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 C 300 de 4MATIC T-Modell W206 versus 2 stops totalling 20 min for the Model X Performance.
The official WLTP figures (23,6 kWh/100km for Model X Performance and 22,7 kWh/100km for C 300 de 4MATIC T-Modell W206) 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 21,1 kWh/100km (Model X Performance) and 7,2 L/100km (C 300 de 4MATIC T-Modell W206). Full methodology: see the assumptions below the controls.
A Peugeot 3008 1.2 PureTech 130 (equivalent segment) consumes about 7,8 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~112 €. That is 1,8× the electric cost of the Model X Performance and 1,0× that of the C 300 de 4MATIC T-Modell W206. The gap narrows in winter but never reverses.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the C 300 de 4MATIC T-Modell W206 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 62.36 € (Model X Performance) and 110.78 € (C 300 de 4MATIC T-Modell W206). For reference, an equivalent Peugeot 3008 1.2 PureTech 130 (~7.8 L/100 km) would cost about 112 € in fuel.
