Short answer: Yes, the BYD Atto 3 saves me about $2,900 a year in real operating costs compared to my old hatchback petrol car in Singapore – even with EVs attracting higher road tax here.
I have been driving the BYD Atto 3 for 8 months now. So I decided to put pen to paper (or spreadsheet) and compare real numbers against my old petrol hatchback. No manufacturer estimates, no “up to” claims – just actual costs.
Here is the annual cost comparison that might surprise you:
| Annual Cost | BYD Atto 3 (EV) | Old Hatchback Petrol |
|---|---|---|
| Fuel / Charging | $1,920 ($160/month) | $4,800 ($400/month) |
| Road Tax | $1,500 | $700 |
| Maintenance | $0 (free) | $1,200 ($300/quarter) |
| Tyre Replacement | $480 ($120/tyre x 4) | $100 ($80/tyre x 4) |
| Total Per Year | $3,900 | $6,800 |
Net savings with the BYD Atto 3: $2,900 per year.
That is roughly $242 a month in my pocket. But before you rush to trade in your petrol car, there is one number that catches most people off guard – and it caught me too.
The Counterintuitive Thing About EV Road Tax in Singapore
Most people assume EVs are cheaper across the board. Wrong. In Singapore, electric vehicles attract significantly higher road tax than equivalent petrol cars.
My BYD Atto 3 costs $1,500 a year in road tax. My old hatchback? Just $700 a year. That is an $800 difference – every year.
This is because Singapore road tax for EVs is calculated based on vehicle weight, and the Atto 3 battery adds considerable kerb weight. So while you are saving on fuel and maintenance, you are paying more to the government to drive.
The good news: even with this road tax penalty, the EV still comes out ahead by $2,900 per year. The fuel savings are that dominant.
8 Months of Real Ownership Data
Here is what I actually spent over 8 months:
| Cost (8 Months) | BYD Atto 3 | Old Hatchback Petrol |
|---|---|---|
| Fuel / Charging | ~$1,280 | ~$3,200 |
| Road Tax (8 months) | ~$1,000 | ~$467 |
| Maintenance | $0 | ~$800 |
| Tyre (8 months) | ~$320 | ~$67 |
| Total 8 Months | ~$2,647 | ~$4,534 |
After 8 months, the Atto 3 has saved me approximately $1,887 in direct operating costs compared to if I had kept driving the petrol hatchback.
Fuel vs Charging: Where the EV Wins Big
Here is the breakdown of why EVs make financial sense for Singapore drivers who clock reasonable mileage:
- Driving about 15,000-18,000km a year in Singapore
- I charge at public Charge+ stations at $0.629/kWh
- My petrol hatchback was spending roughly $400/month on RON 95 fuel
- The Atto 3 costs about $160/month to charge at the same distance
That is a $240/month saving on fuel alone. Charge+ is widely available across Singapore and I have had no issues with accessibility. If you are relying purely on public charging like me (no home charger needed), the math still works.
Range and Road Trips: The Honest Truth
The BYD Atto 3 has a real-world range of about 350km per full charge. For daily Singapore driving, this is more than enough – I typically charge once a week or less.
For road trips to Malaysia, the situation is different. Genting Highlands, for example, requires a significant climb and eats into your battery faster than flat driving. Expect to need more charging stops and longer rest stops along the way. It is less convenient than a petrol car on a long road trip.
But here is the reality check: most Singapore drivers do maybe 2 Genting trips a year. That is 50 weeks out of 52 you are driving locally. The road trip inconvenience is a few weekends per year, not an everyday problem.
For the other 50 weeks, you are enjoying lower fuel costs and zero maintenance headaches in Singapore. The math still favours the EV for the majority of your driving.
Maintenance: The Hidden EV Advantage
My BYD Atto 3 came with complimentary scheduled maintenance for the first few years. This is not unique to BYD – most EV brands offer this. Why? Because EVs have far fewer moving parts:
- No oil changes
- No timing belt replacements
- No transmission service
- Regenerative braking reduces brake wear
My old petrol hatchback was costing $300 every quarter in maintenance – timing belt services, oil changes, transmission fluid, the works. At $1,200 a year, that is a significant cost that disappears with an EV.
