Hybrid vs Mild Hybrid vs Plug-in Hybrid | Simon Shield Cars
Learn the difference between hybrid, mild hybrid and plug-in hybrid cars. A clear guide from Simon Shield Cars, Ipswich, Suffolk, with real examples from our current stock.
Electrified cars are more popular than ever, but the terminology can be confusing. After a recent Tiktok comment highlighted the difference between a PHEV and a MHEV, we realised it's the perfect time to break things down clearly.
Whether you're considering a hybrid, mild hybrid or plug-in hybrid, understanding how each system works will help you choose the right car for your lifestyle. And with two electrificed models currently in stock - the SEAT Leon e-hybrid and the Ford Focus 1.0 Ecoboost Mhev - we can help to compare them in person too.
What is a plug-in hybrid (PHEV)?
A plug-in hybrid electric vehicle combines a petrol engine with a larger battery that you charge via a plug - at home, at work, or at public charging points.
How it works?
- You can drive short distances on electric power
- Once the battery is empty, the petrol engine takes over
- Best fuel economy when the car is charged regularly
Who it suits:
- Drivers who can charge at home (much cheaper)
- Short commutes, school runs and town driving
- Anyone wanting to reduce fuel costs and emissions
SEAT Leon e-hybrid - a smooth, efficient PHEV with excellent real-world economy.
What is a mild hybrid (MHEV)?
A mild hybrid electric vehicle used a small battery and electric motor to support the petrol engine - but it can't drive on electric alone.
How it works:
- No plugging in
- The battery assists with acceleration and stop-start
- Improves efficiency and smoothness
Who it suits:
- Drivers who want better fuel economy without changing their routine
- Anyone who doesn't have access to home charging
- Those who prefer a tradtional petrol driving feel
Example in stock
Ford Focus 1.0 Ecoboost MHEV- responsive, economical, and ideal for everyday use.
What is a full Hybrid (HEV)?
A hybrid electric vehicle sits between the two systems above. It doesn't plug in, but it can drive short distances on electric power.
How it works:
- Charges itself through braking and the engine
- Switches automatically between petrol and electric (how you drive)
- Very efficient in stop-start traffic
Who it suits:
- Town drivers
- Anyone wanting low running costs without charging
- Drivers who want a smooth, quiet drive at low speeds
What the Which? survey says about Hybrid popularity
A recent Which? survey found that full hybrids (HEV) are currently the UK's favourite type of electrified car, scoring highly for reliablity, ease of use and real-world efficiency. Drivers appreciate that hybrids don't need plugging in, yet still deliver excellent fuel economy - especially around town.
This growing confidence in full hybrids explains why so many people are now exploring electrified options for the first time. And it's also why understanding the differences between HEV, MHEV and PHEV systems is more important than ever when choosing your next car.
If you're unsure, we're always happy to talk through your routine and help you choose the right type.
