How BEVs and PHEVs compare
| Question | BEV | PHEV |
|---|---|---|
| Daily energy | Electricity only | Electricity first, petrol when needed |
| Charging habit | Essential | Essential to realise the intended benefit |
| Long trips | Charging stops may be needed | Can refuel with petrol after electric range is used |
| Charging speed | Usually supports fast DC public charging | Usually AC (slower) charging only |
| Servicing | No engine oil or exhaust to service | Still needs oil changes like a petrol car |
| Mechanical complexity | No combustion engine | Electric and combustion systems |
| Tailpipe emissions | None while driving | Present whenever the engine runs |
Choose a BEV if…
- You have dependable routine charging
- Available models cover your regular long drives and practical needs
- You want to leave petrol, oil changes and tailpipe emissions behind
Consider a PHEV if…
- You can charge most days and most routine trips fit its electric range
- You frequently travel where public charging is genuinely impractical
- The exact vehicle’s space, towing or other capability is not available in a suitable BEV
Check the PHEV’s electric range, fuel use after the battery is depleted, servicing schedule and boot-space compromise. Test your charging routine with our routine guide, and check whether you need a home charger.
Common questions
Do you have to plug in a PHEV?
You do not have to, but you should. A PHEV drives fine on petrol alone, yet its whole advantage comes from charging it — usually from an ordinary power point or home charger overnight — so short trips run on cheaper electricity. Left unplugged, it behaves like a heavier, thirstier petrol car. See whether you need a home charger.
Does a PHEV charge itself?
It can recover some energy while slowing and the engine may charge the battery, but regular plugging in is what allows meaningful electric driving without burning petrol.
Is a PHEV automatically cheaper to run?
No. It depends on how often you charge, electricity and petrol prices, actual fuel use, servicing, finance and purchase price. For a worked side-by-side comparison, see what an EV really costs to own.
Does the electric-car FBT exemption apply to a PHEV?
Generally no. PHEVs provided through a salary-packaging arrangement from 1 April 2025 are not eligible for the electric-car fringe benefits tax exemption. Some arrangements entered into before that date may continue under transitional rules. Check the ATO's FBT and electric cars guidance or a tax adviser before using a PHEV purchase in a salary-packaging comparison with a BEV.
