The 15-minute lead of the 911 Turbo S 992 does not come from driving speed, but from 3 fewer charging stops on this route (1 vs 4).

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 Turbo S 992 versus 4 stops totalling 20 min for the 718 Boxster.

Motorway consumption: the Caralogy methodology

The official WLTP figures (11,8 L/100km for 911 Turbo S 992 and 9,8 L/100km for 718 Boxster) 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 12,4 L/100km (911 Turbo S 992) and 28,0 L/100km (718 Boxster). 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 911 Turbo S 992 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 208.37 € (911 Turbo S 992) and 470.89 € (718 Boxster). For reference, an equivalent BMW M340i (~9.5 L/100 km) would cost about 136 € in fuel.
