PETROL VS DIESEL VS ELECTRIC CAR: WHICH IS REALLY CHEAPER?

EV Channels Review

This "What Car?" video pits a Peugeot 5008 diesel against its petrol counterpart and a Tesla Model Y in a real-world cost comparison across motorway and urban driving. The diesel 5008 demonstrated superior fuel economy on the motorway (59.7 MPG vs. 43.2 MPG for petrol) and in town (25 MPG vs. 19.2 MPG), resulting in lower fuel costs for the diesel despite its higher per-litre price. However, the initial purchase price of the diesel is higher, meaning a high-mileage driver would need approximately five years to recoup the extra cost through fuel savings. Residual values also favor the petrol model. Environmentally, while diesels emit less CO2, they produce more harmful NOx and particulate emissions. The Tesla Model Y proved significantly cheaper to run, especially when charging at home, and also avoided London's congestion and ULEZ charges, making it the most economical and environmentally friendly option overall. The verdict suggests diesel can still be attractive for very high-mileage drivers prioritizing fuel costs over initial outlay and exhaust pipe emissions, but for those concerned about pollution or seeking the lowest running costs, electric is the clear winner.
