What is the difference between the types of hybrid cars?
Thinking about switching to a hybrid car, but not sure which type is right for you?
It’s a question we get asked a lot! Below, we’ve put together some helpful information on each type of hybrid available, how they work, and what makes them different. Understanding these options can help you choose a vehicle that suits your driving habits, budget, and lifestyle.
Hybrid cars combine a traditional petrol or diesel engine with an electric motor to improve fuel efficiency and reduce emissions. However, not all hybrids work in the same way. Some provide simple electric assistance to improve efficiency, while others can run on electric power alone for short journeys or even longer distances.
In this guide, we’ll explain the main types of hybrid vehicles, including mild hybrids, full hybrids, and plug-in hybrids, along with their key features, benefits, and limitations. Whether you mainly drive in the city, commute long distances, or want to lower your fuel costs and environmental impact, there’s likely a hybrid option that fits your needs.
Read on to explore the different types of hybrid cars and find out which one could be the best match for you.
A mild hybrid (MHEV) uses a small electric motor to support a petrol or diesel engine, improving fuel efficiency and reducing emissions. The electric system helps with acceleration, stop-start driving, and recovering energy from braking, but it cannot power the car on its own. It charges automatically while driving, so there’s no need to plug it in.
A full hybrid (HEV) can run on electric power, a petrol engine, or a combination of both to drive the car. It automatically switches between power sources to improve fuel efficiency and can travel short distances using electric power alone, especially at low speeds. The battery charges itself while driving through the engine and regenerative braking, so there’s no need to plug it in.
A plug-in hybrid (PHEV) combines a petrol engine with a larger electric battery that can be charged using a home charger or public charging point. It can drive longer distances on electric power alone, helping reduce fuel use and emissions for shorter journeys. When the battery runs low, the petrol engine takes over, giving flexibility for longer trips.
It even factors in terrain and weather to estimate energy usage, ensuring you arrive with plenty of charge and without the stress of range anxiety.
Here’s a simple comparison showing how mild hybrids, full hybrids, plug-in hybrids, and electric cars differ:
| Feature | Mild Hybrid (MHEV) | Full Hybrid (HEV) | Plug-in Hybrid (PHEV) | Electric Vehicle (EV) |
|---|---|---|---|---|
| Electric-only driving | ❌ No | ✅ Yes (short distances) | ✅ Yes (longer distances) | ✅ Yes (always) |
| Engine type | Petrol/diesel + small electric assist | Petrol + electric motor | Petrol + larger electric motor | Electric motor only |
| Battery size | Small | Medium | Large | Very large |
| Needs plugging in? | ❌ No | ❌ No | ✅ Yes | ✅ Yes |
| Charging method | Charges while driving | Charges while driving | Plug-in + driving | Plug-in only |
| Fuel use | Uses fuel all the time | Uses fuel + electricity | Can run on electric or fuel | No fuel used |
| Fuel savings | ⭐ Small improvement | ⭐⭐ Moderate improvement | ⭐⭐⭐ Large savings possible | ⭐⭐⭐⭐ No fuel needed |
| Purchase cost | Lowest | Medium | Higher | Usually highest |
| Driving experience | Like a normal car with extra efficiency | Can switch between engine and electric | Short electric trips are possible | Fully electric driving |
