The cheapest cars to run in Australia are electric. A BYD Atto 1 costs about $650 a year to charge for 15,000 km on a standard tariff, and roughly $350 if you charge off-peak. Among petrol and hybrid cars, the Toyota Yaris Hybrid is cheapest to fuel at about $1,020 a year, while the Kia Picanto is the cheapest small petrol car to buy, fuel and service combined.
But fuel is only about a third of what a car costs to keep on the road. Servicing, insurance, registration, tyres and depreciation all decide the real number and once you add them up, the ranking shifts in ways the fuel figures alone don't predict.
This guide runs the numbers on 18 models using current Australian fuel and electricity prices, then totals everything into a genuine cost-of-ownership comparison.
Quick answer: cheapest cars to run in 2026
Category | Best pick | Annual energy cost |
|---|---|---|
Cheapest overall | BYD Atto 1 (EV) | $350 – $650 |
Cheapest hybrid | Toyota Yaris Hybrid | about $1,020 |
Cheapest small petrol | Mazda 2 | about $1,545 |
Cheapest petrol SUV | Kia Stonic | about $1,545 |
Cheapest to service | Toyota | about $250 per visit |
Based on 15,000 km a year, petrol at $2.06/L (national average, August 2026) and electricity at 33.5c/kWh standard or 18c/kWh off-peak.
How we calculated these running costs
Every figure below uses the same assumptions, so the comparison is like-for-like:
Distance: 15,000 km per year the Australian average
Petrol: $2.06 per litre. This is the national average ULP price as of August 2026, up 29.4 cents in a month. Victoria is cheapest at about $2.05; the Northern Territory is dearest at about $2.48
Electricity: 33.5c per kWh on a standard tariff, 18c off-peak. NSW averages closer to 28.5c; South Australia runs 34–40c
Fuel economy: manufacturer combined ADR figures. Real-world use typically runs 10–20% higher, especially in city traffic
Servicing: manufacturer capped-price plans, averaged per year
Your costs will vary with where you live and how you drive. The ranking between cars stays broadly the same.
A note on fuel prices: petrol moved nearly 30 cents a litre in a single month in 2026. At 15,000 km in a car using 7L/100km, that swing alone is $315 a year. Treat every fuel figure here as a snapshot, not a fixed cost.
What makes a car cheap to run?
Five things, in roughly this order of impact:
Fuel or energy use the largest variable cost, and where EVs and hybrids win decisively
Depreciation usually the biggest cost of all on a new car, and the one buyers ignore most
Insurance varies by model, driver age, state and safety rating
Servicing a $1,000+ spread over five years between the cheapest and dearest brands
Tyres and consumables small wheels in common sizes are far cheaper to replace
Note that depreciation sits second. A car that's cheap at the pump but loses half its value in three years is not a cheap car. We'll come back to this.
Cheapest petrol and hybrid cars to run in 2026
Hybrids dominate the top of this table. All figures are annual, at 15,000 km and $2.06/L.
Model | L/100km | Fuel cost/year | Servicing/year | Fuel + servicing |
|---|---|---|---|---|
3.3 | $1,020 | $250 | $1,270 | |
3.8 | $1,174 | $300 | $1,474 | |
4.0 | $1,236 | $250 | $1,486 | |
4.2 | $1,298 | $350 | $1,648 | |
4.3 | $1,329 | $300 | $1,629 | |
4.4 | $1,360 | $250 | $1,610 | |
4.7 | $1,452 | $250 | $1,702 | |
5.0 | $1,545 | $365 | $1,910 | |
5.0 | $1,545 | $375 | $1,920 | |
5.2 | $1,607 | $250 | $1,857 | |
6.3 | $1,947 | $365 | $2,312 | |
6.6 | $2,039 | $300 | $2,339 | |
6.7 | $2,070 | $300 | $2,370 | |
7.0 | $2,163 | $350 | $2,513 | |
8.1 | $2,503 | $350 | $2,853 |
Two things stand out.
The Toyota Yaris Hybrid is in a class of its own among combustion cars at 3.3L/100km. It costs less than half what the Haval Jolion costs to fuel a $1,483 annual gap, or $7,415 over five years.
