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 911 Carrera 4S 991.1 versus 1 stop of 5 min for the Boxster PDK 987.
The official WLTP figures (11,2 L/100km for 911 Carrera 4S 991.1 and 10,1 L/100km for Boxster PDK 987) 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 9,0 L/100km (911 Carrera 4S 991.1) and 10,6 L/100km (Boxster PDK 987). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 911 Carrera 4S 991.1 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.
Electric: 141,80 € (911 Carrera 4S 991.1) and 167,42 € (Boxster PDK 987). An equivalent BMW M340i (~9,5 L/100 km) would cost about 136 € in motorway fuel. Electric costs less in energy but adds charging stops.
