Hybrid Car vs Petrol: Which is Best?
Understand the key differences between hybrid and petrol cars, and discover which option best suits your lifestyle.
What is a Hybrid Car With an Electric Motor?
Hybrid cars combine a petrol or diesel engine with electric power to help reduce fuel consumption and lower emissions. Depending on the type of hybrid, the electric motor may assist the engine or drive the car for short periods. SEAT currently offers two types of hybrid technology: Mild Hybrid (MHEV) and Plug-in Hybrid (PHEV).
How Hybrid Cars Work
Hybrid cars ingeniously combine a traditional petrol internal combustion engine with an electric motor and a battery pack. In MHEVs, the petrol engine provides the primary propulsion power, while the electric motor assists during acceleration and recovers energy from braking. The electric motor does not independently propel the vehicle in MHEVs.
In PHEVs, the car can be powered by the electric motor, the petrol engine, or both, depending on the driving conditions and the state of charge. The battery pack stores energy captured from regenerative braking, which can then be used to power the electric motor. This system allows hybrids to shut off the petrol engine when idling and use the electric motor, thereby saving fuel. Sophisticated transmission systems ensure a smooth transition between the petrol engine and electric motor.
Types of Hybrid Vehicles Available From SEAT
Mild Hybrid (MHEV)
Mild hybrid vehicles use a small electric motor to support the engine, particularly during acceleration and stop-start driving.
They don’t need to be plugged in – the battery recharges automatically while driving.
This system improves efficiency and helps reduce CO₂ emissions.
Available on models like the SEAT Leon and SEAT Leon ST.
Plug-in Hybrid (PHEV)
Plug-in hybrids offer the best of both worlds: electric-only driving for shorter and medium distances and a petrol engine for longer journeys. A plug in hybrid car can operate primarily on electric power for short and medium trips, leading to reduced fuel consumption.
You can charge the battery at home or at public charging points.
They offer lower fuel consumption and reduced emissions. Plug in hybrid cars are becoming increasingly popular due to their zero-emissions driving and increased electric-only range compared to standard hybrids.
SEAT Leon e-HYBRID and SEAT Leon ST e-HYBRID are great examples of PHEVs in the range.
SEAT’s plug-in hybrid models offer significant electric range and capacity while retaining the convenience of a petrol engine.
Since PHEV brings better driving performance and a bigger saving potential, SEAT does not currently offer full hybrid (HEV) vehicles. Also, you can use your PHEV in full electric mode. All hybrid models are either mild or plug-in hybrid.

What is a Petrol Car?
Petrol cars rely entirely on a combustion engine. They are typically simpler, more affordable, and widely available. SEAT offers a broad range of efficient and dynamic petrol vehicles, including the SEAT Ibiza, Leon, Arona and Ateca.
Petrol and diesel cars are often compared in terms of fuel types, hybrid technologies and future regulations affecting new car sales.
How Petrol Cars Work
Petrol cars run on a regular engine that burns petrol (also called gasoline) to create power. The engine works in four steps: pulling in air and fuel, squeezing it, setting it on fire to create power, and pushing out the smoke. This power turns the wheels and gets the car moving. Petrol engines come in different shapes and sizes, and many people enjoy the smooth, familiar feel they offer when driving.
Why Choose a Petrol Car?
What’s good:
Cheaper to buy – Petrol cars usually cost less than hybrids.
Fast to refuel – Just stop at a petrol station and you’re ready to go.
Simple tech – Easy to look after, and most mechanics know how to fix them.
Things to think about:
Fuel prices – Petrol prices rise annually and faster than electricity costs. With your own solar panels, electricity expenses can drop to 0.
More pollution – Petrol engines release more CO₂ than hybrids.
Value drops faster – They may lose value quicker than hybrids or electric cars.
