Plug-in Hybrid (PHEV)
Plug-in Hybrids combine a petrol engine with a larger battery that can be charged externally. They allow short trips to be driven purely on electric power, while the petrol engine provides backup for longer journeys. Best suited for buyers who want flexibility and have access to charging facilities.
Recommended Fuel – Regular E20 petrol + external charging
Benefits
- Can run purely on electric for short distances
- Flexible for both city and highway use
- Lower emissions compared to pure petrol or diesel
Not Suitable for
