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 E 400 e 4MATIC W214 versus 2 stops totalling 10 min for the 740Le xDrive iPerformance G11.
The official WLTP figures (23,0 kWh/100km for E 400 e 4MATIC W214 and 22,6 kWh/100km for 740Le xDrive iPerformance G11) 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 9,4 L/100km (E 400 e 4MATIC W214) and 12,5 L/100km (740Le xDrive iPerformance G11). Full methodology: see the assumptions below the controls.
A BMW 530i (equivalent segment) consumes about 8,0 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~115 €. That is 0,8× the electric cost of the E 400 e 4MATIC W214 and 0,6× that of the 740Le xDrive iPerformance G11. The gap narrows in winter but never reverses.

On Paris → Marseille (775 km at 130 km/h), the E 400 e 4MATIC W214 arrives in 7h06 with 1 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.
On this trip, the energy used costs 144.46 € (E 400 e 4MATIC W214) and 200.96 € (740Le xDrive iPerformance G11). For reference, an equivalent BMW 530i (~8.0 L/100 km) would cost about 115 € in fuel.
