Analysis
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the X5 M50d F15 versus 4 stops totalling 20 min for the Cayenne S 958.2.
The official WLTP figures (9,9 L/100km for Cayenne S 958.2 and 7,2 L/100km for X5 M50d F15) 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 12,4 L/100km (Cayenne S 958.2) and 6,7 L/100km (X5 M50d F15). Full methodology: see the dedicated button above the summary.
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.

On Paris → Marseille (775 km at 130 km/h), the X5 M50d F15 arrives in 7h01 with 0 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: 190,85 € (Cayenne S 958.2) and 103,33 € (X5 M50d F15). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
