevailing registration tax policy year.
- Preferential ARF (PARF) Floor: Note that Singapore enforces a minimum ARF floor (historically $0 to $8,000), ensuring that rebates cannot reduce the total payable tax below the statutory threshold.
4. EV Road Tax Structure & The Additional Lump-Sum Tax
Because electric vehicles do not consume petrol or diesel, they do not contribute to government fuel excise duties. To ensure revenue neutrality for road maintenance, Singapore assesses EV road tax through a dual-component formula:
- Base Road Tax: Calculated on the maximum motor power rating (in kW).
- Additional Lump-Sum Tax: Fixed annual surcharge phased in between $200 and $700 annually, depending on vehicle classification.
- Bottom Line: High-performance luxury EVs (e.g., dual-motor 300 kW+ sports sedans) incur considerably higher annual road tax ($3,000 to $5,000+ per year) compared to modest 100 kW family crossovers ($1,000 to $1,400 per year).
5. Running Cost Comparison: EV vs. Petrol vs. Hybrid
Assuming an average Singapore commuter driving 15,000 km annually:
| Vehicle Powertrain | Energy Consumption | Fuel / Tariff Cost | Annual Energy Expense | Annual Maintenance |
|---|---|---|---|---|
| Electric Vehicle (EV) | 15 kWh / 100 km | $0.60 per kWh (Blended AC/DC) | ~$1,350 | $300 – $600 (No oil filters, brake pad savings from regenerative braking) |
| Petrol Hybrid (HEV) | 4.5 Litres / 100 km | $2.80 per Litre (RON 95 after discount) | ~$1,890 | $700 – $1,200 (Engine oil, spark plugs, filters) |
| Pure Petrol ICE Car | 7.8 Litres / 100 km | $2.80 per Litre (RON 95 after discount) | ~$3,276 | $1,000 – $1,800 (Full mechanical servicing) |
6. EV Buyer Checklist Before Placing a Deposit
💡 SingaNow EV Ownership Tips
- Verify Charging Infrastructure at Home: If you reside in an HDB flat, check SingaNow's EV Charging Points directory to verify how many 7.4kW/22kW AC chargers operate in your nearest multi-storey car park.
- Battery Warranty Standards: Most reputable manufacturers provide 8 years or 160,000 km battery health warranties (guaranteeing minimum 70% state of health).
- Beware of Charging Idle Fees: Always unplug and move your car once charging completes to avoid idle fee penalties ($0.50 to $1.00 per minute) levied by Tesla, Charge+, and SP Mobility.
