Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: 2 stops totalling 42 min for the Seal U 160kW 2WD versus 3 stops totalling 76 min for the P7.
The official WLTP figures (16,8 kWh/100km for P7 and 17,0 kWh/100km for Seal U 160kW 2WD) 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 20,2 kWh/100km (P7) and 18,4 kWh/100km (Seal U 160kW 2WD). Full methodology: see the dedicated button above the summary.
During the 42 minutes of charging for the Seal U 160kW 2WD, range recovers by 414 km. During the 76 cumulative minutes for the P7, range recovers by 469 km. Per minute: the Seal U 160kW 2WD recovers 1,6× 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 Peugeot 508 1.6 PureTech 180 (equivalent segment) consumes about 7,2 L/100km on the motorway at 130 km/h. At 1,9 €/L, this Paris → Marseille trip would cost ~103 €. That is 1,5× the electric cost of the P7 and 1,8× that of the Seal U 160kW 2WD. The gap narrows in winter but never reverses.

The advantage comes from the combo real range + charging speed. On Paris → Marseille (775 km at 130 km/h), the Seal U 160kW 2WD arrives in 7h43 with 2 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: 66,75 € (P7) and 56,77 € (Seal U 160kW 2WD). An equivalent petrol SUV (~8 L/100 km) would cost about 115 € in motorway fuel. Electric costs less in energy but adds charging stops.
