Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 3 stops totalling 15 min for the 718 Boxster GTS versus 5 stops totalling 25 min for the 911 Targa 4 991.1.
The official WLTP figures (11,2 L/100km for 718 Boxster GTS and 10,5 L/100km for 911 Targa 4 991.1) 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 25,0 L/100km (718 Boxster GTS) and 11,0 L/100km (911 Targa 4 991.1). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 718 Boxster GTS arrives in 7h16 with 3 fuel 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.
On this trip, the energy used costs 420.44 € (718 Boxster GTS) and 185.41 € (911 Targa 4 991.1). For reference, an equivalent BMW M340i (~9.5 L/100 km) would cost about 136 € in fuel.
