The 10-minute lead of the Boxster Spyder does not come from driving speed, but from 2 fewer charging stops on this route (1 vs 3).

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 Boxster Spyder versus 3 stops totalling 15 min for the Panamera 4S.

Motorway consumption: the Caralogy methodology

The official WLTP figures (10,2 L/100km for Panamera 4S and 10,9 L/100km for Boxster Spyder) 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 8,4 L/100km (Panamera 4S) and 11,4 L/100km (Boxster Spyder). Full methodology: see the assumptions below the controls.

Energy cost breakdown for your trip Paris → Marseille

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.

Frequently asked questions

On Paris → Marseille (775 km at 130 km/h), the Boxster Spyder 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 141.27 € (Panamera 4S) and 192.12 € (Boxster Spyder). For reference, an equivalent Mercedes S 450 (~9.0 L/100 km) would cost about 129 € in fuel.