The cheapest car to buy is not the cheapest to run. The MG 3 petrol is Australia's cheapest new car at $20,990 drive-away, but at 6.6L/100km it costs $1,019 a year more to fuel than a Yaris Hybrid. Over seven years that's $7,133 — considerably more than the purchase price gap. See our top 15 cheapest new cars guide for the drive-away figures.
Cheapest electric cars to run in 2026
EVs operate in a different cost universe. Same 15,000 km, at 33.5c/kWh standard and 18c off-peak.
Model | kWh/100km | Standard tariff | Off-peak | With solar | Range |
|---|---|---|---|---|---|
BYD Atto 1 | 13.0 | $653 | $351 | ~$156 | 220 km |
14.1 | $709 | $381 | ~$169 | 340 km | |
15.5 | $779 | $419 | ~$186 | 350 km | |
Tesla Model Y | 15.7 | $789 | $424 | ~$188 | 466 km |
16.0 | $804 | $432 | ~$192 | 310 km | |
17.5 | $879 | $473 | ~$210 | 482 km |
At 15,000 km a year the BYD Atto 1 costs roughly 4.4 cents per kilometre to charge on a standard tariff, dropping to 2.3 cents off-peak.
Compare that to a mid-size petrol SUV at 8L/100km and $2.06/L: 16.5 cents per kilometre, or $2,472 a year. The EV saves $1,819 a year on a standard tariff and $2,121 off-peak.
Notice something in that table, though. Even the largest EV here the Sealion 7, a mid-size SUV costs less to charge than the smallest petrol hatch costs to fuel. Vehicle size barely matters once you're on electrons.
The catch is the purchase price. The cheapest EV in Australia costs roughly $5,500 more than the cheapest petrol car. At $1,800 a year in savings, that's paid back in about three years but only if you can charge at home. Relying on public DC fast charging at 60–80c/kWh roughly triples the running cost and erases most of the advantage.
The full picture: total annual running costs
This is what the fuel tables miss. Below is every major running cost for five representative cars, at 15,000 km a year.
Yaris Hybrid | Picanto | MG ZS petrol | Haval Jolion | BYD Dolphin (EV) | |
|---|---|---|---|---|---|
Fuel / charging | $1,020 | $1,607 | $2,070 | $2,503 | $709 |
Servicing | $250 | $250 | $300 | $350 | $200 |
Insurance (est.) | $1,350 | $1,250 | $1,400 | $1,500 | $1,650 |
Registration + CTP | $900 | $850 | $900 | $950 | $800 |
Tyres (amortised) | $240 | $220 | $250 | $280 | $300 |
Total per year | $3,760 | $4,177 | $4,920 | $5,583 | $3,659 |
Over 5 years | $18,800 | $20,885 | $24,600 | $27,915 | $18,295 |
Insurance and registration are estimates for a 35-year-old driver with a clean record in a metropolitan area. Both vary substantially check car insurance costs by state for your situation. Tyres assume a $650 set replaced every 40,000 km.
Three findings worth pausing on:
The EV wins overall, but only just. The Dolphin's charging advantage is partly eaten by higher insurance (EVs cost more to repair) and pricier tyres (heavier cars, wider rubber). On a standard tariff it beats the Yaris Hybrid by $101 a year. Charge off-peak and the gap widens to $429.
The gap between best and worst is $1,924 a year. Over five years, choosing a Yaris Hybrid over a Haval Jolion saves $9,115 more than a third of the Jolion's purchase price.
Fuel is only 27% of the Yaris Hybrid's running costs but 45% of the Jolion's. The more efficient the car, the more the fixed costs dominate which is why insurance and registration deserve as much shopping around as the car itself.
The cost nobody puts in the table: depreciation
Depreciation is usually the single largest cost of owning a new car, and it dwarfs the differences above.
A new car typically loses 10–15% the moment you drive away, then 5–10% a year after. On a $30,000 car that's $3,000–4,500 in year one alone more than the entire annual running cost of a Yaris Hybrid.
This is where the value equation gets uncomfortable for the cheap Chinese brands. Toyota and Mazda hold value better than almost anything else in the Australian market. The newer entrants have no established resale track record, and early data suggests steeper curves. A $23,990 SUV that's worth $10,000 in four years has cost you $3,500 a year in depreciation potentially wiping out every dollar you saved on the purchase price.