Tyre Costs: The EV Reality Check
Here is one area where EVs actually cost more – and it is not small. The Atto 3 uses 18-inch tyres and they are not cheap:
- Atto 3 (18-inch): $120 per tyre x 4 = $480 every 2 years = $240/year
- Old hatchback (16-inch): $80 per tyre x 4 = $320 every 3 years = ~$107/year
EV tyres wear faster because of instant torque and the heavier weight of the car. Budget an extra $130-150/year for tyres compared to a smaller petrol car. This is a real cost people do not talk about enough.
Is It Worth Switching to an EV in Singapore in 2026?
Based on 8 months of real data, yes – if you are driving a similar distance. Here is my honest assessment:
| Factor | EV Verdict |
|---|---|
| Fuel savings | HUGE win – $240/mo saved |
| Road tax | Loss – pays $800 more per year |
| Maintenance | WIN if free, neutral if paid |
| Tyres | Loss – ~$130 more per year |
| Overall annual net | +$2,900 in my case |
The ROI depends heavily on:
- How much you drive (more km = bigger EV savings)
- Whether you have a home charger (saves time more than money)
- Your current petrol car fuel efficiency
- Whether your EV includes free maintenance
How Long to Break Even?
If you are switching from a petrol car to an EV, the biggest costs are:
- COE premium difference (if applicable)
- Purchase price difference
- Installation of home charger (if you want one)
Operating cost savings of $2,900/year are substantial, but the upfront cost difference needs to be weighed against how long you plan to keep the car. Run your own numbers based on your specific situation.
Frequently Asked Questions
Is road tax for EVs really higher than petrol cars in Singapore?
Yes. Singapore road tax for EVs is calculated based on vehicle weight, and with the heavy battery packs in EVs like the BYD Atto 3, this results in higher annual road tax compared to an equivalent petrol car. The Atto 3 costs $1,500/year in road tax versus a typical hatchback at $700/year.
How much does it cost to charge a BYD Atto 3 in Singapore?
At public Charge+ stations (my primary charger), the cost is $0.629/kWh. Based on my usage pattern of 15,000-18,000km/year, I spend approximately $160/month on charging. At home with a wallbox charger (off-peak rates), it would be significantly cheaper.
Do I need a home charger for the BYD Atto 3?
No. I use only public charging (Charge+ network) and have not had issues. However, having a home charger is more convenient and can be cheaper if you are on an off-peak electricity plan. I manage fine without one.
How much can I save switching from petrol to EV in Singapore?
Based on my 8-month ownership comparison, I save approximately $2,900 per year in total operating costs (fuel, maintenance, road tax, tyres) switching from a petrol hatchback to a BYD Atto 3. The biggest savings come from fuel – $240/month compared to my old car $400/month.
What is the real-world range of the BYD Atto 3?
Real-world range is about 350km per full charge in Singapore conditions. For daily local driving, this is more than sufficient – I charge roughly once a week. For road trips to Malaysia, expect shorter range between charges and longer travel time due to the terrain and need for charging stops.
Are EV tyres more expensive than petrol car tyres?
Yes. EV tyres (like the 18-inch tyres on the Atto 3) cost more and wear faster due to the car weight and instant torque. I budget $480 for a full set every 2 years, versus $320 for my old 16-inch hatchback tyres that lasted 3 years. Budget an extra ~$130/year for EV tyres.
Bottom Line
8 months in, the BYD Atto 3 has saved me about $1,887 in direct operating costs compared to my petrol hatchback. Even accounting for the higher road tax – which surprises most people – the EV comes out $2,900/year ahead.
The fuel savings alone are worth it if you drive 20,000km+ a year. The maintenance-free aspect is a bonus. Just do not expect EVs to be cheaper on road tax – in Singapore, they are not.
Road trips to Malaysia are less convenient in an EV. But if you are like most Singapore drivers doing 2 Genting trips a year max, 50 weeks of local driving still favour the EV financially. The everyday savings outweigh the occasional road trip inconvenience.
