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: 1 stop of 5 min for the 520e G30 versus 4 stops totalling 67 min for the MG4 Long Range RWD.
The official WLTP figures (16,0 kWh/100km for MG4 Long Range RWD and 21,5 kWh/100km for 520e G30) 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 19,2 kWh/100km (MG4 Long Range RWD) and 10,0 L/100km (520e G30). Full methodology: see the dedicated button above the summary.
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 1,8× the electric cost of the MG4 Long Range RWD and 0,7× that of the 520e G30. 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 520e G30 arrives in 7h06 with 1 charging stop.
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: 53,57 € (MG4 Long Range RWD) and 145,64 € (520e G30). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
