Analysis
Both vehicles drove at 130 km/h for the entire trip. The X4 M40d G02 (combustion) makes no stop, the XM 50e G09 (plug-in hybrid) 1 stop of 5 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 139,06 € for XM 50e G09 versus 99,26 € for X4 M40d G02.
The official WLTP figures (32,2 kWh/100km for XM 50e G09 and 6,6 L/100km for X4 M40d G02) 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 9,5 L/100km (XM 50e G09) and 6,3 L/100km (X4 M40d G02). 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.

On Paris → Marseille (775 km at 130 km/h), the X4 M40d G02 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: 139,06 € (XM 50e G09) and 99,26 € (X4 M40d G02). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
