Both vehicles drove at 130 km/h for the entire trip. The 911 Turbo 991.2 (combustion) makes 1 stop of 5 min, the Cyberster AWD (electric) 2 stops totalling 45 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 164,81 € for 911 Turbo 991.2 versus 54,76 € for Cyberster AWD.
The official WLTP figures (11,2 L/100km for 911 Turbo 991.2 and 16,7 kWh/100km for Cyberster AWD) 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 9,8 L/100km (911 Turbo 991.2) and 17,5 kWh/100km (Cyberster AWD). Full methodology: see the assumptions below the controls.
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 0.20 €/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 advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the 911 Turbo 991.2 arrives in 7h06 with 1 fuel 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.
On this trip, the energy used costs 164.81 € (911 Turbo 991.2) and 54.76 € (Cyberster AWD). For reference, an equivalent BMW M340i (~9.5 L/100 km) would cost about 136 € in fuel.
