Pure EV vs hybrid vs plug-in hybrid
The difference that matters most is whether you plug the car in and how far it can go on electricity alone. Dealers use the word "hybrid" for several different things, so it pays to know which one you are being offered.
The short answer
- Pure EV (BEV): battery and electric motor only. You charge it from the mains or a public charger.
- Plug-in hybrid (PHEV): a larger battery you plug in, plus a petrol engine. Officially about 30 to 90 miles on electricity alone.
- Full hybrid (HEV, "self-charging"): a petrol engine with a small battery charged by the engine and braking. No plug.
- Mild hybrid: a small motor assists the petrol engine but cannot drive the car on electricity alone. It is not a substitute for any of the above.
Side by side
| Pure EV | Plug-in hybrid | Full hybrid | |
|---|---|---|---|
| Plug in? | Yes | Yes, to get the benefit | No |
| Electric-only range | Roughly 100 to 400 miles real-world | Officially about 30 to 90 miles | Very short, low speed |
| Running costs | Lowest per mile if you charge at home | Very low if you charge often | Better than petrol |
| Company car tax | Very low: 4% in 2026/27 | Depends on emissions and electric range | Based on emissions |
| Watch out for | Charging access and winter range | Never plugging in | Little benefit on motorways |
Which type suits you?
- You can charge where you park: a pure EV usually gives the lowest running costs. A plug-in hybrid works if you also make regular long trips without planning.
- You cannot charge at home or work: a full hybrid is normally the better choice. A plug-in hybrid is expensive to carry around if you never plug it in.
- You want the simplest change from petrol: a full hybrid needs no change to your routine.

Frequently asked questions
What is the difference between a pure EV, a hybrid and a plug-in hybrid?
A pure EV (battery electric vehicle) has no petrol or diesel engine and is charged from the mains or a public charger. A full hybrid, often called self-charging, has a petrol engine and a small battery that is topped up by the engine and braking; you never plug it in. A plug-in hybrid (PHEV) has a larger battery you charge from a socket, giving an official electric-only range that is typically 30 to 90 miles, plus a petrol engine for longer trips.
Is a plug-in hybrid worth it if I cannot charge at home?
Usually not. A plug-in hybrid only delivers its low running costs if you plug it in regularly. Once the battery is flat you are carrying the weight of a larger battery, and many are less efficient than a full hybrid in that state. If you cannot charge at home or at work, a full hybrid is normally the better choice.
What is a mild hybrid, and is it worth paying extra for?
A mild hybrid uses a small electric motor to assist the petrol engine and recover braking energy, but it cannot drive the car on electricity alone. It can improve economy slightly, but it is not a substitute for a full hybrid, a plug-in hybrid or an EV. Be EV Wise covers full hybrids, plug-in hybrids and pure EVs.