Our guide to the hidden costs of owning a car covers this in detail, and if depreciation is your main concern, it's worth asking whether new is right at all — a two-year-old car has already absorbed the steepest drop. We've run the numbers in is it cheaper to buy new or used, or you can browse used cars directly.
Servicing: the cost you can predict
Unlike fuel, servicing is knowable in advance because most brands publish capped prices.
Brand | Per service | Plan length |
|---|---|---|
Toyota | about $250 | 5 years |
MG | $250 – $350 | up to 7 years |
Suzuki | $250 – $350 | 5 years |
Hyundai | $300 – $400 | Lifetime |
Kia | $300 – $450 | 7 years |
Mazda | $330 – $400 | 5 years |
European luxury | $600 – $1,000+ | Prepaid packs |
Over five years, a Toyota costs about $1,250 to service and a BMW around $4,000 a $2,750 difference that never appears in any purchase-price comparison. Full breakdown in our car service cost guide.
EVs cost less again. No oil, no spark plugs, no fuel filters, no exhaust. Most EVs run $150–300 a year, roughly 30–50% below a comparable petrol car, and regenerative braking makes brake pads last dramatically longer.
Where you live changes everything
Two identical cars can cost hundreds of dollars a year apart purely on postcode.
Fuel ranges from about $2.05/L in Victoria to $2.48/L in the Northern Territory. At 15,000 km in a 7L/100km car, that's a $451 annual difference for the same driving.
Electricity runs 27–32c/kWh in Victoria and the ACT, around 28.5c in NSW, and 34–40c in South Australia meaning an EV's advantage is largest in Victoria and smallest in SA.
Registration and CTP vary widely by state, and some states offer EV concessions that shift the calculation further.
Cheapest cars to run overall: our 2026 picks
1. Toyota Yaris Hybrid the lowest total cost of any petrol-powered car we ran. Best-in-class fuel use, cheapest servicing in Australia, strong resale, cheap to insure. If you can only buy one car and want certainty, this is it.
2. BYD Dolphin cheapest overall if you charge at home, and the gap becomes decisive on an off-peak tariff. Needs a driveway and a wallbox to make sense.
3. Toyota Corolla Hybrid the practical all-rounder. Slightly thirstier than the Yaris, considerably more usable, same servicing and resale advantages.
4. Kia Picanto cheapest to buy of the mainstream brands and cheap to service, with a seven-year warranty. The value pick for low-kilometre city drivers where fuel matters less.
5. Suzuki Swift Hybrid a genuinely cheap hybrid at $25,490 drive-away with 3.8L/100km. The three-star ANCAP rating is the trade-off.
You can compare the Swift Hybrid and Yaris Hybrid side by side, or put the Picanto up against the Swift.
How to cut your running costs
Match the powertrain to your kilometres. Under 10,000 km a year, a cheap petrol car usually wins you'll never recover a hybrid or EV premium. Over 20,000 km, an EV becomes very hard to beat.
Charge off-peak. Shifting an EV to an off-peak tariff cuts the energy bill roughly in half. Solar cuts it by 75%.
Shop insurance annually. Loyalty is expensive; premiums for identical cover routinely vary by hundreds of dollars.
Use an independent mechanic once out of capped-price cover. Typically 20–40% cheaper, and it does not void your warranty under Australian Consumer Law.
Keep tyres inflated. Under-inflation alone can cost 3–5% in fuel economy.
Buy the efficient version. The hybrid premium on a Corolla or RAV4 is usually recovered within three to four years at average kilometres.
Conclusion
In 2026 the cheapest cars to run in Australia are electric, led by the BYD Atto 1 at roughly $350–650 a year to charge. Among combustion cars the Toyota Yaris Hybrid is unmatched, costing about $1,020 a year in fuel and around $3,760 all-in.
But the more useful conclusion is that fuel economy alone is a poor guide. Once servicing, insurance, registration, tyres and depreciation are counted, the spread between the cheapest and dearest small cars on this list is nearly $2,000 a year and the cheapest car to buy sits in the middle of the pack, not at the top.
Work out your annual kilometres first, then choose the powertrain that matches. Browse new cars, compare two models side by side, or read our average new car price guide to see where your budget lands.
