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 37 min for the Taycan J1.1 versus 4 stops totalling 49 min for the Megane E-Tech Electric 217.
The official WLTP figures (20,4 kWh/100km for Taycan J1.1 and 15,2 kWh/100km for Megane E-Tech Electric 217) 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 23,8 kWh/100km (Taycan J1.1) and 18,2 kWh/100km (Megane E-Tech Electric 217). Full methodology: see the dedicated button above the summary.
During the 37 minutes of charging for the Taycan J1.1, range recovers by 537 km. During the 49 cumulative minutes for the Megane E-Tech Electric 217, range recovers by 535 km. Per minute: the Taycan J1.1 recovers 1,3× faster. The gap is less pronounced but accumulates over long distances.
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 1,4× the electric cost of the Taycan J1.1 and 1,8× that of the Megane E-Tech Electric 217. 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 J1.1 arrives in 7h38 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: 85,12 € (Taycan J1.1) and 65,02 € (Megane E-Tech Electric 217). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
