Analysis
Both vehicles drove at 130 km/h for the entire trip. The Q8 SUV (combustion) makes 2 stops totalling 10 min, the Model X 90D (electric) 3 stops totalling 51 min. Road safety reminder: on a trip of this duration, it is recommended to stop for at least 51 min total (17 min every 2h). The energy cost is 63,70 € for Model X 90D versus 359,34 € for Q8 SUV.
The official WLTP figures (22,8 kWh/100km for Model X 90D and 11,4 L/100km for Q8 SUV) 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 23,5 kWh/100km (Model X 90D) and 23,3 L/100km (Q8 SUV). Full methodology: see the dedicated button above the summary.
On a 200 km round trip (e.g. a weekend getaway), the electric or plug-in hybrid vehicle completes the entire journey on home energy at 0.18 €/kWh - with no charging stop. The time advantage of the combustion car on long-distance motorways disappears entirely, and the economic advantage of electric strengthens considerably.
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 Q8 SUV 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: 63,70 € (Model X 90D) and 359,34 € (Q8 SUV). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
