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 20 min for the Model X Performance versus 4 stops totalling 65 min for the Mustang Mach-E RWD.
The official WLTP figures (23,6 kWh/100km for Model X Performance and 17,0 kWh/100km for Mustang Mach-E 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 21,1 kWh/100km (Model X Performance) and 21,3 kWh/100km (Mustang Mach-E RWD). Full methodology: see the dedicated button above the summary.
During the 20 minutes of charging for the Model X Performance, range recovers by 380 km. During the 65 cumulative minutes for the Mustang Mach-E RWD, range recovers by 507 km. Per minute: the Model X Performance 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 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 2,1× the electric cost of the Model X Performance and 1,9× that of the Mustang Mach-E 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 Model X Performance arrives in 7h21 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: 52,16 € (Model X Performance) and 58,99 € (Mustang Mach-E 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.
