Used EV vs Hybrid vs Petrol Car in Australia: What’s Cheapest to Own in 2026?

Short answer? It depends. Anyone who says “EVs always win” or “petrol is still cheaper” is skipping the maths. Your real cost comes down to the purchase price, how far you drive, what you pay for fuel or electricity, servicing, and whether you can charge at home.

To keep things fair, I’ve compared all three using one example: 15,000 km a year over five years. The energy prices are assumptions as of November 2026, so swap in your own numbers before making a call.

At a Glance

What Does “Cheapest Car to Run in Australia” Really Mean?

We’re counting purchase price, fuel or electricity, routine servicing and repairs, insurance, registration, tyres and depreciation. We’re leaving out finance interest and accessories. Costs shift with your model, state and driving habits, so treat this as a guide, not a quote.

Used Electric Cars in Australia: What to Know

Used electric cars in Australia can be very cheap to run, especially if you charge at home overnight. Public fast charging costs noticeably more, so access matters. If you rent, live in an apartment or park on the street, think hard about where you’ll actually plug in. A car that’s cheap on paper but awkward to charge gets old fast.

Buying second-hand electric cars in Australia? Run through this list:

• Ask for a battery health report, not just a “looks fine” from the seller
• Check how much battery warranty is left
• Make sure the charging port suits the chargers you’ll use
• Go through the service records
• Take a proper test drive, including a stretch at highway speed

Used Hybrid Cars in Australia: What to Know

Used hybrid cars in Australia shine in stop-start city driving, where the electric motor does a lot of the work. On long highway runs, the savings shrink. The upside is no range anxiety: fill up and go, same as always.

Check the service history carefully and ask about the hybrid battery’s condition. Hybrids are usually reliable, but a missing service record is a red flag. A good independent inspection is worth every dollar here.

Used Petrol Cars in Australia: What to Know

Petrol gives you the most choice and often the lowest sticker price. If you’re hunting for the cheapest car in Australia, or the best affordable cars in Australia for a tight budget, a used petrol model is often where the search starts. The catch is the fuel bill, and pump prices swing around by suburb and week.

Don’t trust fuel-economy claims on paper alone. Compare real cars, ask how they’ve been driven, and look closely at mechanical condition and servicing. Even the cheapest small SUV in Australia can cost more over time if it’s thirsty or poorly maintained. A well-kept petrol car can easily beat a neglected hybrid.

The Maths, Step by Step

Here’s the formula:

Annual energy cost = annual km ÷ km per unit of energy × price per unit

Our assumptions (illustrative, so check your electricity bill and a fuel price tracker):

• Used EV: 16 kWh/100 km (6.25 km per kWh). Home charging at 30c/kWh, public fast charging at 60c/kWh.
• Used hybrid: 4.5 L/100 km (about 22.2 km per litre) at $2.00/L.
• Used petrol: 8 L/100 km (12.5 km per litre) at $2.00/L.

So an EV charged at home saves around $8,400 in energy over five years compared with petrol. The hybrid saves about $5,250. But if you rely on public chargers, the EV’s edge over a hybrid nearly disappears.

Here’s how the picture changes:

• Lower mileage: the savings shrink, so purchase price matters more.
• Higher mileage: efficient cars pull further ahead.
• City vs highway: hybrids do best in town, while EVs lose some efficiency at high speed.
• Home vs public charging: this is usually the biggest swing of all.

Remember, energy is only one slice of ownership. A cheaper-to-run car that costs $8,000 more upfront might not come out ahead after five years.

Which One Might Suit You?

• Consider a used EV if you can charge conveniently and the range covers your regular trips.
• Consider a used hybrid if you want fuel savings but need petrol’s flexibility.
• Consider a used petrol car if upfront budget, model choice or long-distance freedom matters most.

Your Used-Car Buying Checklist

• Inspect the car in daylight and take it for a test drive
• Review the service records
• Check the vehicle’s history
• Book an independent inspection
• Confirm all costs before you pay

For EVs and hybrids, add a separate battery health check.
