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 10 min for the 740Le xDrive iPerformance G11 versus 5 stops totalling 79 min for the Dolphin Active 70kW.
The official WLTP figures (22,6 kWh/100km for 740Le xDrive iPerformance G11 and 13,8 kWh/100km for Dolphin Active 70kW) 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 12,5 L/100km (740Le xDrive iPerformance G11) and 14,9 kWh/100km (Dolphin Active 70kW). Full methodology: see the dedicated button above the summary.
A Mercedes S 450 (equivalent segment) consumes about 9,0 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~129 €. That is 0,7× the electric cost of the 740Le xDrive iPerformance G11 and 2,4× that of the Dolphin Active 70kW. 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 740Le xDrive iPerformance G11 arrives in 7h11 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: 188,39 € (740Le xDrive iPerformance G11) and 53,74 € (Dolphin Active 70kW). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
