Purchase price is only part of the story. When you add charging vs fuel, insurance, maintenance and depreciation, which is actually cheaper over five years? We ran the full numbers.
The headline debate between electric and petrol cars usually focuses on purchase price, and electric usually loses. But purchase price is only one cost among many. Over a typical five-year ownership period, the total cost of ownership — what the car actually costs you to buy, run and eventually sell — tells a very different story.
Here is a complete, honest breakdown of electric vs petrol costs in 2026.
For this analysis, we compare two similarly sized family saloons/crossovers:
This is a fair comparison because they come from the same manufacturer, similar size class, and target similar buyers.
The petrol Tucson is $9,000 cheaper upfront. In the US, the Ioniq 6 may qualify for up to $7,500 in federal tax credits, narrowing the gap to $1,500. In countries without subsidies, the full gap remains.
After US federal credit:** - Ioniq 6 effective price: ~$31,500 - Tucson petrol: ~$30,000 - **Difference: ~$1,500 (petrol cheaper)
Without US tax credit: - Difference: $9,000 (petrol cheaper)
This is where the equation begins to flip. Petrol and electricity costs vary by region, but the direction is consistent.
Assuming annual mileage of 12,000 miles (US average):
Petrol Tucson (30 MPG combined): - 12,000 miles ÷ 30 MPG = 400 gallons - At $3.50/gallon average: $1,400/year
Ioniq 6 (3.5 miles/kWh efficiency): - 12,000 miles ÷ 3.5 = 3,430 kWh - At $0.14/kWh home charging average: $480/year
Annual saving: $920 in fuel costs** **5-year saving: $4,600
Note: Public charging is more expensive than home charging. If you charge primarily at public DC fast chargers, costs rise to roughly $0.25–0.35/kWh, significantly reducing this advantage. Home charging is essential to maximise the fuel cost benefit.
Electric cars have fundamentally fewer moving parts. No oil changes, no gearbox fluid, no spark plugs, no exhaust system, no clutch. The brake pads also last longer due to regenerative braking.
Average annual maintenance cost (US data): - Petrol car: $800–$1,000/year (includes oil changes, filters, tyres, misc) - Electric car: $400–$500/year (primarily tyres and scheduled checks)
5-year saving: approximately $2,500
Major repairs (engine, gearbox) favour EVs further — no equivalent component exists to fail. However, high-voltage battery repair or replacement (rare before 8–10 years) can be expensive if it occurs outside warranty.
EV insurance is typically 10–15% higher than equivalent petrol models. Repair costs for EVs are higher — battery pack proximity to impact zones, specialist repair requirements and parts costs all contribute.
Annual insurance premium (mid-range estimate): - Petrol: $1,400 - EV: $1,600
5-year extra cost for EV: $1,000
This is the most volatile and uncertain cost. EV depreciation has been higher than petrol in recent years due to rapid technology improvements (making older models feel outdated), battery range uncertainty and market fluctuation.
However, the picture is improving. Tesla Model 3 and Hyundai Ioniq 5/6 are now holding value better than early data suggested. The risk of significant depreciation remains higher for less-established EV brands.
Conservative estimate: - Petrol car retains ~50% of value after 5 years - EV retains ~45% of value after 5 years (improving as confidence grows)
On a $39,000 EV vs $30,000 petrol car, this difference is significant in absolute terms: - Petrol residual value: $15,000 - EV residual value: $17,550 (45% of $39k)
Wait — the EV residual is higher in absolute terms despite the lower percentage retention. This calculation works in EVs' favour if the technology remains current.
Many countries offer significant EV incentives: - Reduced or zero annual road tax (UK, Germany, Netherlands) - Congestion charge exemptions (London) - Free parking in many city centres (Norway) - HOV lane access (US states)
These benefits are being phased out as EV adoption grows, but remain real today.
Pulling all figures together for a US buyer with tax credit eligibility:
| Cost | Petrol Tucson | Ioniq 6 EV | |------|--------------|------------| | Purchase (after credits) | $30,000 | $31,500 | | Fuel/electricity (5yr) | $7,000 | $2,400 | | Maintenance (5yr) | $4,500 | $2,250 | | Insurance (5yr) | $7,000 | $8,000 | | Residual value loss | $15,000 | $21,450 | | Total 5-year cost | $33,500 | $25,600 |
EV is approximately $7,900 cheaper over five years for the US buyer with tax credit.
Without the tax credit, the EV advantage narrows to approximately -$600 (petrol marginally cheaper). The tax credit is decisive for US buyers.
Despite the overall EV advantage in total cost, petrol remains the better choice in several situations:
What happens if the EV battery fails?** Modern EV batteries are warranted for 8 years or 100,000+ miles by most manufacturers. Battery failure within that period is covered under warranty. After warranty, replacement costs have fallen significantly — a pack that cost $15,000 in 2019 costs $7,000–9,000 in 2026.
Is it true EVs are bad for the environment due to battery production?** EV manufacturing does produce more CO2 than petrol car manufacturing — primarily from battery production. However, over the car's lifetime, the lower emissions from electricity vs petrol result in lower total lifetime emissions in most electricity grids. As grids become greener, this advantage grows.
Do EV tyres wear out faster?** Yes. EVs are heavier (battery weight) and have instant torque delivery, which stresses tyres more. Expect 20–30% shorter tyre life than equivalent petrol vehicles.
Can I take an EV on a road trip?** Yes, but planning is more important than with petrol. Most EV navigation systems now route automatically through charging stops. The key is knowing approximate charge times: a 30-minute fast-charge stop at a 150kW+ charger adds 100+ miles in most modern EVs.
