Both vehicles drive at 130 km/h. The difference comes from charging stops.
Analysis
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 4 stops totalling 30 min for the Taycan GTS J1.1 versus 4 stops totalling 61 min for the Model S P85D.
The official WLTP figures (22,5 kWh/100km for Model S P85D and 20,3 kWh/100km for Taycan GTS J1.1) 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 23,0 kWh/100km (Model S P85D) and 25,5 kWh/100km (Taycan GTS J1.1). Full methodology: see the dedicated button above the summary.
During the 30 minutes of charging for the Taycan GTS J1.1, range recovers by 511 km. During the 61 cumulative minutes for the Model S P85D, range recovers by 502 km. Per minute: the Taycan GTS J1.1 recovers 2,1× faster. At this rate, the charging stop blends into the trip rhythm - just enough time for a coffee. At a lower rate, it dictates the pace.
A BMW 530i (equivalent segment) consumes about 8,0 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~115 €. That is 1,8× the electric cost of the Model S P85D and 1,6× that of the Taycan GTS J1.1. The gap narrows in winter but never reverses.
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.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the Taycan GTS J1.1 arrives in 7h31 with 4 charging 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.
Electric: 63,51 € (Model S P85D) and 70,99 € (Taycan GTS J1.1). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
