The 5-minute lead of the 718 Boxster GTS does not come from driving speed, but from one fewer charging stop on this route (3 vs 4).

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 4 stops totalling 20 min for the 718 Cayman.

Motorway consumption: the Caralogy methodology

The official WLTP figures (11,2 L/100km for 718 Boxster GTS and 9,8 L/100km for 718 Cayman) 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 28,0 L/100km (718 Cayman). Full methodology: see the assumptions below the controls.

Energy cost breakdown for your trip Paris → Marseille

Frequently asked questions

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 470.89 € (718 Cayman). For reference, an equivalent BMW M340i (~9.5 L/100 km) would cost about 136 € in fuel.
