Both vehicles drive at 130 km/h. The difference comes from charging stops.
Analysis
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 2 stops totalling 29 min for the Megane E-Tech Electric versus 6 stops totalling 98 min for the MG4 Standard RWD.
The official WLTP figures (15,8 kWh/100km for Megane E-Tech Electric and 17,0 kWh/100km for MG4 Standard RWD) are measured on a mixed cycle averaging ~46 km/h. At a steady 130 km/h, aerodynamic drag weighs much more heavily — it grows with the square of speed. Caralogy calculates a motorway consumption specific to each vehicle based on its aerodynamic profile (SCx), weight and power curve — not a uniform correction factor. For this trip, the simulation yields 13,8 kWh/100km (Megane E-Tech Electric) and 20,4 kWh/100km (MG4 Standard RWD). Full methodology: see the dedicated button above the summary.
During the 29 minutes of charging for the Megane E-Tech Electric, range recovers by 414 km. During the 98 cumulative minutes for the MG4 Standard RWD, range recovers by 581 km. Per minute: the Megane E-Tech Electric recovers 2,4× faster. At this rate, the charging stop blends into the trip rhythm — just enough time for a coffee. At a lower rate, it dictates the pace.
A Peugeot 308 1.2 PureTech 130 (equivalent segment) consumes about 6,8 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~97 €. That is 2,8× the electric cost of the Megane E-Tech Electric and 1,6× that of the MG4 Standard RWD. The gap narrows in winter but never reverses.
The cost per kilometre depends on the electricity rate applied to each segment — based on the energy source used at that point of the trip.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the Megane E-Tech Electric arrives in 7h30 with 2 charging stops.
WLTP consumption does not reflect motorway reality. Aerodynamic drag grows with the square of speed, so real consumption is 15 to 25 % higher than WLTP combined. Caralogy calculates a highway consumption specific to each vehicle based on its aerodynamic profile (SCx), weight and power curve.
Total time = driving time + charging time. Driving time is calculated at an average speed of 130 km/h on the motorway (adjustable). Charging time is calculated based on the real power curve of each vehicle, respecting the optimal 10 → 80 % range and the maximum power accepted by the chargers on the route.
No. The displayed cost covers only the energy consumed during the trip: kWh × energy rate, with a mix of home charging and DC fast chargers. Battery wear is a long-term ownership cost, not a trip cost.
Electric: 35,17 € (Megane E-Tech Electric) and 60,17 € (MG4 Standard RWD). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
